Chapter One: How NOT to raise the Sun or Moon

Immediately after Discord left Twilight with two baby alicorns, Celestia looked down at the thick, pudgy diaper bulging out between her legs and gave it a curious poke. This made it crinkle quite loudly, accompanied by a cute poof of foal powder as she squeaked. "Oh wow, Wuna, we weawwy awe foaws. Tis is gweat!"

Luna was quite surprised and looked down at her own thick diaper, giving it a few curious pokes. "Yeah, wooks wike we wiwwy awe, Tia. And Twiwight’s gonna be ouw mommy."

Celestia waddled over to her sister and gave her tummy a poke. "Wook at aww tat foaw fat, bout time ya got some weight on ya!"

The alicorn filly blushed and pushed Celestia's hoof away. "Weww, ya fattew ten me! Ya need to stop eating aww tat cake."

Her sister snapped back. "Nuh-uh, I was onwy a wittwe fat, and cakes are yummy! Besides ,ya sneak into ta kitchen aww ta time steawin cookies! Ya a naughty fiwwy!"

Luna pouted and shouted. "It not steawin! My nighty night guawds make tem fow me! Besides tey dun make me fat wike ya cakes!"

Celestia snapped back. "Ya stop tat! Cake is bettew ten cookies!"

Luna stomped about and whined. "Cookies!"

"Cake!"

"Cookies!"

"Cake!"

Twilight was still trying to comprehend what was going on, so for a moment she just stood there and looked down at who used to be princesses of Equestria. Now they were two diaper dependant foals bickering over whether cake or cookies were better. She shook her head, stomped a hoof on the ground and shouted. "Hey, listen up you two!” The two foals looked up with surprise to see Twilight in a silly, pink apron with the words "Royal Nanny" printed on it in a frilly, cursive script.

The two foals couldn't help but snicker upon seeing Twilight in her embarrassing outfit as she tried to explain as calmly as possible. "Ok you two. I need you girls to calm down and do normal foal stuff. I don't want things to go crazy like they have with all the other regressed ponies."

Celestis started to bounce up and down on her thick diaper as she replied. "Wight, we wiww twy to be good foaws Twily. We pwomice we not gonna twy ta dwive ya cwazy."

Luna was blowing bubbles from her mouth as Celestia took a hoof, making the princess of the night squeak and babble. "Oh yeah! I too going to be good! I pwomice!"

Twilight giggled and dawwed seeing how cute the two foals were being as she knelt down and ruffled their manes. "Alright sweethearts. Come on, let's get you two some breakfast. I bet you're hungry." She hoisted the two foals up with her magic as they kicked about in their padding, making it crinkle with puffs of foal powder coming out from the leg holes.

Twilight dawwed once again as she nuzzled the two. "Oh, you two are so cute as foals! I bet this is going to be so easy ,and fun! I'm going to win Discord's bet no problem." She then brought the two baby princesses to the royal kitchen. There was a circular pink plastic table, with a tiled floor consisting of pink and white tiles. There was also a fridge with one side labeled "Sun Butt's food" while the other had "Moon Butts's food." labeled on it. Surrounding the table were two highchairs, one being white with Celestia's cutie mark printed on it while the other was dark blue and had Luna's cutie mark.

Twilight strapped the two in fastening the straps around their cute, pudgy padding. She then took out two jars of foal food from the fridge. One was cake flavored and the other was cookie flavored. Twilight shook her head. "This is clearly not healthy for two growing foals but whatever. If it keeps them from fighting, it's worth it. I can always make them go on a diet later if need be."

The mare turned her attention to the two princesses and began to spoon feed them with a small, pink rubber spoon. The princesses were munching on the foal food, some of it falling onto their bibs and all over their faces. Twilight just snickered as she continued to plop the foal food into their mouths.

When it was all done Twilight went about cleaning them both with a rag. However, the two princesses started to get antsy as Celestia was sticking a hoof up her nose as she asked. "Hey, Woona, what ya wanna do as a baby?"

Luna shoved a hoof into her mouth with drool pouring down her chin as she mumbled. "Hmm, what if we twy waising ta sun and moon? Ya tink we can stiww do it as babies?"

Celestia squealed and started to bounce up and down in excitement, making giant clouds of foal powder puff around her as she shouted. "Yeah! Wets do it!"

Twilight (having overheard) got quite concerned and responded. "Ih...I don't think that's a good idea. We should try some simple spells first to see if you're re-" But before she could stop them, the two baby alicorns lit their horns and the princesses teleported away in a big puff of smoke. Twilight squeaked and ran around the castle, shouting, "Celestia! Luna! Get your flanks back here, now!"

The princesses both appeared on top of the castle overlooking Canterlot. Luna looked up into the sky and eyed the sun. She squinted her eyes and groaned as her horn lit up with a purple aura. The sun slowly disappeared, and the moon rose up in the sky. Upon opening her eyes, she smirked, looking up at the moon and responded. "There! Ya see, Tia?! I can raise ta moon!"

Celestia laughed as she waddled over and poked her sister's padding making it squishaudibly as it was now soggy and stained yellow. The princess of the sun jeered. "Ha ha, ya pee-pee in ya diapee!"

Luna brushed her sister's hoof away and whined. "Stop it, Tia! I a baby now! Besides, ya sometimes wet ta bed when ya was a big pony! Ya did it even aftew I came back fwom ta moon!"

Celestia's face flushed red as she cried. "Hey! Stop tat, Wuna! Ya pwomiced nevew to say tat!"

The princess of the night crossed her hooves and babbled. "I sowie, but ya was being a big meanie!"

The princess of the sun whined. "Weww ya pee-pee ta bed too sometimes aftew ya came back fwom ta moon. I even hewped ya weawn how ta use ta new potties! So we even!"

Luna blushed, remembering how Celestia had to potty train her a little after coming back from the moon (not only did the moon not have potties, but plumbing fixtures in Equestria had changed drastically in a thousand years) and sighed. "Awight, fine. Now can ya waise ta sun, wets see if ya can do tis!"

Celestia squinted her eyes like her sister did and grunted, lighting her horn as the moon started to lower and the sun rose up again. But she also let out a loud hiss and squealed upon seeing her diaper was now soaked in urine.

Luna burst into laughter, rolling on the ground and kicking about in her soggy padding as she babbled. "See ya pee-pee in ya diapee too, Tia!"

Celestia cried, crossing her hooves over her yellow-stained padded front and whined. "Fine, ya win, Wuna! I guess we pee-pee when we use too much magic."

Luna nodded as she sat up and poked her padding, making it squish under her hoof as she babbled. "Wight. Now Twily gots to change owa diapees, tey soggy and gwoss."

Celestia looked up at the sun and gave a long sigh as she whispered. "Isn't ta sun so cool tough? It feels so wawm and good!"

Luna looked up and shrugged her tiny hooves as she replied. "I tink ta moon is bettew. It big, it gwows and feews good on ya."

Princess Celestia snapped. "Nah uh! Ta moon stinks! Tat means we gots to go sweepie times! Now we foaws, so we gots to go to sweep eawy!"

Luna pouted and shook her head. "Nah uh! Ya dun need to go sweepies! We foaws so we gonna cwy and pee owa diapees duwing ta night awot anyways! Besides when ya sweep ya get coow dreams too!"

Celestia shook her head and babbled. "I tink ta moon wooks wike a big diapee! Wike ya padded butt!"

Luna got flustered and shouted back. "Tia, sun wooks wike a big, stupid diapee design! And ya a poopy head!" She lit her horn, and the moon rose up again despite Luna soaking her diaper even more.

Celestia had a look of anger on her face as she roared, "Nah uh, ya a soggy butt! Ta sun is bettew!" The princess closed her eyes and grunted, raising the sun once again despite peeing her diaper again as well.

"Sun!"

"Moon!"

"Sun!"

"Moon!"

This fight went on for some time with the two princesses having soaked their diapers so much that they were drooping between their legs. Meanwhile, the sun and moon flickered back and forth across the sky.

Twilight just gulped as she looked out a window and up at the sky, seeing the sun and moon rising and falling rapidly and squeaked out. "What's going on?!" She then tapped a hoof to her chin and gasped. "The princesses! They have to be on the roof! Oh, I should’ve known they’d still have their magic!" The unicorn squinted and teleported instantly onto the roof of the palace to see the alicorn babies shouting and grunting while raising their respective celestial bodies.

Twilight's face turned bright red and steam billow out of her nostrils as she ran up to the two fillies while shouting. "Hey, you two! Stop that right now! You’re going to make everypony confused!"

The baby princesses both turned to the angry mare as Celestia asked. "Hey, Twily, what do you tink is better? Ta sun or ta moon?"

Luna turned around and asked. "Yeah, which one, Twily? Ta Moon is so much bettew, wight?"

Twilight roared, taking the two into her magic and replied. "Neither, they are both good. Now stop doing that, you're probably freaking everypony out in Equestria right now!"

Celestia shook her head and whined. "Nuh-uh, tey love ta sun! Watch, I’ll give it a smiley face!" She then zapped the sun with a burst of magic. It now had a big, goofy smile printed on it. The baby alicorn clapped her hooves and squealed. "See?! Now ponies will wuv ta sun more!"

Twilight was only horrified upon seeing the sun with its goofy smile. She turned and shouted, "Celestia, you return the sun to normal this instant, missy!"

Luna snapped back. "Yeah! Ya can't do tat! I wana make ta moon better!" She zapped the moon with her horn. The moon was now a ball of cheddar cheese with holes all over it. The baby alicorn rose up with a big smile on her face as she chirped. "Tere, now ta moon is made of cheddar cheese! Everypony wuvs cheese! Maybe I’ww tuwn it gween!"

Twilight squeaked at what she saw and snapped. "Hey, I said to stop that!"

But before Twilight could do anything, Celestia and Luna both disappeared in a puff of smoke, and they suddenly appeared on top of a tower.

The baby princess of the sun exclaimed, "I gonna make my sun be made of someting coower!" She shot her magic at the sun as it turned into a giant sun-shaped cake. "See It now ta sun is made of cake! Cake is better ten cheese!"

Luna whined and stomped about as she shot her magic, turning the sun into a giant, folded up diaper with Celestia's cutie mark on it. Celestia cried out as Luna clapped her hooves and squealed. "Tere! Now ta sun is a diapee!"

Celestia, with an angry pout on her face shot a beam of magic and turned the moon into a giant, folded diaper with Luna's cutie mark printed on it. “And ta moon is a diapee too! We even!”

Twilight was beyond angry at this point! She teleported over near the princesses and stomped a hoof while shouting. "You two get down here this instant! I mean it! You shouldn’t be up that high!"

Celestia looked down at Twilight and shouted. "Dun wana come down! Not until Wuna changes ta sun back to nowmaw!"

Luna snapped back. "Ya change ta moon back to nowmaw fiwst, Tia!"

Celestia snapped back. "Nuh-uh, ya fiwst!"

Luna kicked about and whined. "Nuh-uh, ya fiwst!"

Twilight stomped her hoof down quite angrily and snapped. "That’s enough! You're both going to be in big trouble if you don't change the sun and moon back to normal right now! Do you understand?!"

The baby alicorns both grumbled, but their horns lit up and shot their magic at the celestial bodies, reverting to their normal forms. Twilight turned her attention to Luna. "Now Luna, please lower the moon. You can raise it later tonight, ok?"

Luna gave a nod and grunted as she lowered the moon. She started to pee in her diaper again and squeaked as the sodden padding plopped onto the ground. Celestia burst into a fit of laughter, making Luna roar as she tackled her sister. However, they both rolled off the tower and began falling fast!

Twilight squealed in horror as she positioned herself under the falling alicorn babies and caught the two foals in a beam of magic. She slowly placed the foals, gently on the ground. She was still glaring at them, but tears started to well up in the foals’ eyes, and soon the alicorns began bawling.

Twilight had to hold her hooves to her ears and lay on her belly and braced herself. She tried to hold on, but she almost got thrown off the castle with the wails of the baby alicorns creating waves. She then had to crawl her way through the waves of screams slowly.

At last Twilight made it to the two baby alicorns, who were bawling their eyes out. The mare took them into her magic, pulled them into a hug and plopped two pacifiers into their mouths. The wailing suddenly stopped as the babies suckled on them and calmed down as Twilight hushed and sang gently to them. It took some time, but they eventually fell asleep in her hooves, and Twilight gave a sigh of relief. "Hopefully that's the end of that. Can’t believe I forgot about the Royal Canterlot Voice, or in this case the Royal Canterlot Temper Tantrum."

She then plopped the sleeping foals onto her back, and she climbed into a nearby castle window. Then the mare plopped down and waddled across the seemingly empty castle.

Eventually though, she entered a room that was labeled "Sun Butt and Moon Butt's Nursery." At least someone had been considerate enough to leave that for her. She slowly opened the door to see a giant nursery. The left side of the room had a pink colored wall with smiling suns and cakes painted over it; the carpet had little cakes and suns printed on it. The crib was big with pink bars and baby blankets with Celestia's cutie mark printed on them. The right side of the wall had a purple colored wall, with sleeping moons and cookies painted over it: and there was a purple carpet with little cookies and moons, along with a big crib with purple bars and baby blankets with Luna’s cutie mark printed on them.

In the middle of the room was a big pink and purple padded changing table with Twilight’s emblem printed on the front. Twilight gave a deep sigh and shook her head. “Only Discord could’ve conjured this up. What did I ever expect?” She thought aloud.

Twilight proceeded to hover the foals over to the table, placed them upon it and after untapping Celestia’s diaper started to clean both foals’ rumps and crotch areas. They both were still tearing up, and Twilight tried to hush them. "Hey, it's ok. I know you’re babies now, and your minds have probably been altered a little due to the regression. Just listen to me, and everything will be okay. Now come on, let's get you two changed and settle you in for a nap."

Twilight tried to be gentle with the two fillies kicking and cooing. Twilight then gave each of their rumps a thorough powdering and made sure their rumps were as white as could be. The mare then began to strap them in new poofy (and crinkly) diapers. The mare stood up to admire her work but squealed with a blush growing on her face upon seeing she taped the wrong diapers on the wrong babies. Celestia had Luna's cutie mark on her diaper while Luna had Celestia's cutie mark on her diaper.

The unicorn rubbed a hoof across her face and sighed. "Whatever, they’re just diapers so it’s no big deal. Maybe it’ll help them appreciate each other more."

Twilight then plopped Luna in her crib and slowly tucked her under the sheets. "Ok sweetheart you behave, alright? And don't do any dream walking as a foal."

Luna yawned and babbled. "Otay Twily, I pwomice."

The mare then went to Celestia's crib, tucked the princess in and kissed her on the cheek. "You behave as well and don't try doing anything silly with the sun."

The princess nodded as she babbled. "Otay Twily, I pwomice. But ya gots to give me a wettew bout fwiendship stiww! I haven’t had one in a wong time."

Twilight snickered. “Sure, I'll think of something,” She then walked towards the door and cooed. "Please behave and take a nap, alright?" The two foals nodded as the mare closed the door and sighed. "Please take a nap, I need to go tell the citizens of Equestria that they have nothing to worry about. Hopefully I can somehow explain that the regression situation is under control." She thought to herself.

Chapter Two: How NOT to Potty train Alicorn Foals

Cannon Feather and Bucket Bridle were in the castle's playroom when Discord turned it into a giant nursery for Luna and Celestia. The two foal guards were busy with their "homework" trying to learn their shapes and colors. Cannon Feather was busy trying to draw circles with crayons while Bucket Bridle was using crayons to color by the numbers. Since their room was already quite, foalish nothing changed, and as a result, they didn't notice anything until they heard the baby alicorns wailing from above the castle.

Cannon Feather rubbed his head with a hoof and grumbled. "Wha's going on, is Mommy ok?"

Bucket Bridle stood up and shouted. "We gots to find tem and make suwe tey otay! We still woyal guawds, we gotta pwotect the pwincesses!"

The two waddled off together outside and gasped upon seeing the palace was quite different from what they remembered. It now had pink plush floors, and plushies and teddies were walking around the place. The two both were looking around the palace completely confused and amazed at what they saw.

They hurried along until they found a door labeled "Sun Butt and Moon Butt's Nursery." The two toddlers blinked in surprise and opened the door to find Celestia and Luna both sleeping soundly. Cannon Feather gulped as he whispered. "Hey, Bucket Bwidwe is tat ya mama?"

Cannon's adopted cousin gasped upon seeing Celestia sleeping soundly and slowly nodded as he babbled. "Yeah, it is. Wooks tey gots tuwned into babies too somehow. So what ya tink we can do to hewp tem?"

Bucket Bridle shrugged and babbled. "Not suwe but wets get going! We gots to hewp tem get back to being big ponies! Equewstia needs them!"

This caused the two alicorn foals to wake up while rubbing their eyes, and Luna cried in surprise. "Who woke us up?!"

The two regressed princesses turned their attention to the two toddlers. Celestia got up first, holding the bars of her crib while showing off the diaper between her legs. She shouted in surprise. "Hey Cannon Feathew, Bucket Bwdiwe! Ya two awe stiww hewe?!"

They both nodded as Cannon Feather babbled. "Yeah, we came to hewp when we heard ya cwies! Why ya babies?"

Luna blushed as she tried to cover her padded front with her hooves (to no avail) and explained. "Is a wong stowie, Cannon Feathew. Can ya hewp us? Twily changed owa diapees, and she messed up by putting us in ta wong diapees!"

The two colts nodded as they went about taking the two fillies out of the crib and laid them down on the nearby changing table. They then began to change their diapers and stumbled about, pouring an entire container of foal powder over the two. The regressed princess coughed and whined, kicking about as the colt littles strapped them in diapers with Celestia in a thick diaper with a sun printed on it, and Luna in a thick diaper with a moon printed on it. Afterward, they were raised back up, and Cannon Feather rubbed his head and asked. "So, what we gonna do, Mommy, and Auntie Cewwy?"

Celestia, happy to be back with a diaper with her cutie mark on it, was busily bouncing up and down. "Dun know." She admitted.

Luna babbled. "Ya know, why dun we try potty twaining? Kind of wike I potty trained ya, Cannon Feathew?"

Cannon Feather nodded. "Sure, wets twy it! Just gotta be carefuw, so ya dun get fwushed!"

"Bwight Wing's never gonna bewieve tat when he heaws!" Bucket Bridle laughed. "Gotta wespect the big potty."

"It not scawy!" Celestia huffed. "Ya dun have to wowship it!"

Luna just commented. "Tat why you caww them ouw othew thwones?"

Celestia just groaned, then they waddled out to the throne room where Celestia and Luna's thrones used to be. But now there were two training potties with their respective cutie marks on them. Bucket Bridle scratched his head and asked. "So wha happened to ya thwones? Tey twaining potties now?"

Celestia sighed. "It's a wong stowie, I'ww teaw ya watew, wight now wets twy going potty wike big ponies! Good ting I wemembew how to do it!" She waddled over to her training potty and blushed upon seeing her diaper was still on. "Uh, oh! Bucket Bwidwe, can ya hewp me with my diapee?" She asked her son, embarrassed at needing to have him help her instead of the other way around.

The little colt gave a nod, waddled over and helped Celestia remove the diaper before she plopped down onto the training potty.

Luna turned to Cannon Feather and asked him. "Can ya hewp me too?" The little colt squealed with delight as he waddled over and helped take off her diaper.

Soon the two little fillies plopped down onto the training blushing as they waited to tinkle, which they did. The two colts both cheered making the princesses happy and giddy kicking about in glee while shouting. "We went, potty!"

Cannon Feather then asked. "Gweat! Why don't we twy the big potties in the bathwoom? Maybe if ya gets potty twained on tem, ta speww wiww be gone wike in a faiwy tawe!"

They nodded in agreement, the princesses wanting to prove they were still big ponies and capable of big pony responsibilities. But suddenly, the training toilets turned into a giant, real toilets with Celestia's being pink and Luna's being purple! The two squeaked as they kicked about on the edges of the seats, crying out! "Eep, is so big! Hewp!"

Cannon Feather gasped as he tried to fly up to them. "I'ww save ya two, dun wowwie!" But it was too late; the two fell into their toilets with a big splash!Cannon Feather shouted! "Bucket Bwdiwe, thwo something ovew hewe so tey can swim! Quickwy!"

Bucket Bridle took the two diapers the princesses left behind and shouted. "Use tese!" He threw them at Cannon Feather, who snatched them up and threw one in each toilet. The foals grabbed onto the thick diapers that expanded in the water as they began to float above the water, gasping for breath and kicking about.

Luna was quite scared as she shouted. "How do we get out of here without getting fwushed?!"

Celestia cried. "Not suwe! We dun know how to fwy yet and we soaking wet! But I dun wanna go down ta howe!"

Cannon Feather turned to the diapers as he noticed they were expanding, sucking up the water. He shouted at the princesses. "Use ta diapees! Cwog up ta toiwets! It wowked fow me once!"

Luna and Celestia shrugged as they took their diapers and immediately plugged them into the holes.

Bucket Bridle then flew up and shouted at Cannon Feather! "Wha ya doing?! Tey need tose diapees!"

Cannon Feather just went to the lever of the purple toilet and shouted. "Ta diapees awe gonna cwog up the howe! When we fwush ta water wiww come down and tey wiww wise up!"

Bucket Bridle gasped and squealed! "Ya tink that wiww wowk?"

Cannon Feather nodded. "Wemembew ta time Bwight Wing fwushed his diwty diapee down the toiwet and it fwooded the bathwoom? Diapees dun fwush. And tese diapees wiww wowk ta same way."

Bucket Bridle nodded in agreement, that made sense. He could even remember how furious Celestia had been to discover the flooded toilet when Bright Wing had done that during their last sleepover at the castle. "Otay, wets do it!" He turned to the lever on the pink potty as he flew over to it. Looking across to Cannon Feather, they both pressed down at the same time, making the water rise. The two colts grabbed their scared moms but squeaked as the water started to pour out onto the floor, making a small pool. Cannon Feather and Bucket Bridle waddled across the floor and got onto a giant toy boat that was seemingly coming out of nowhere, watching as the toilet water steadily rose.

Cannon Feather and Bucket Bridle began fighting and shouting about who should be captain of their ship, while Celestia and Luna gulped knowing they were going to be in big trouble with Twilight for this!

Twilight (unaware of what was happening miles away) was quite nervous while standing in front of a podium, looking over the ponies of Canterlot. She was quivering as they looked up with confused looks, all waiting for her to explain what was going on. "All you need to know is that Celestia and Luna have regrettably been turned into foals. They will be like this for a month, and until then I will run things. Any questions?"

The ponies all started and demanded more answers. One shouted! "Why did the sun and moon turn into diapers and go all crazy?!"

Twilight squeaked and stammered. "Uh...well...I don't have a lot of answers for that right now. But I promise that I will do better in keeping Luna and Celestia under control."

But suddenly, Moonlight Glimmer appeared and declared. "Everything has gone according to my plans! Don't worry, ponies of Equestria, I will now control things and turn all of you into foals. Nopony can stop me now! All your heroes have been reduced to helpless babies! I will be your mommy, and you'll hang on every word I say!"

The crowd screamed, and everyone gathered ran for their lives before the alicorn could use any of her magic. However, the magic exploded, and she squeaked as her body began to shrink, and her wings grew larger! She slowly regressed into an alicorn foal, looking at the thick diaper between her legs. She whimpered. "H...h...how did tis happen? Tis wasn't pawt of my pwans!"

Discord suddenly appeared behind the foal. He picked her up by the seam of her diaper and cooed. "Now now, Midnight. As much as I would love to see everypony in Equestria turning into foals, I think it might not work out as well as you think. I certainly don't need a kingdom of foals and only one mommy."

Twilight blinked in surprise and asked. "Discord, why would you do that? Midnight was responsible for the original foal pandemic!"

The lord of chaos shrugged his paws as he responded. "Well, I didn't do it for you if that's what you're thinking. I feel that there can only be one Lord of Chaos. And on top of that I want to regress ponies, but in fun and different ways, and not for malicious purposes like she did!" He held Midnight up further as he declared. "Now, I'm going to drop this little one off with a 'special princess' who wants to see her, then I'll continue to watch you try to care for Celestia and Luna. By the way, you might like to know that they're awake and are flooding the castle."

With a flick of a claw, he disappeared while Twilight roared, hearing what the foals were doing and ran back to the castle as fast as she could! "Oh, they are gonna be in so much trouble for this! They better not have done what I think they did!"

Twilight entered the palace and squeaked as she immediately fell into a giant pool of water with a big splash!The mare gasped, paddling about with her hooves as saw she saw that the entire ground floor of the castle was flooded entirely in water with two toilets in the back of the room! Said toilets continuing to pour water out, and strangely they seemed to be the same colors as the training potties for the regressed royal sisters.

"Celestia! Luna! Where are you?!" Twilight called and continued to swim through the water, until she came upon a plastic toy boat, with all four foals giggling as they were pretending to be pirates (Cannon Feather and Bucket Bridle even had eye patches and cardboard swords)

Dodging a blast of confetti from one of the cannons, Twilight's was able to get onboard the plastic toy boat. She eyed the foals and asked. "Alright, what happened? How did the entire castle gets covered in water like this?!"

Luna whimpered and began to whine. "We sowie, Twiwy! We just wanted to use our potties, and tey tuwned into big potties!!"

Celestia nodded and babbled. "Yeah, is twue. We wanna use ta potty wike big ponies, but ten everything gots messed up! We sowie!"

Twilight sighed as she looked around "At least this time nopony got flushed. Rarity mentioned how that happened with both of her foals, as well as Cannon Feather." She thought to herself. Then she saw a giant plug in the middle of the room. Her horn lit up and took it out! She squeaked as the water started to circle the drain, with the foals squealing as Twilight shouted, "Make it stop!" She closed her eyes as the water eventually was all drained away, and they plopped onto the ground, the foals bursting into laughter.

Twilight groaned as she took out some diapers and foal powder and began putting Celestia and Luna back into said diapers as she grumbled. "Look, I know this is tough for you two, being foals and all. But you can't go around flooding the castle with toilet water. Especially not to the extent you just did, turning the whole castle into a river!"

Cannon Feather waddled over and explained. "We sowie is not their fault. We put tem on the twaining potties; ten tey turn into big potties. We just wanted to hewp them potty twain."

"And Cannon Feathew made them fwood so we cowud save ouw mommies." Bucket Bridle explained.

Twilight gave a deep sigh, seeing that the training potties were now two big regular toilets. "Discord!" She realized. "He's going to mess with me now and make this ten times harder. I should've known."

Bucket Bridle blushed and asked. "Twiwy, what happened? Why is my mama a baby now?"

Twilight sighed, taking the foals over her shoulder. "Let's get you all something to eat, and I'll explain everything," And she turned to Celestia and Luna. "And I think we need to talk about you trying to do things without me around. I can't risk more accidents like this."

Celestia and Luna were now in their highchairs suckling on foal bottles filled with formula, while Cannon Feather and Bucket Bridle ate peanut butter and zapped apple jam sandwiches and drinking down sippy cups filled with milk. While they ate, Twilight explained everything that happened to Celestia and Luna and explained the situation with Midnight Glow as well.

Princess Celestia popped the bottle from her mouth as she rolled her eyes and babbled. "I dun know if I shouwd either tank Dissy fow stopping Midnight or spank him fow pwanking us wike tis!"

Luna nodded and replied. "Yeah, he nice and mean? What is tat wike? He just doing tis to watch us be foals?"

Twilight shrugged and sighed." I'm not sure what his intentions are, but I do know one thing. I can't handle four foals. After you're all done eating, I'm going to take Bucket Bridle and Cannon Feather to Cadence and Shining. I've sent them a letter explaining things."

The two toddlers cheered as Cannon Feather shouted. "Yeah! Can't wait to see Bright Wing!"

Bucket Bridle cheered. "I hear his daddy's marrying Caddy. He's gonna have a pwincess mommy wike us!"

Twilight nodded. "They're due to begin rehearsing for the wedding at the end of this month, so you two better be on your best behavior for them. Especially for Shining Armor, he's my B.B.B.F.F. So if you give him a hard time I'll know," She then took out a two-seated stroller and snapped Celestia and Luna inside making sure the straps were snug. Then she turned to the colts and cooed. "Now come on, you two can walk. So let's set off." She then strapped a giant diaper bag around her shoulder, straightened her apron, and started to lead the four foals out of the castle and into the streets.

Once out and about, Twilight blushed and kept her head down as she pushed the stroller through the streets of Canterlot. Many ponies gave her odd looks, but she did her best to try not to give out any impressions other than the fact that she was caring for the foals.

After a while they eventually came upon the house Shining Armor lived in when not overseeing the royal guard (usually whenever he couldn't bring Bright Wing to the barracks with him). And after Twilight knocked Cadence opened the door with a bright smile. "Hello Twilight, it's so good to see you!" The princess hugged Twilight in a huge hug and they emberced each other for a few moments. Then Cadence turned her attention to her foalified aunts who were blushing and scrunching their diapers with their forehooves as she cooed. "So these two are Aunt Celestia and Aunt Luna? My, they're just so cute!" Cadence nuzzled the two and blew raspberries in their tummies, making them giggle and squirm.

Luna cried out. "Hey, stop tat! Ya gonna make us pee!" It was too late, a pair of loud hisses emanated from the diapers.

Cadence dawwed. "Oh, that was adorable. It looks like my aunts are going to need lots of diapers," She then turned her attention to Bucket Bridle and Cannon Feather. "Alright you two, come on in! I haven't told Bright Wing that you were coming, so go surprise him!"

The toddlers both squealed as they ran into the house while shouting. "Tanks, Auntie Cady!"

Twilight chuckled, watching the toddlers run off before she sighed. "Thanks, Cadence, I wouldn't mind caring for all three of the foal guards, but these two are a hooful as it is!" She gestured to the alicorns.

Cadence waved a hoof. "That's alright; you're going to do fine, Twilight. Just try to remain calm and enjoy this. I know Shining and I will, as will Bright Wing. I can't wait to become his mommy officially," She then lit her horn and started to lift dozens of packages of diapers, drifting them underneath the stroller as she cooed. "I have so many extra diapers from all my years as a foal sitter. I think you can use a few."

Twilight blushed as she squeaked upon seeing how many diapers under her stroller. "I don't think I'll need that many diapers! Discord stocked the nursery quite well."

Cadence scoffed, as though offended at the very notion. "How could the Lord of Chaos know how to care for foals? Now, I'm not done," She cleared her throat, then lifted many jars of foal food, including Mashed Peas as both foals made gag sounds at that. She then lifted something very embarrassing; a milk pumping machine and cooed. "This is something I kept just in case if I ever had a foal of my own. I think you can use it for now if the need arises. It might not be a bad idea to talk to your mom about it; she did it for you and Shining a couple of times."

Twilight's face was a deep red as both baby alicorns burst into laughter. All the unicorn could do was stammer. "Th..thanks, I guess? I don't think I'll use it though. It looks uncomfortable."

Cadence patted Twilight on the back and reassured her. "Hey, I said you're going to do fine, and I mean it. Now, I have one more thing to give you before you leave. This is something Shining says has helped him a lot with raising Bright Wing," She then took out a giant book that read: How to Care for Foals: The Ultimate Guidebook on Child Raising. The mare then continued, "This has everything you need to know, and knowing you, I bet you'll read it all in a few days." She stuffed it under the stroller.

Twilight looked up at Cadence. "Thanks, I appreciate this. And tell Shining I said hello."

Cadence gave a nod. "Will do. Now do me a favor and please take pictures! I wanna see some super cute photos of those two in diapers! It's not like they had cameras a thousand years ago!"

Twilight smirked, looking down at Celestia and Luna who were both squeaking at what Cadence said. The unicorn snickered. "Oh yes, I'll be sure to get some very adorable pictures and make an entire photo album." She then took the stroller and began strolling back to the castle with a bit more confidence. She could handle this.

Chapter three: How NOT to Crash a Wedding

It was now late into the night as both Celestia and Luna were in their nursery, flying around and throwing plushies at each other in a playful fight. Twilight, for her part, was chasing the two rambunctious foals around with steam coming out of her nose while shouting. “Stop this at once! You two need to get your sleep! All foals go to bed when they’re told or they get cranky, so please go to sleep!”

Luna plopped onto the ground with her diaper crinkling quite loudly as she cried. “Dun wanna! I gonna stay up aww night wong. I ta Pwincess of ta night!”

Celestia flew next to her sister, landing with a loud, crinkly plop from her diaper as she babbled. “Yeah! If Wuwu stays up I wanna do it too! Not faiw tat I gots to go to sweep eawiew."

Twilight wasn’t in a mood to argue, it had been less than a day and already she was growing frustrated. So she stomped a hoof down and ordered. “That's enough! Until you’re adults again you will listen to me and go to sleep right now! Stop making this difficult for all of us!”

The princesses looked into Twilight’s eyes, seeing how annoyed and angry she appeared to be. Any desire they might have had to keep misbehaving faded away right then and there. They both fluttered down and into their respective cribs.

Twilight then went to each foal and started to tuck them under the blankets as she cooed. “Now, I’m putting a baby monitor on, so you better not do anything naughty or stay up late, because I’ll hear it. And I’ll punish you both very harshly!”

Celestia sighed as she scrunched the padding between her legs, making it crinkle as she babbled. “Otay, Twily, we be good.”

Luna kicked in her padding, making it crinkle as well. “Yeah, we be good foaws, we pwomise!”

Twilight eyed the princesses and growled under her breath. “You’d better, I don’t know how much more of this I can take,” Then she sighed, taking a deep breath. “Now before I go, do you two need anything?” The two princesses their heads and Twilight went about giving them a kiss on their foreheads. “Okay then, goodnight you two. And remember, Luna, no dream walking. I read that foals your age might mess up other ponies dreams if you do that.”

Luna pouted wanting to dream walk, but at the same time she didn't want to make Twilight more angry so she mumbled. "Otay I wun dweam wawk. I pwomise."

“Good. See you both in the morning.” Twilight declared. She then slowly closed the door and left.

But the two baby alicorns waited to hear Twilight leave, before Celestia got up, using the bars on her crib and showing off her cute, thick dark blue nighttime diaper with her sister's cutie mark printed on it to her sister as she whispered. “Hey, Wuwu, I need to ask you someting.”

Luna chuckled and also stood up, using the bars of her crib while also showing off her cute dark blue diaper to her sister as she asked. “Suwe, wha is it? Awso, tat diapee with my cutie mawk wooks good on ya.”

The sun princess got a little flustered and scrunched her padding between her legs as she whined. “Not my fauwt! Discowd didn’t suppwy us with nightime diapees with my cutie mawk!”

Luna bounced up and down in excitement. “Yeah, tat too bad! So, wha ya wanna ask me about?”

The princess of the sun whispered under her breath. “Wook, I gots to do something impowtant tomowwow. I gots to go to a wedding.”

The night princess gasped and exclaimed! “Oh yeah! Ya suppose to be one that says ‘Ya may now kiss ta bride’ and stuff! I wanna do tat too!”

Celestia, getting excited like her sister, started bouncing up and down thus making foal powder poof out from her padding. “Weww of couse, ya a pwincess! Is one ting we do fow famous ponies and stuff!”

Luna eyed her sister and whispered back. “But, how we gonna do tat? I mean we foaws and aww. Ya evew heawd of foaws hosting a wedding?”

The princess of the sun plopped onto her diaper in a cloud of foal powder and started to suckle on her hoof. “I dun know, but I pwomised ta do it, and I tink it would be supew cute if I did tat as a foaw. But I need ya help to covew fow me.”

Luna gave a disappointed sigh as she babbled. “Fine, I’ww twy. But if Twiwy finds out we did tis she gonna be supew mad at us.”

Celestia rolled her eyes and responded. “Weww, aww we have to do is make suwe tat she nevew does.” Her sister crossed her hooves and scrunched her diaper between her legs as she declared. “Ya gonna owe me big time for hewpin ya.”

Celestia blushed as she babbled to her sister. “I’ww be sure to think of something, I pwomise.”

Luna snickered, seeing her sister being so happy. Then whispered. “Uh...I...I...” The princess of the sun eyed her sister as Luna suddenly lit up her horn and teleported from her crib into Celestia’s. The princess of the night snuggled herself into her sister as she babbled. “I wanna sweep with you. Is been too wong since we wast swept together.”

The princess of the sun snuggled her sister with their diapers crinkling, and as they scrunched together she cooed. “Yeah, I so happy we together. We need to do tis more often.” They nuzzled each other as the two sisters hugged each other and drifted off to sleep.

Meanwhile in another part of the castle, Twilight was quite exhausted from the day’s events. She slowly walked down the hallway of the castle and headed to her room to rest. As she approached she looked up with wide eyes and saw that above her door read “Room of the Royal Nanny.” Twilight rolled her eyes seeing Discord at work, and slowly opened the door to reveal quite a large bedroom with a huge canopy bed. There was a purple carpet stretching out beneath her hooves, a spa in the corner of the room, and a bookshelf filled with all kinds of books on raising foals.

She then turned to see that across from her bed was a closet and inside were dozens of aprons. She even noticed a few maternity dresses, which made her blush and whisper under her breath. “Oh my...Discord really went all out here. I guess I should’ve expected that,” The mare slowly took off her apron. After hanging it up she took out the books Cadence had given her and started to read through them. She then placed all the other foal stuff that Cadence gave her aside and snickered. “I have so much foal stuff, I can probably run an entire day care here. If only Celestia and Luna weren’t so hard to keep out of trouble. If today is any indication, I’m gonna have to foalproof the entire castle from top to bottom.”

Twilight then decided to walk over to the spa to unwind, slowly she dipped her body into the large, soapy waters, letting the pink suds soak around her body. The mare sighed quite loudly as she relaxed. “Oh my gosh, this feels so good! I haven’t had a bath like this in ages!”

Twilight must have been in the spa for quite some time, but the mare eventually got out. When she looked into the mirror and saw that her body had grown a little, she shrugged and went to bed. “I’m probably just going to be taller so I can look more like a princess. I’ll go back to normal when this is over.” She thought, then she snuggled underneath her sheets and sunk into the comfortable mattress, reading that big book on raising foals. However the relaxing bath she took had made her feel very comfortable as she began to feel sleepy. Soon after her eyes began to droop and she slowly fell into a deep sleep.

Celestia and Luna both were quite surprised when they woke up the next morning, looking up at Twilight. Before their eyes the mare from the night before was now taller and had purple feathered wings sprouting from her back. The baby alicorns babbled excitedly, trying to tell Twilight about her new body. However, the mare was quite tired and didn't seem to notice as she went about changing the princesses soggy diapers.

After their diapers were changed Celestia raised the sun (then her diaper was changed a second time as the strain from raising the sun had caused her to suffer a humiliating accident). Then the two baby alicorns were taken to the kitchen for breakfast by a tired Twilight, who still didn't seem to notice what had happened to her body just yet.

The two princesses snickered and giggled as they ate a breakfast consisting solely of oatmeal, and Celestia upon seeing Twilight wake up. The sun princess eventually had to point out. “Hey Twiwy! Ya noticed something stwange about ya?"

Luna, munching on her oatmeal, chimed in. "Yeah, ya notice tat ya gots wings and wook a wot tawwew?"

Twilight shrugged as she yawned and stretched as she replied. “I’m not sure what you two are talking about, I feel fine…” But then she gasped upon seeing the massive wings sprouting from her back! “What?! Where did these come from?!” The mare circled around herself and shouted, “Discord! This must be his chaos magic! Ugh! What else is he going to do to me?!” She then placed the foals down in a giant, pink playpen in the throne room as she grumbled. “Alright you two, just stay here for right now. I’m going to find Discord and give him a piece of my mind.”

After Twilight stormed away, Luna turned to her sister and exclaimed. "Hey sissy! If ya wanna go to tat wedding, you shouwd go wight now!”

The baby alicorn nodded and exclaimed. "Wight, I better get going! Wish me wuck!" She slowly closed her eyes and squinted until she teleported away in a puff of smoke.

The wedding itself was in the heart of Canterlot, with the sun shining down at a makeshift altar under an arch made of flowers.

Battleheart, a chestnut coated stallion with blonde locks and red eyes was dressed in a snazzy tuxedo, standing at the altar. He was blushing as he turned to look down the aisle where there were dozens of ponies in the crowd, along with five foals he and his special somepony had adopted. Said foals currently being held by a portly unicorn nanny.

Battleheart waved a hoof as they babbled and raised their hooves at him. Then he blushed as he fixed his bowtie, as he saw a mare named Morning Dew come down the aisle in a lovely white, flowing wedding dress. She was a young, white coated unicorn mare with a lovely gold mane and blue eyes. The mare flashed her cute eyelashes at him and slowly walked over to her soon to be husband.

They stood there for a moment, looking deep into their eyes. The mare blushed as she asked Battleheart. “So...are you ready for this? I know that things between us have been... you know... hard when we suddenly adopted five kids.”

Battleheart rolled his eyes and grumbled. “Yeah, it's definitely been hard. Those five foals have literally been driving me crazy. So many diapers and bottles!” The mare was quite surprised to hear this, but the stallion nuzzled her face and whispered. “But...I wouldn’t ask to do it with anypony else. With you by my side I know we’ll raise those foals right.”

They then turned to see the altar, where Celestia was supposed to be nopony stood. Braveheart sighed, “I guess we couldn’t find a pony to replace Celestia.”

Morning Dew chuckled. “Well nopony would have expected Celestia and Luna turned into foals. I guess we could just skip the whole speech part and just say our ‘I do’s’?”

Braveheart nodded and exclaimed. “Sure, why not?! That way we can get to the fun part faster! But who should say it first?”

“Stop!” The two ponies squeaked as they looked around in time see Celestia appearing on the podium, bouncing up and down on her padded rump! “Ya two not gonna say anything untiw I say someting,” Many of the ponies in the crowd laughed and dawwed at Celestia being quite cute. Undeterred, the princess continued. “Now I gotta say, tese two awe so coow! Battleheawt adopted five foaws when tey gots nowhewe to go! He is a supew coow guawd who know how to change diapees, and cawe fow foaws wike no daddy out thewe. He does tis cute ting with ta diapees, making suwe he pouws foaw powdew on ta diapees and ovew ta rump and is so much tat ta foaws gots foaw powdew expwoded evewywhewe! Is so funny!”

Many of the ponies in the crowd cheered as Battleheart’s face turned a deep red and he scratched the back of his head.

The alicorn baby, meanwhile, turned her attention to the bride. “Mowning Dew is a vewy good mawe. We tawks awot at pawties, and she wikes to pway with my son Bucket Bwidwe. She is kind and vewy genorous, hewpin ta pweschool with hewpin pay fow a pwaygwound. I wuv pwaygwounds, tey so much fun, especiawy ta sandbox! I wememba when Mownin Dew was a foaw and she wuv puttin sand in hew diapees...dun know how I wememba tat…”

Morning Dew giggled as the crowd started to laugh, just as Celestia raised her hooves showing off her padded front as she exclaimed. “Now, I tink is time to say ya ‘I Do’s’. So, Mowning Dew, do ya take Battweheawt as ya husband?”

But a blast of light exploded as Luna suddenly appeared right next to Celestia and exclaimed! “Nuh uh! Is my tuwn to say some stuff and ask tat!” She turned to Battleheart. “So tis guawd is coow, he hewps Cannon Feathew to use ta potty and does awot of wowk with his own foaws. He ta numbew one dad eva! One time he was wate to his shift and he had diapees on his head and foaw powdew aww ovew him. My son Cannon Feathew cawwed him ta diapee monstew cause of tat.”

Battleheart slammed a hoof to his face as Luna turned her attention to Morning Dew and exclaimed. “Now fow tis wovewy mawe, she so fun! I did some dweam wawkin and found hew thinking of being a foaw hewsewf! She such a cutie, waning to pway with Battleheart’s foaws. She even had a dweam whewe she was a foaw at tis wedding!”

The crowd roared in more laughter as Morning Dew was now getting embarrassed and whispered. “Can we skip to the ‘I do’s’ please?”

Luna bounced on her thick, padded rump, making it crinklequite loudly. “Yep, is my tuwn. So, Mowning Dew, do ya take Battweheawt as ya husband?”

Celestia stomped about, throwing a tantrum. "Nah uh, I was supposed ta say tat! Ya stowe my wines!”

Luna turned and shouted. “Ya did tis wike a hundwed times fow ta wast thousand yeaws! I wana do it!”

The princess of the sun snapped back. “Nuh uh, I wana do it! I was asked and ya wasn’t!”

Soon the two foal started bickering and Morning Dew snapped. "Hey you two, stop fighting this instant! Or I’m going to tell Twilight! I don’t think she’ll be happy to hear you snuck out of the castle.”

The two foals stopped in their tracks, terrified of what Twilight would do in her new alicorn body if she caught them like this. They both whimpered. “Yes, Mrs. Mowning Dew.”

The mare continued. “Now, you two can share your lines. Don't fight on our wedding day."

Celestia crossed her hooves and growled. “So who goes fiwst?”

Morning Dew and Battleheart looked back at each other as Luna saw an opportunity and declared. "I go fiwst! Battweheawt, do ya take Mowning Dew as ya wife?"

The stallion blushed as he whimpered. "I do."

Celestia got a little flustered again and stomped about in frustration. "Is my tuwn now! So, Mowning Dew, do ya take Battewheawt as ya husband?"

Morning Dew turned to face the stallion and stared deep into his eyes as she whispered. "I do."

The two princesses squealed in delight as they raised their hooves and exclaimed. "Ten ya is husband and wife, kiss!"

The couple blushed as they came together and kissed each other, holding each other in their embrace.

As everypony in the crowd clapped and cheered, Luna turned to her sister and whispered. “Otay, time to go back befowe Twilly finds out wewe gone."

Celestia, however eyed the seven layer wedding cake on the table, adorned in white frosting with pink icing outlining every layer. The foal's mouth began to drool. "C...Can I have a wittwe bit of cake befowe I go?"

Luna tried to stop her sister, but it was too late as she disappeared in a puff of smoke and appeared in the middle of the cake! Pieces of said cake rained down on the ponies in the crowd! They were all quite surprised at seeing Celestia take big globs of cake and shove them into her mouth!

Luna teleported herself right next to her sister and babbled. "Ya can't do tis! Ya wuinin' ta weddin'!"

Celestia just grabbed more of the cake with her hooves. "I sowie, but is too good! Ya gots to twy some!" She slammed a hoof full of cake into her sister's mouth who suckled on it.

Luna exclaimed with eyes wide! "Oh, is so good!" They soon both began giggling and shoving pieces of cake into each others mouth, getting quite messy.

The crowd of ponies just dawwed at the scene as wedding photographers took dozens of pictures.

However Twilight suddenly appeared with her face a deep red from frustration. She stomped over, shouting "Celestia and Luna, you get your flanks over here this instant! I can’t believe you did this!" They both whimpered, slowly fluttering over to Twilight as she strapped them down in a stroller. "You two are in so much trouble when we get back to the castle! How many times do I have to tell you two not to wander off and cause trouble?!"

Everypony at the wedding was quite surprised to see the grayish-purple coated alicorn in all her pink apron glory, and everypony around instinctively bowed. Twilight exclaimed as she threw up her hooves. "I'm not actually a princess! This is just Discord's magic at work, like it is with Celestia and Luna."

Battleheart slowly walked over to Twilight and replied. "Um...I don't mean to pry but uh...don't punish them too much, they meant well."

Morning Dew ran over and chriped. "Yeah, they were just so adorable and made this wedding quite memorable."

Twilight gave a long deep sigh as she grumbled. "Well they won't be punished too severely. But they still snuck out of the castle, took over your wedding, and ruined your cake. I can’t overlook all of that."

Morning Dew waved a hoof. "It's just a cake, we can get another one. And after you’ve properly punished these two cuties and set them down for a nap, why don't you join us for the wedding? We’re going to be partying all day and into the night. You could use a break."

Twilight looked over the foals, making sure they were strapped into their stroller as she responded. "I'll see. I might be too busy with these foals to do more than just swing by, though."

Battleheart came over and whispered. "Do you need any help? I have a lot of experience with foals now, and I could be useful with foal sitting if you need it."

Twilight turned and shook her head. "No, it’s fine. I have to do this on my own according to Discord's stupid bet," She then rose and turned to the couple. "Congratulations on your wedding though, I hope your day gets a lot better."

They both nodded and watched as Twilight walked off, strutting out of the wedding. Battleheart sighed. "She really is struggling with those foals I hope she's going to be alright."

Morning Dew nuzzled her husband and cooed, "Oh, she'll be fine, now come on let's go and enjoy the rest of our wedding." And the newly weds kissed each other one more time.

Chapter Four: How NOT to be a noble

After the wedding, a week flew by quite rapidly for the princess and for Twilight (who had to get used to being an alicorn). Twilight slowly woke up one early morning to see that the sun was already rising. Clumsily throwing a wing over her face to shield her eyes, Twilight gave a long sigh knowing that Celestia was raising the sun without her permission again. She grumbled irritably as she slowly stretched her hooves and noticed her body was quite larger than it was before. Her wings were larger, stretching across the bed. She as quite stunned and squeaked upon looking down to discover that her crotchboobs were huge. “What's going on?! How did I get like this?!”

The transformed mare quickly got up and squeaked as she looked at her reflection in a mirror! She saw that she now had a long flowing mane and tail like Celestia and Luna. And she turned to see that her cutie mark had changed as well. It was now a foal bottle with her old star cutie mark on it. The mare rubbed a hoof down her face and sighed. “Looks like I've officially become a mother alicorn, ugh. This is going to be a long month, but I guess I should’ve expected something like this.”

Still quite frustrated over her change in appearance, Twilight turned to the milking machine that Cadence gave her and sighed. “I read how to use that thing even though I hoped I’d never have to. Still, it says natural breastmilk is quite healthy for young foals. It’s not like I can contact Celestia and Luna’s mother and ask her to do it, I don’t know where she is or what happened to her”

Twilight reluctantly took the milk pumping machine and attached the pumps to her teats as she let it run. Then she took out the book and began to read it again going over the portion about breastmilk. After filling two foal bottles with her milk, she walked through the halls of the castle and entered the nursery for the baby alicorns.

Celestia and Luna were already up, shouting across from their cribs at each other in their cute and saggy diapers. Apparently it was something about one of them stealing the other’s teddy.

But Twilight was not in a very good mood this morning due to the recent developments, so she immediately shouted. “You two, stop fighting this instant! It's way too early for this! And what did I say about trying to raise the sun and the moon without my permission? Do you want me to spank you?”

The foals squealed in fright as they turned to see that Twilight was looking more like an alicorn with her long, wavy mane! But Celestia then gaped in awe as she babbled. “Oh my me, ya wook wike me befowe I tuwned into a foaw awong side Wuwu!”

Luna also nodded and babbled. “Yeah, ya weawwy do wook diffewent, awmost wike ouw mama. Is Discowd doing tis to ya?”

Twilight shrugged and responded. “I’m assuming he is, but it isn’t going to stop me from caring for you two, and putting you in time out for being naughty. If you keep acting up like this you’re going to force me to take extreme measures,” The mare then gave each foal the bottles of her breast milk. “Here you go, sweethearts. You need to grow up big and strong.”

The princesses squealed in delight as they took their foal bottles and started to suckle down their milk down, making cute noises as they did so. It was quite adorable watching them down their bottles and Twilight cooed, “Oh you two love my milk, don’t you? Yes you do!”

The two foals squeaked at what they heard and started to suck down the milk even more, even though they were surprised to learn where it had come from. Afterwards, Twilight took them and quickly changed their soggy diapers, not wanting to risk a rash as she couldn’t be sure how long they had sat in them.

Twilight worked quick as a flash, having gotten used to diaper changes by now. With practiced precision she untaped the diapers of the foals and wiped them down thoroughly. Then she used her magic to instantly poof new diapers around their rumps with her cutie mark on the padding, sprinkling in a helping of foal powder for each. She then took the two to the kitchen and started to spoon feed them foal food mixed with oatmeal, while going about cooking an actual breakfast for herself.

Celestia and Luna were amazed as they watched Twilight make a couple pancakes and eat them , all while continuing to spoon feed the foals.

Suddenly, however, the doors burst open! Twilight turned to see Fancy Pants enter the castle and her eyes went wide as she tried to warn him. “Don’t come here! I’ll come to you!”

Alas the warning was too late for Fancy Pants to hear as he entered the castle, and slowly turned into a foal. His fancy suit turned into a suited onesie as a thick, light blue diaper grew between his legs. Luna and Celestia both guggled in excitement while Fancy Pants’ face flushed red. He shoved his hoovers over his diaper, squeaking. “Wha happened to me?! Why I get tuwned into a foaw?”

Fancy Pants started to tear up and began to wail. But Twilight, thinking quickly, teleported him into a highchair that had materialized for him, then she started to spoon foal food into his mouth. “I’ll have to put up a sign outside to explain that only foals are allowed to come in here,” She sighed in realization. “So you’ll be a foal at least until you leave the castle. From the looks of it, even younger than the princesses."

Fancy Pants was still quite embarrassed at being in a thick and literally fancy diaper, as well as a baby blue suited onesie. He scrunched the padding between his legs and asked. “So uh...since ta pwincesses awe babies, we needs somepony to hewp with some of ta othew stuff. Ta othew nobwes didn’t wana deaw with it so tey made me come hewe.”

Twilight dawwed as she hugged the baby foal and nuzzled him. “You did that? What a selfless thing to do. And you’re so cute! At least now you can warn other ponies so they won’t come into the castle by accident and get regressed again. I don’t wanna have to run a day care service, the castle’s way too big to take care of foals," She snuggled the little colt, then took what had been a briefcase full of important documents. It was now a saddle bag full of reports and complaints on construction paper, written in crayons.“It looks like Discord's magic transforms anything that enters the palace into foalish stuff," The mare then placed the squirming Fancy Pants into a playpen to let him play with the princesses. "Now you three play together nicely and don't cause any trouble. I have business to attend to, including a sign that should’ve been put up a long time ago."

Fancy Pants gulped upon seeing the regressed princesses across the playpen. He Kicked about nervously and whimpered. “Uh...h...hi… P-pwincesses.”

Celestia giggled as she waddled over and poked Fancy Pants's diaper bulge. “So, Fancy Pants, awe ya gonna be called Fancy Diapee now?” She teased with a smirk.

Fancy stomped about in his padding and shouted. “Nah uh! No way ya gonna caw me tat! I stiww Fancy Pants!”

Luna scratched her head and asked. “Ya suwe? I mean most foaws dun weaw pants, so I bet ya mommy cawwed ya Fancy Diapee as a foaw.”

The stallion started to get more angry as he started to throw a small tantrum and whined. “Nuh uh! My mommy made me weaw cute ovewawws as a foaw, kind of wike tese,” The foal’s little tantrum made his padding crinkle quite loudly and poof out large clouds of foal powder. He squealed as his onesie then popped open, revealing the super thick, fancy, light blue diaper which had gold crowns printed on it. The padding poofed out from under his rump.

Celestia put her hooves over her mouth and snickered. “What if we caww ya Diapee Pants? Because you not weawin pants with tose big diapees, and no way ya making it to the potty wike that.”

Luna was bouncing up and down and exclaimed. “Yeah tat sounds wike a bettew nickname, Diapee Pants! Ow ya wather be cawwed Potty Pants cause ya gonna potty in ya diapees!”

The former stallion shouted. “Nah uh! Ya bettew not caww me Diapee ow Potty Pants! Ya two being meanies! I dun make fun of ya fow being foaws, do I?!” He waddled off, shaking his big, blue diaper and went to play by himself, taking some crayons with which he started making some doodles.

Celestia and Luna were silent as they watched their new regressed companion waddle off. Both felt a little bit bad now about the teasing, realizing they had gone a bit overboard. So the princess of the sun turned around, trotted over to the regressed stallion, and told him. “Hey, Fancy Pants, we sowie fow teasin’ ya.”

Luna chimed in. “Yeah, we sowie. We didn’ mean to make ya cwy. We can hewp ya make ta most out of being a foaw.”

Fancy Pants turned around and grumbled. “Wee if ya sowie ten hewp me with my onesie. I dun wike my diapee being exposed.”

Celestia and Luna both waddled over and helped with the little colt’s onesie, trying to snap the buttons together. But it seemed too hard as they tried using their hooves and magic to no avail. Fancy Pants was getting a bit embarrassed with the princesses messing with his onesie and eventually grumble. “Awight, stop tat! Ya did ya best. I guess it not gonna cwose up.”

The princesses both stepped back and plopped on their own padded rumps as Celestia asked. “Okay, but why did ya come hewe? Ya must’ve known ta wisks.”

Fancy Pants didn’t bother to look up from his doodle as he explained. “I did tis beacuse ta west of ta nobwes wewe too scawed, awfaid tey’d tuwn into foaws. I knew ta wisks and didn’ cawe, I had to see if it is was twue tat you wegessed. And ya did."

Luna hugged him and nuzzled the colt. “Weww tat makes ya a weawwy bwave cowt. Ya my favowite nobwe.”

Celestia bounced on her crinkling diaper, making foal powder poofed out as she babbled. “Fow being so bwave and being my favowite nobwe too, I gonna give ya a supew fancy diapee!"

Fancy Pants prodded a hoof into his own padding, making it crinkle quite loudly again. "I aweady weawin a fancy diapee! Wook at it, is so poofy and big! It wooks wike a big, bwue couwd!”

But Celestia just waddled over and started untapeing his diaper, ripping off the tabs and making it drop as Fancy Pants blushed and squeaked. “Hey, wha ya doing?!”

The little baby alicorn rolled her eyes. “I’m giving ya a fanciew diapee, now cawm down and wet me wowk!” She then went about taping the little colt up in a diaper with a sun printed on it the padding. “Thewe! Now ya got ta bestest fancy diapee eva!"

Fancy Pants kicked about in his new diaper and babbled. “I guess is nice, and is soft. Awso, it makes me feew wawm, I wike it!”

Celestia hugged Fancy Pants again and nuzzled him as she flapped her wings and squealed, “Yay! I so happy ya wike my diapees, tey ta best ones eva!”

Luna crossed her hooves and grumbled. “No faiw, I was gonna put him in a fancy diapee with a moon on it.”

Fancy Pants blushed and scooted backwards a little, not wanting a third diaper as he babbled. “Tats weawwy not needed, wook I dun need fancy diapees. I stayin’ a foaw onwy untiw I weave.”

Before Celestia or Luna could respond, Twilight came over with a smile on her face as she placed a bunch of other pieces of construction paper into the colt’s saddlebag and cooed. “Well, Fancy Pants, you’ll be happy to know that I looked over the forms and gave responses to each issue.”

Fancy Pants squealed as he bounced up and down on his diaper, making it crinkle and making foal powder fly everywhere as he exclaimed! “Tank ya so much! I so happy tat tis is gonna get resolved!”

However, Twilight eyed the colt new diaper and asked. ”What happened to your old diaper? Celestia, did you change Fancy Pants’s diaper?”

Celestia gulped as sher nervously fessed up. “Yeah, I changed his diapee. I wanted to give him a mowe comfy diapee fow being my favowite noble.”

Twilight chuckled. “Oh, well you did a pretty good job, thank you. But it really wasn’t necessary, he’ll be turning back to normal in just a few seconds,” She picked up the colt with her magic. “Come on, let’s get you out of the castle and back to your grown-up self.”

But when Fancy Pants was lead outside, he squeaked as he didn’t turn back to normal and stayed in his shrunken state. “Wha...why didn’t I tuwn back into a aduwt?!” He blinked.

Discord appeared and snickered. “Oh, was I not clear before? Only foals and their caretakers were allowed into the castle. Since you chose to ignore that rule, you’re going to be a foal for a month. At least you can serve as a warning to others who don’t listen. It’s my game and you have to play by my rules. Failing to do so gets you penalized.”

Fancy Pants stomped about as he threw another tantrum and whined. “Tat’s not faiw! I didn’ know I was gonna be wike tis fow a month! Me no wanna be in diapees aww month wong!”

Discord ignored Fancy Pants and instead turned to Twilight with a smirk on his face, seeing how his magic has transformed her as he snickered. “Well, it looks like you have officially become the Princess of Motherhood, Twilight. And from the looks of it, you now have another young charge to care for.”

Twilight blushed and waved a hoof as she replied. “I’m not sure if I want to care for three foals. Two are already almost more than I can handle on my own.”

But Discord only laughed and exclaimed. “Too bad, Fancy Pants broke the rules and must be punished! So for next time, Fancy Diaper, you tell your noble ponies not to enter the castle!” He then snapped a claw and disappeared in a puff of smoke.

Fancy Pants crossed his hooves and plopped down on his crinkling pampers as he grumbled to Twilight. “Ya bettew not stawt callin me Fancy Diapee ow othew embawassing nicknames. I stiww Fancy Pants, got it?!”

Twilight cooed. “Oh, don’t worry. I’m not going to call you nicknames like that. But it seems I’ll have to care for you since I doubt anypony else is going to be up to the task, and I don’t want you getting into trouble,” She then took out a stroller and strapped him in along with the baby alicorns (which she had teleported to her location) as she cooed. "Alright cuties, let's go out and see what the ponies of Canterlot need. Just remember not to wander off, and to ask me if you need anything."

Twilight pushed the foals in the stroller along through Canterlot as Fancy Pants giggled and kicked his padding. He was quite nervous about what was to come though, already dreading the stares and coos.

It took a few hours for Twilight to make her way around Canterlot while pushing the stroller with the three foals around. The newly fully grown alicorn was getting a lot of attention with many more ponies bowing to her even though she had already tried to tell them not to. Despite it being annoying, Twilight continued along (with Fancy Pants helping her navigate through the streets), she went from house to house in the city, talking about the various issues as they had been brought up in Fancy Pants’ reports.

The little colt himself was feeling quite embarrassed as he met many of the nobles he’d known as an adult. They in turn thanked him by ruffling his mane or telling how cute he looked.

The princesses, however, were starting to get a little jealous upon seeing that Fancy Pants was getting all the attention. Celestia eyed the colt and grumbled. “It not faiw! He gettin aww tat attention and we noting! He a gweat pony but we pwincesses! We outwank him!”

Luna nodded and responded. “Yeah, and did ya see Nana Twiwy? She pwaisin him wike he’s hew son ow somethin. We wewe foaws fwist!”

The princess of the sun then bent down to ear level of her sister and whispered. “Wets puww a pwank on Fancy Pants. Maybe we can make him do somthin embeawssin in fwont of his wife, Fweuw.”

Luna was listening closely and nodded in agreement. “Yeah, tat sounds wik a fun idea! But what we gonna do? Is gotta be good!” The two waited and pondered as they watched Fancy Pants bouncing on his padded bottom, loving the attention he was getting.

The group eventually did make their way to Fleur’s and Fancy Pants’s manor. It was quite big with Fancy Pants’s eyes growing large upon seeing it as he shouted. “Wow! Is so much biggew ten I wememba it being!”

Twilight looked down at her little foal and cooed. “Well, seeing that you’re a foal now, it may appear to be larger than it is. Now, are you ready for Fleur to see you like this?”

The little colt crossed his hooves and grumbled. “She’s pwobabwy gonna just make fun of me and tease me.”

But Twilight still went up to the door and knocked on it. It opened to reveal a lovely, tall unicorn mare who was quite surprised at seeing Twilight as an alicorn princess, and her husband as a little foal in a cute, thick diaper, trying desperately to hide his padding with his hooves.

Fleur clapped her hooves, came over to the little colt and picked him up in her magic and hugged and nuzzled him while cooing. “Oh, he’s so adorable! I never dreamed you’d become a foal, darling!”

Fancy Pants kicked about in his thick padding and whined. “Stop tat! Ya embewassin me, Fweuw!” But Fleur didn’t stop cooing at him, instead nuzzling his chubby belly and making him kick about in his thick diaper while babbling uncontrollably.

Celestia and Luna laughed, flapping their wings and clapping their hooves while Twilight just dawwed as she replied. “He is so adorable. But I’m afraid he’s like that for a reason. He accidently entered the palace and was turned into a foal, so he’ll be stuck like this for a month.”

Fleur sighed as she placed him back in the stroller. “Well, he’s such a brave little colt. We didn’t know that such a thing would happen. Everypony was quite scared to enter the palace after Discord showed up in it.”

Twilight bent her head down. “I should've seen this coming and warned him sooner. I could’ve sent word out.”

Fleur looked up and asked. “It couldn’t be helped, at least now he can serve as a warning to others. I apologize, but could you please watch him for me? I would love to but seeing as he’s a foal now, I have to pick up his work in keeping things going here. Also our house doesn’t have the accommodations for foals, and it would be pointless to waste money converting it if he’ll just go back to normal in a month. We’re not looking to raise foals just yet.”

Twilight groaned, rubbing a hoof through her mane as she grumbled. “Fine, I'll care for him. This won’t cost you a thing.”

Fleur smiled as looked down at Fancy Pants and asked. “Now, darling, can you be our little emissary for the nobles to Twilight?”

The little colt raised his hooves and exclaimed. “Yes Fweuw! I’ww still hewp in keeping tings wunning in Cantewot, ya can count on me!”

Fleur then saw an opportunity and started tickling the colt’s belly, making him kick and squeal about.

Fancy squeaked as a loud hissemanated from him with the white padding turning yellow, and the suns printed on the front began to fade. Fluer dawwed and ruffled his mane. “What a little cutie. If I had diapers I would change you, Fancy Diaper.”

The colt whined, kicking about in his soggy padding as the princesses laughed even more. Twilight then lifted the little colt up with her magic. “Oh, don’t worry, Fancy Diaper, I’ll get you all nice and changed. We wouldn’t want you to get a diapee rash, would we?” She went about placing him down on a mat and started to change the little colt.

As Twilight and Fancy Pants were distracted by the change, Luna whispered to her sister. “Wooks wike he embeawssed himsewf. He weawwy is wike a wittwe baby.”

Celestia gave a nod and babbled. “Yeah, wooks wike he is, but now he gonna wive with us. We can puww eevn mowe pwanks on him. Wike dwawing on his diapee ow putting too much foaw powdew on him.”

Twilight then placed the freshly changed Fancy Pants back in the stroller and strapped him in as she asked. “You comfortable, Fancy Diaper?”

Fancy Pants was quite angry as he snapped. “Stop cawin me Fancy Diapee, my name is Fancy Pants! Ya pwomiced, Twiwy!”

Fleur chuckled. “Well with that giant diaper you can’t even wear pants, so Fancy Diaper suits you.”

Fancy Pants glared at his wife and whine. “Fweuw, stop tat, sewiouswy! Ya weawwy being a meanie!”

Twilight waved a hoof. “Oh, we’re just teasing you, don’t get all serious. There’s no need to be such a poopy head.”

Fleur cooed. “It looks like the little one could use a nap, he seems quite cranky.”

Twilight responded. “Yeah it seems so. I’ll make sure he gets a good nap, and if you need anything or want me to bring Fancy Pants over just send me a letter. I’d rather not have another pony get turned into a foal, thank you.”

Fleur blushed and responded. ”Right, I’ll keep that in mind. I’ll start passing word along, and if I learn of any good nannies I’ll send them your way.”

Twilight then pushed the stroller away with Fancy Pants poking the thick diaper between his legs as he mumbled to himself. “I wana weawn how ta use ta potty and get out of diapees! Tat way nopony gonna caw me Fancy Diapee ow Diapee Pants again!”

Twilight eventually took the foals back to the castle and to the nursery. There she placed Celestia and Luna in their respective cribs, both of whom already sleeping soundly. The mare slipped pacifier in their mouths and watched them suckling and fidgiting. She dawwed at seeing how cute the foals were being.

She then took Fancy Pants, seeing him kick in his padding and was unsure of where she would put him and sighed. “The princesses will get jealous if I put you in either crib and they’ll probably fight each other again.”

Twilight decided to take the little colt cover her back and went straight to her bedroom. When she got there she laid down into her bed and drifted the little colt into the pocket of her underbelly.

Fancy Pants curled up next to her, trying to get warm. He seemed so fragile and cute kicking about a little in his diaper. He then did something unexpected as he latched onto one of Twilight’s crotchboobs and began suckling her breastmilk. Twilight paused as she felt a little jolt from the unexpected motion, unsure of what to do. But when she saw how content the little colt looked she decided to let it go. She didn’t want to wake him knowing he’d probably cry and wake the other foals.

So Twilight just watched him suckle her milk as she drifted over the book Cadence gave her and began reading the section about baby colts and how to care for them.

Chapter Five: How NOT to be big sisters

Celestia and Luna both woke up in their cribs in their soggy pampers after their nap. They both looked at each other with tired and grumpy expressions on their faces. Celestia slowly raised herself using the bars of her crib, revealing her adorable diaper slightly yellowed as she turned to her sister and yawned. “Hey, ya wana go see whewe Fancy Pants is? I bet he sweepin with Nana Twiwy.”

Luna also nodded in agreement as she babbled. “Yeah, it not faiw tat he gets to sweep with hew! She ouw nana fiwst!” They both flew over the cribs and waddled off down the hall shaking their thick, soggy pampers back and forth. The two headed straight towards Twilight’s bedroom and squeezed through the door which had been left open slightly ajar.

both looked up to see Twilight Sparkle lying in the bed with Fancy Pants nuzzled into her underbelly, the foal suckling onto her teat, seeming to be so happy and peaceful. The two princesses both got even more jealous seeing that Fancy Pants getting to sleep with Nanny Twily and drink her milk.

Celestia crossed her hooves and bounced on her padding, making it squish between her legs as she babbled quite angrily. “Is not faiw, he gets to sweep with Nanny Twiwy and we dun.”

Luna nodded in agreement as her tummy grumbled and she gave it a few pats. “Yeah, I hungwy and want Nana Twiwy’s miwkies.”

The two foals both fluttered onto the bed and waddled over to Fancy Pants, who turned his attention to the baby alicorns. The stallion got up on his soggy pampers too, making them squish beneath his rump. Eyeing the princesses he babbled. “What ya twi doing?”

Celestia crossed her hooves with a pout on her face as she grumbled. “Ya not gonna have Nana Twiwy to yasewf, tat not faiw.”

“Yeah, ya gotta shawe hew, is not faiw ya gets to sweep with hew!” Luna shouted at Fancy Pants in anger.

Fancy Pants rolled his eyes and babbled. “I not hoggin’ Mama. I tink tat ya two just jeawous and ya wants to buwwy me. But I dun cawe.”

Celestia blushed as her tummy grumbled and she scoffed. “Nuh uh, we not gonna buwwy a. We just want Nana Twiwy’s miwkies. We hungwy and she sweeping too wong!”

Luna was getting quite flustered as she shouted. “Yeah, ya bettew not have dawnk awe hew miwk!”

Fancy Pants got up and whined. “I didn’t! Go ahead and dwink Twiwy’s miwkies. She neva wuns out.”

The two princesses slowly came up to the big alicorn, and each of the baby alicorns took ahold of one the teats of Twilight and the two slowly began to suckle her milk. The mare squeaked as she felt the sudden jolt of the foals suckling milk from her, which roused her from her sleep. Still she turned to see the two babies with a soft smile and dawwed. “Aww, someponies are hungry. That’s so cute. Go ahead and drink up, there’s plenty of milk for both of you.”

The newly created alicorn then laid back down, humming as she fed her charges while she took out her book and started to read it. The mare then turned her attention to Fancy Pants who sat there with a pout and had crossed his hooves. Twilight blushed and asked him. “Did you get enough to drink too, little Fancy Pants?”

The little colt nodded and looked up as he babbled. “Yeah, I did. Tey needed miwkies too so I otay.”

Twilight sighed having a feeling that the fillies forced the little colt off and asked. “Let me guess, they kicked you off?”

Fancy Pants grumbled. “Yeah tey did, tey jeawaous tat I swept with ya wast night,” Twilight just chuckled as she levitated Fancy Pants in the air and hugged him in her hooves. He rubbed his hooves over the mare’s face as he babbled. “Ya a good mama. I wove ya.”

The mare then gave his soggy pampers a few pats and giggled. “Oh my, you’re so soggy. I guess I should change your diaper before you get a rash,” She went about changing the colt’s diaper and mmmphed feeling the little fillies suckling on her teats quite roughly. “Hey, go slower.” She mumbled.

The two fillies did as Twilight asked suckling the milk quite slower while the mare continued to finish Fancy Pants’s change. She took off his diaper and went about wiping his rump clean. She then went about giving his rump a good showering of foal powder, and finished the change by strapping the colt into a new, fancy looking, light blue colored diaper.

Afterwards, Twilight took the baby princesses and went about changing each of their diapers as well as she commented. “You foals are quite heavy wetters, I might have to tape you all up in double padding at this rate. Can’t risk having you leak through and wet the bed.”

The two regressed princesses blushed, quite embarrassed at being called heavy wetters as Twilight finished up the diaper changes for them. After the double change she went about taking the fillies over her shoulder, patting them on the back and thus having them spit up. After cleaning up from that, she placed them down and got a bit stern as she asked them. “Now Celestia and Luna, were you two being mean to Fancy Pants earlier?” The foals both blushed as they looked in shame. With a harsh glare Twilight scolded. “Fancy Pants is younger than you two, so that means he is your younger brother. You two need to be nice to him. Is that clear?”

The two princesses both slowly nodded and mumbled. “Yes, Nana Twiwy We sowwy.”

The mare then levitated the foals onto her back and then placed them in a playpen as she cooed. “Now there’s a lot I have to do today so I need you three to be on your best behavior. Alright?”

The foals all nodded as they babbled. “Yes nana Twily.” Twilight then went to a couch she had set up in the courtroom which was now a glorified nursery and play area filled with foal toys, plushies, and a playpen with a pink fence surrounding the area.

Not long after being placed in the playpen, Celestia waddled over to Fancy Pants, who was busy playing with foam blocks, and asked him. “So Fancy Pants, ya wana weawn how ta use ta potty again?”

The stallion smacked the blocks in excitement and went about bouncing on his pampers, poofing out big poofs of foal powder as he exclaimed! ”Yeah! I dun wan be cawwed Fancy Diapee ow Diapee Pants any mowe! Whewe’s ta neawest potty?”

Luna waddled over and babbled. “I tink tat we can use one of owa toiwets tat used ta be owa thwones.”

Fancy Pants giggled putting his hooves to his face as he babbled. “Tey stiww awe, tey ta pocewin thwones!”

The two fillies burst into laughter, rolling around on the ground at the joke. Fancy Pants rolled his eyes and looked over at Twilight, who was going about writing reports and appeared to be unaware of the foals plans. The colt tapped a hoof to his chin and bounced on his diaper making foal powder poofed out as he babbled. “I guess we gotta do it whiwe Twiwy is busy, but we might get in big twoubwe when she notices we gone.”

Celestia waved a hoof. “Nah uh, ya gonna be fine! Now come on, wets go! Ta soonew ya get potty twained, ta fastew ya gonna be outa diapees!”

Fancy Pants was hoisted over the playpen and he and the regressed alicorns waddled past an uanware Twilight. Fancy Pants was led down the hall to the throne room where the pink and purple colored toilets stood. The colt got quite nervous looking up at the toilets, noticing that one had Celestia's cutie mark on it while the other had Luna's. They were quite big compared to the foal and he was starting to get scared. What if he fell in?

Just then, Fancy Pants heard strange gurgling noises from the toilets and he started to smack his thighs against his padding as he asked. "C...Cewestia wha is tat noise?"

The princess of the sun snickered behind a hoof. "Oh, is just ta potty monstew. I heawd tat he wuvs to eat foaws tat dun know how to use ta potty. But ya gonna be fine, ya got us to pwotect ya," Then she instructed. “Now come on, take ya diapee and we hewp ya get on big potty. Ya can use mine.”

Then, suddenly and without warning, the top of Luna's toilet slowly opened up! It revealed rows of sharp teeth on the bottom of the lid, which now looked like a mouth. Celestia’s eyes went wide eyed and she squeaked out in fright! “Oh my me! Tats ta potty monstew, wun!"

The toilet reared up, snapping at the foals before slamming the lid and smashing it against the seat as toilet water spouted outwards. Celestia gulped as she scrunched her padding between her legs to avoid getting splashed, and she babbled. "Uh… Wuna, ya can stop now!"

Luna waddled over, scratching her head. "Wha ya tawkin about? Me not do anythin." She also looked up and gasped upon seeing the toilet as it roared, spouting out more water outwards as it began bouncing towards the foals! They all ran off as fast as they could from the potty monster!

They ran back toward Twilight as fast as they could, all the while the giant toilet kept slamming the lid and shouting in a scratchy voice! "I'm gonna eat you! Foals are my favorite meal!"

The foals screamed in fright while waddling away in their crinkling diapers! Soon they slammed right into Twilight’s lap, making her squeak in surprise. She looked down at the foals and asked in confusion. “Huh? What’s going on?!”

Fancy Pants raised his hooves, showing off his adorable padding as he babbled. “Nana ta potty monstew is coming! Ya gotta save us!”

Celestia turned to Twilight and was bouncing in her padding on Twilight’s lap as she cried out. “Yeah! Wuna and I wewe pawying a pwank on Fancy Pants, but ta potty is actuawwy awive!”

Twilight looked up and saw the toilet monster snapping its jaws. It made her roll her eyes and grumbled, “Discord seriously!?”

The dracquinous then suddenly appeared in a puff of smoke with him laughing. “Sorry, I just couldn’t help myself when the princesses set up that little prank for Fancy Pants. Decorating the toilet to look like a foal eating monster, hilarious!” He quickly snapped a paw, and the toilet returned to normal and teleported away. “There, I put that ‘throne’ back where it belongs. You’re welcome. But you’re not getting anymore favors from me.”

Twilight eyes glared at the baby alicorns. “Seriously?! I can’t believe that you would do that to Fancy Pants! What, were you going to try and flush him too?!”

The two alicorns looked down, feeling quite guilty and they both started crying. “We sowie, Twiwy. We wewen’t gonna fwush him, honest. We wanted him ta get out of diapees, bu we wanted to have a wittwe fun with him fiwst.”

Fancy Pants blushed as he waddled over, making his adorable diaper shake about as he hugged the little fillies, nuzzling them as he exclaimed. “I not mad at ya! Tat was a funny pwank, ya two! Ya wucky ya got ya own, custom big potties instead of bowing, owd white ones,” Then he looked up at Twilight with puppy dog eyes and whimpered. “Hey Twiwy, dun punish tem. Tey just twying to hewp me. I ta one who wanted to use ta potty.”

Twilight dawwed before she rubbed a hoof across her mane and sighed. “Alright, I guess I can let it slide. But you two better stop being mean to Fancy Pants. And please don’t ever go near those toilets or any others without me, I don’t wanna take any chances that something could go wrong!”

Celestia and Luna both blushed and slowly nodded their heads as Discord shrugged. “Guess that means my work is done here. Until we meet again, princess.” He then snapped a claw and disappeared in a puff of smoke.

Fancy Pants waddled over with a blush on his face, his diaper squishing between his legs as he asked. “So uh...Nana, I peed my diapee, can ya change me?” He poked his padding, making an audible squishing sound.

Twilight dawwed again as she picked him up and nuzzled him. “Oh, you’re just so adorable! Of course I’ll change you, Diaper Pants.” She then went about changing his soggy diaper.

After the diaper change, and after a few hours of playtime (and a dinner of Mashed Peas). Twilight took the three foals upstairs and was surprised to see there was a new crib in the princess alicorns’ nursery. Not only that, there was also a closet filled with diapers folded up nicely on top of each other, and a bunch of cute onesies all hung up inside. The princess alicorn giggled. “Oh, that's just too cute! Looks like Discord has your crib all set up, Diaper Pants.”

The mare then settled each foal into their respective crib and slowly tucked each one in under a bunch of foal blankets as she cooed. “Now you all get some sleep and don’t stay up all night, okay?” Twilight then slowly left the room.

As soon as Twilight was gone though, both Celetia and Luna teleported themselves to Fancy Pants’ crib. He squeaked and kicked about as the fillies snuggled the colt on both sides, wrapping their wings over him as he blushed, feeling quite odd about this. He babbled. “Wh..why ya doing tis?”

Celestia nuzzled him and cooed. “We sowie fow aw ta twoubwe we caused ya today.”

Luna nodded and babbled. “Yeah, ya owa wittwe bwuda and we did tweat ya badwy aww day. We pwomice we gonna take cawe of ya fwom now on.”

Fancy Pants blushed as he responded. “Wook, I tink ya two awe funny but how ya gonna cawe fow me? Nana Twily awweady wiww.” But then he squeaked as they went about changing his diaper again, and taping him into two thick, nighttime diapers.

Celestia babbled. “We gonna take cawe of ya when Nana Twiwy can’t.”

Fancy Pants blushed as they nuzzled him and placed their wings over him. “Is gonna be wewid, I was a onwy chiwd as a foaw. I wondew wha having two big sissies wiww be wike?”

Chapter Six: How NOT to host a party

Fancy Pants was quite happy, kicking about in his highchair and munching on his foal food. He turned to his “older sisters” who were busy munching on their food as well. Twilight was using her magic to lift three rubber spoons foal full of big glops of foal food, feeding her charges one by one. As she watched her foals munch on their food and kick about in their cute, thick diapers, she couldn't help but coo. “Oh, you three are so adorable!"

Fancy Pants was quite happy kicking about in his padding and holding his hooves up "I wuv tis so much! I didn tink being a foaw would so fun! Is nice!"

Twilight just loved seeing her new charge being so happy, as she bent down and nuzzled him. "Well I'm happy to see you being happy. You’re definitely not a stinker like Celestia and Luna have been," She then rose up and turned her attention to the three foals. "Now, there's something very important I need to discuss with you," The foals all turned their attention to Twilight as she tried to stay as calm as possible while telling them. "There’s a fancy dinner party in the palace gardens today, and I don't want to be chasing you three around and having you mess it up. So please, can you three stay in the castle and be on your best behavior just for one day? No clogging toilets, no unleashing potty monsters, just behaving like good foals should."

The foals all slowly nodded their heads and were placed in their playpen. Twilight took that as a sign that things were under control, and so she went upstairs to get dressed for the party.

The second Twilight left the three foals all looked at each other with mischievous grins. Celestia turned to her “siblings” and asked. "So how we gonna escape to ta pawty?".

Luna turned to Fancy Pants and crossed her hooves as she babbled. "I tink tat Fancy Pants said he was gonna come up with ta pwan. So wha’s ta pwan?"

Fancy Pants tapped a hoof to his chin. "I dun know. I tink Mama Twiwy put a magic bubbwe awound ta castwe to keep us fwom going anywhere aftew ya two went to tat wedding."

Celesti giggled, putting a hoof to her mouth. "Yeah, tat was siwwy and fun! I wuved ta cake, it was so good!"

Luna bounced on her padded rump. "Yeah! Tey pwoababyw gonna have aww kinds of sweets at ta pawty! We gots to go and twy to eat as much possibwe!"

Fancy Pants nodded in aggremsnt. "I completely agree with tat, I haven’t missed a pawty since I became a nobwe. We need to bweak ta bawwiew awound ta castwe though, tats ta biggest pwobwem. Also if ya get caught again. I tink Nana Twiwy is gonna punish ya. Maybe give ya spankies"

Celestia rolled her eyes and scoffed. "Ya dun tink tat we figuwed out how to bweak mama’s bawwiew. We can do tat. Ya said ya gots a pwan to get us in ta pawty, so wha’s ta pwan?”

Fancy Pants took out a piece of construction paper with a plan written down. “So, I tink tat if one of ya act supew cute and keep Mama busy, the othew one of ya wiww bweak ta bawwiew. Aftew tat I go to Nana Twiwy and teww hew we aww need a nappy and we weawwy twied. So she puts us down fow a nap and weave us awone fow a few houws, giving us aww tat time to sneak out ta window and to ta pawty!”

The foals squealed in delight, all excited to go to the party and bouncing up and down in their diapers. Fancy Pants turned to Celestia. “Ya need to go now and wewase the shiewd! Ya magic’s stwongew.” The princess of the sun nodded as she quickly flew over the playpen and waddled off.

Luna turned to Fancy Pants with a big smile and hugged him as she babbled. “Wooks wike we gotta put on a pewfowmance fow Nana Twiwy!”

The little colt blushed, kicking about in his padding as he nuzzled into Luna. "Otay, wets get going ow we gonna miss ta pawty."

The two then waddled upstairs to Twilight's room. The two foals burst through the door and found Twilight, in a long, flowing purple and pink dress as they babbled. “Nana! We gots a question!”

The alicorn looked down at her foals and cooed. “What is it, darlings? And shouldn’t you two be in your playpen? Do you have to use the potty?”

“Nu-uh, no need potty,” Luna shook her head and then asked. “Nana, why awe ya wooking so pwetty?”

Twilight blushed, feeling a bit embarrassed about being caught wearing such a gown. She squeaked. “Oh, you think I'm pretty?” She looked at herself in a mirror and twirled about in her dress. “I do feel like a princess, but I never thought about being pretty, I was just getting ready for the garden party. They said fancy attire was necessary.”

Luna clapped her hooves and babbled. “Ya wook gweat, Nana! Ya ta pwettiest pwincess eva!”

Twilight dawwed and nuzzled Luna. “Oh, I’m glad you think that way. I know we only have two weeks left, but I'm so happy to be your nanny until then. I can never stay mad at you, your sister, or your ‘brother’."

Luna hugged Twilight's face and nuzzled back as she babbled. "Ya a gweat nana, and we sowie fow cuaisng ya so much twowbe.”

Fancy Pants nodded and responded. "Yeah, we didn' mean ta make tings hawdew fow ya, we just gots aww tis enegwy tat makes us wanna do tings!" He started bouncing up and down on his thick diaper, making adorable crinkling noises and causing poofs of foal powder to come out.

Twilight dawwed and nuzzled the little colt as well as she cooed. "It’s quite alright, it’s expected of foals to not follow the rules once in a while. You and the twins are actually better behaved than most foals, all things considered."

Luna blushed a little at having herself and her sister be referenced as twins. Then she asked Twilight. “So, can ya bwing some cake and cookies home fwom ta pawty?”

Twilight laughed. “Of course, as long as you three keep your promise and don’t get into more trouble. Now how about I give you some lovely milk?” She laid on her bed and both Fancy Pants and Luna waddled over and nestled into the pocket of Twilight’s underbelly. They began to nurse while Twilight watched.

Celestia came waddling into the room shortly afterward, yawning. “Nana, we want a nappy.”

Twilight took the foal into her magic and gently nuzzled her. “Oh, why don’t we all take a nap together? I have some time before the party. Just wake me up if you need anything or if I sleep too long.” She placed Celestia into the pocket of her underbelly as well, who began suckling Twilight’s teats. Satisfied, she lay down and slowly fell into a deep sleep. Nursing always made her feel tired.

The three foals waited until they heard Twilight snoring loudly, before slowly making their way off the bed and plopping their padded rumps onto the ground below. They began to waddle to the door as Celestia babbled. “Ya pwan is wowking Fancy Pants, but how we gonna make suwe we get back befowe Nana Twiwy notices we gone?”

Fancy snickered, taking out a device unfamiliar to the princesses. “I took tis foaw monitow and set it up on hew. So now we keeping an eye on hew instead if it being ta othew way wond. So if she wakes up ow stiws awot I’ww heaw it and teww ya guys we need to get back. And even if she wakes up and tries to wook fow us, we can be back in ta castwe and in ta pwaypen befowe she finds out. She just assume we got wost expowing the castwe.”

Celestia squealed in delight as she hugged Fancy Pants. “Tat sounds wike a gweat pwan!”

Luna nodded in approval. “Yeah it weawwy does, ya so smawt!”

Fancy Pants raised his head in pride. “Wew ya two didn’t make me in chawge of aww ta bowing stuff fow nothin’! Now wets get goin’ we waistin’ time!” And he advised. “And keep ya voices down ow ya wake Nany Twiwy.”

Celestia blushed, looking back at her padding. “Um... I dun mean to sound siwwy, but I dun wana go to a fancy pawty again in just my diapee. Didn’t Discowd put a bunch of fancy foaw cowthes in owa cwoset?”

Luna nodded in agreement. “Yeah wets get pweettied up a wittwe, tat sounds wike wots of fun!”

Fancy Pants looked behind and giggled upon seeing his poofy diaper. "Uh yea, I'ww just put on one of tose suited onesies, and hopefuwwy ta biutton fwap won’t pop open.”

Celestia nuzzled him. “Even if it does ya can count on me ow Wuwu to fix it fow ya.”

They then all went to the nursery to get ready for the party. Celestia took out two frilly dresses and the sisters went about dressing each other. Fancy Pants, meanwhile, dressed himself in the first suited onesies he laid eyes on. But he struggled to button the flap underneath, partially because of his clumsy, tiny hooves.

It didn’t take long for the three foals to dress themselves and Fancy Pants gasped as he turned to see the two sisters coming over, giggling in their pink, frilly dresses. He blushed, scrunching his padding between his legs. “Ya two wook vewy pwetty.”

Celestia came over to Fancy Pants. “Ya wook gweat too. Ta onesie matches ya diapee weww,” She then turned to see that his padding was straining under the button flap and asked. “Huh? Did ya put on a thicker diapee?”

Fancy Pants blushed and shook his head. “I put on two, ya know tat nopony can change us othew ten Twly wight? And with tese dwesses on is not wike we gonna be abwe to use ta potty. The gawden pawty wiww pwobawy have tose scawy big toiwets.”

Celestia gasped at this, realizing that Fancy Pants was right! “Ya so wight! Wuwu we should put on two diapees too. I didn’t tink about potties, and is not wike we can bwing some with us!”

Luna blushed but agreed. She and her sister put on two diapers with Fancy Pants’ help, now they would be protected against leaks. The three then waddled off together down the stairs of the castle. They headed out the back and out into the royal garden.

They eventually came up to a butler that was standing outside to greet ponies. He eyed the three foals. “Uh, what are you three doing out here? Aren't you supposed to be under Princess Twilight’s supervision for the next two weeks?”

Celestia scoffed. “Of couwse we awe, bu she was busy doing woyaw stuff, and she said we can come to ta pawty. We made suwe to dwess up nice and evewyting, now ya gonna wet us in ow not?”

The butler nervously gulped and bowed. “O-of course, go on in and have a good time, little ones. Just try not to make a mess of things.”

The three foals quickly waddled inside and they looked at all the fancy ponies going about their business in the garden proper. Celestia giggled. “Is funny, tey aww scawed of going into ta castwe. But tey dun seem to cawe tat Discowd is stiww awound and can easiwy do stuff hewe too.”

Luna nodded. “Tats why I wanted ta come too, wets see what Discowd is up too. If he twies anyting, we be hewe to stop him!”

The foals waddled off as Fancy Pants was suddenly scooped up by Fleur. “Oh, I had a feeling you were coming, Fancy Pants, darling!” She nuzzled him as the little colt squirmed in her hooves. “Hey, stop tat! Tis is so embeawassin!”

Fleur plopped Fancy down on her lap with a bunch of other mares who dawwed and pinched his cheeks. He sighed. “I should’ve known ya was gonna use me to win ovew ta othew mawes.”

Fleur giggled, ”Oh stop that, let’s just have some fun while this lasts. Besides, it’ll give me a little practice if we ever decide to have foals of our own.”

Fancy Pants eeped at what that would entail! “Wait, Fweuw! Ya can’t change my diapee ow anyting, ow Discowd’s magic wiww tuwn ya into a foaw too! Ya dun want tat!”

Fleur giggled and nuzzled her husband. “Oh you’re just so cute! But alright, I’ll keep that in mind. I guess we’ll have to hold off on potty training you,” She lifted his button onesie with her magic, eyeing the double diapers. “Looks like you came prepared, though, Fancy Pamps.”

Fancy Pants pouted. “Oh no, anothew embawassing nickname!”

Fleur giggled further. “Oh, I think it’s cute. It’s not every day your husband turns into a foal. Let me enjoy the moment, darling.” She and the other mares went about talking and cooing, while Fancy Pants sat there, pouting, unable to do anything.

Meanwhile, Celestia and luna went about getting attention from other nobles who were dawwing as they bent down to talk to the little princessess. The princesses, for their part, just giggled and pranced their little hooves on the heads of the nobles. But it wasn’t long until something went awry as one noble asked. “Why do you both have two diapers? Even for foals that must be quite embarrassing.”

The two foals blushed as they tried to cover their padded fronts with their hooves. But then the nobles squealed as loud taping noises could be heard! They looked behind them seeing that they were now wearing giant diapers. They squeaked further as more mares and stallions began having diapers appear, ripping their pants or poofing out dresses.

The nobles gasped and fidgeted about in their new, embarrassing padding. All the while the foals laughed as Luna shot her magic at the buffet table, turning all the simple hors devours into buckets filled with candy, and Celestia turned the punch bowl into a chocolate fountain.

The nobles gasped at all this foalish stuff appearing, some opting to leave. But a playpen style fence appeared, blocking them off. And the butler before them was now dressed in a clown outfit and a giant diaper.

The foals laughed, shooting their magic at the band playing fancy music, turning them into a bunch of foals babbling and playing on plastic baby toy shaped instruments with flashing lights.

It wasn’t long until the magic reverberated off the walls, hitting every pony inside and turning them all into either toddlers in pull-ups or infants in diapers.

Then all of a sudden a giant pinata shaped as Discord appeared and many of the foals all began trying to hit it! Others, however, went about their business, seeming to be unaware of what was happening. Luna and Celestia clapped their hooves together as they led the charge on the pinata, whacking it with sticks.

As for Fancy Pants, he was now being hugged by Fleur, who had turned into a three year old toddler in pink pair of pull-ups. She was playing tea party with other little fillies, all babbling on about their fancy dresses. It was all quite adorable but Fancy Pants babbled. “Fweuw, did ya notice tat ya is a foaw now?”

The little filly looked at herself. “Weww I stiww owdew ten ya, I thwee!”

Fancy grumbled. “Figuwes, but tat doens’t mean ya get to boss me awound!”

“Yeah huh!” Fleur retorted. “I ta big fiwwy and ya a baby cowt, tat means I in chawge of ya. And since ya hewe, having a tea pawty, tat menas we need to dwess ya up!”

The little fillies all giggled as Fleur went about taking off his onesie and slipped a princess dress on him, then she started applying makeup to his face. Fancy kicked and whined as Fleur smeared lipstick on his face and mascara over his eyes. After she finished, he blushed and tried to hide his face as the other little illies laughed.

All the while the princesses finally ,managed to break open the pinata! But instead of candy a bunch of plusies and teddies came out, making the foals laugh as they grabbed at them.
Discord appeared, shedding his pianta disguise. “Aww, how cute! You’re welcome, little ones. A gift from your Uncle Discord.”

Celestia giggled. “Oh, hey, Dissy. So I guessing ya did awww tis?”

Discord threw his claws up and replied. "Guilty as charged .It was such a boring party and I thought I could liven things up a bit.”

Luna asked him. “So ya gonna change aww tese pionies back to nowmaw aftew ta pawty, wight?”

Discord shrugged his claws. “I suppose so. They didn't break my rules by having a party in the garden. I never said it was off limits. However, I’m assuming Twilight didn’t give you two or your ‘brother’ permission to come?” They both blushed and shook their heads no as he sighed. “Well I guess I'll have to distract her for a bit so you can have more fun.”

Celestia blushed and squeaked. ”Wait, Discowd, dun!” But it was too late! With a snap of his claws Discord disappeared!

Celestia and Luna shrugged as they went off to play with their new foalish friends. Hopefully everything would go back to normal before Twilight realized they’d snuck out.

Twilight woke up a few hours later and noticed that instead of three foals there were dozens of foals! All of them were the guards, butlers and maids Discord had briefly turned into plushies two weeks ago! She saw some colts in tuxedos and some fillies in maid uniforms going about cleaning the room. She then turned her attention to two of the baby guards standing at her door. “What's going on?!” She asked them.

The two padded guards both babbled. “We just doing owa job!

The baby maid was on top of a bookshelf babbled. “Yeah! We just cweanin up ta pwace! Gonna make it squeaky cwean.” She squeaked, before she almost fell off! Twilight quickly used her magic to catch the foal.

Twilight then sighed. “Thanks for your help but you’re foals now, there’s no need to do adult stuff. You could get hurt."

The maid blushed and babbled. "I sowie, we just twying to hewp make ta castwe cwean and safe."

Twilight's eyes went wide as she exclaimed. "Wait! Are you saying that every guard, maid, and butler became a foal?!"

The maid slowly nodded as the princess squealed! She immediately went about the castle, finding all the foals and gathering them in the middle of the room as she rubbed a hoof down her face. “Ok, I should get all these foals to their families until the spell is over… and then I need to find Celestia, Luna and Fancy Pants.”

At the transformed garden party, Fancy pants heard what was going on through the foal monitor and squeaked. “Oh no we gots to go!” He blushed and did a cute dance, but Fleur came over.

“Stop it, Fancy Pamps! Ya not going anywhere without me!”

Fancy rolled his eyes, reluctantly accepting the terms, then he went over to Celestia and Luna. “We gots to go! Twiwy is gone fow a few minutes but when she gets back we gotta be in ta castwe if we dun wanna get in twoubwe!"

The princess reluctantly nodded as they went to the playpen and asked the diapered clown butler if he could open the gate for them. He did so, but all the foals squealed before running off into the castle. Since they were already foals they no longer feared setting hoof inside it!

Celestia and Luna squealed as they ran after the foals all stumbling about in the castle as some noble babies babbled. “Wets have a diapee gawa!”

"Yay! A diapee gawa!" The foals cheered, as they began dancing and causing a ruckus while running around and screaming.

At that moment, Twilight came stomping down from above, having heard all the commotion. “Ugh, seriously?! All of you were afflicted! Now I have to find families for all the nobles too!”

Discord suddenly appeared with a smirk. "You know what? I have a better idea,” He turned them all back into adults, but they were still wearing diapers. “How about you all have your party in the garden but in diapers? You can’t take them off. Then you may go, but only after midnight. Leave before then and you’ll be turned into a foal.”

The nobles blushed and waddled off as did the maids, butlers and guards. That left Fancy Pants, Celestia, Luna and Fleur, who was still a toddler. Discord turned to Fleur and chuckled, ”So you want to stay a toddler?”

Fleur blushed and scrunched the pull-up between his legs. “Is tat otay with ya, Twiwy? Ya gonna have to cawe fow me too. But I wanna be with my husband!”

Twilight rolled her eyes, not wanting to care for another foal, but at the same time she didn't want to disappoint the filly and sighed. “Fine. I suppose one more foal won’t be too much of a hassle. At least this one is old enough for potty training and can be left alone.”

Fleur squealed and hugged the alicorn princess as Discord shrugged. “Well, fine. I'll take pictures of the dinner party. This is going to be fun."

Fleur took Fancy Pants in her hooves and hugged him as she exclaimed! "Tis is gonna be fun! Now I gets to be a big sissy to ya, Fancy Pamps!"

Twilight slammed a hoof to her face and sighed as Discord disappeared. ”This is getting more and more difficult. At this rate I’m going to be the princess of motherhood when this is all said and done," She groaned. “I think I’m going to need back up on this one.”

Chapter seven: How NOT to be a Princess

Another week flew by as, Fancy Pants groaned while slowly waking up in his crib one morning only to see his wife Fleur standing over him. For some reason she had her hooves on her hips, which was not a good sign. The colt groaned and let out a loud yawn, “Ugh, was going on here? Why ya waking me up again?”

The older filly simply rolled her eyes and snapped. “What do you think? You want to leawn how ta use the potty, don’t ya? Ya wants to be cawwed Fancy Pamps fow anohtew week?”

“Of couwse no! But I a bedwetter, I pwobawby awweady peed my diapee.” The colt snapped back.

Fleur tapped his padding making it crinkle as she explained. “That's why I woke ya up supew ewiew befowe ya peed,” She then yanked him by the hoof. “Come on, we need to get going! The potty’s not gonna wait for ya!”

“Huh, wha?!” The little colt squeaked as he was suddenly yanked from his crib and led through the halls of the castle by his wife. He squeaked more upon realizing that his wife was leading him to the bathroom. “Wait! What ya thinking, Fweuw?! Ya taking me to ta big potty!”

“Yes, there’s no other potties awound. Now come on, do ya want to be called Fancy Pamps forever?” Fleur snapped as they entered into the nearby bathroom.

The little colt groaned, looking at the giant porcelain bowl as he grumbled. “Weww no...bu...” He slowly got up and poked his diaper, making squishing sounds with each poke as he grumbled. “I alweady pee. Sewiouswy, Fweuw, ya know I can’t weawwy contwow mysewf anymowe.”

“Oh deaw! I can’t believe that happened again! Ya such a siwwy foaw!” Fleur exclaimed as she took out a bunch of diaper changing supplies and exclaimed. “I think is time to clean you up! Ten maybe you can sit on the potty like I do.”

Fleur then placed the colt down on his back and began to untape his padding before cleaning his rump up with foal wipes.

As his wife continued to clean him and powder his rump, Fancy Pants crossed his hooves and snapped, “I know what ya doing. Ya know tat its Nana Twiwy who does tis stuff and ya just twying to act wike ya in chawge, awen’t ya?”

“Wha, of course not! Ya just being siwwy! Now stay stiww, I need ta tape ya in a new diapee.” Fleur responded with a blush growing on her face. She continued with the change and was as good as her word about the diapering.

Once done, Fleur grunted as she lifted her husband and with a great deal of effort got him onto the toilet seat.
Twilight came in just as Fleur was pulling down Fancy Pants’ diaper. She was a bit chubbier now with her face bloated out. She was munching on a piece of cake as she asked. “What’s going on here? I heard some strange things on the baby monitor. And now I find you two in the bathroom by the potty.”

The foals both turned to Twilight as Fleur proudly raised her hooves. “I went potty by myself! And I twied to get my hubby to go on ta potty but he just made anothew pee pee accident. I wanted him to sit on it for a while wike I do.”

Twilight lifted the filly in her magic and nuzzled her with her muzzle as she cooed. “Oh how wonderful. And you were helping Fancy Pamps too, that’s so adorable!”

Fleurr kicked about in her cute pink pull-up, giggling and gurgling. "Aww, tanks Nana Twily!"

Fancy Pants got a little angry, crossing his forelegs. “I not Fancy Pamps! And Fweuw just wanted an excuse to change my diapee. I dun even have to go,” Fancy Pants rolled his eyes. “Get me down fwom hewe.” He was too afraid to try and get off by himself. Fortunately for him he was soon carried off by Twilight’s magic.

Twilight then took the foals within her aura of magic and cooed. “It's so early in the morning, I think you two should get some more sleep before the twins get up. We can work on potty training you later, Fancy Pamps. I promise, there aren’t gonna be anymore potty monsters.” She took the two to her bed and laid down as she once again slowly drifted the foals over to nurse.

Fancy Pants was soon attached to a teat to the underbelly and suckled, gently drinking up the sweet warm milk.

Fleur, however, was unsure as this was the first time she ever was allowed to nurse and whimpered, “Can.. can I drink fwom ya, Nana Twily?”

“Of course, go on. You’re still young enough,” Twilight gently encouraged. The filly shrugged and waddled over and began to suckle from the teat as well, enjoying the warm taste. Twilight, meanwhile, just watched the foals as she gently placed a wing over her charges and cooed. “Sleep well, my darlings.”

A few hours later, all the foals were awake and so was Twilight. So Twilight placed both Fancy Pants and Fleur in a playpen alongside Celestia and Luna, who were both going about coloring with crayons. Twilight turned to Fleur. “Now, I have some important big pony things to do today. Since things will be going back to normal next week I have some last minute things I need to do before Celestia and Luna return to power. Fleur, since your the oldest, I need you to watch the other foals and make sure they don't get into trouble."

“Oh yeah! You can count on me!” Fleur chirped out as she gave Twilight her cute, puppy dog eyes look.

Twilight dawwed and gave Fleur’s head a few pats and cooed. “Good. Alright then. Just fyi, the bathroom is off limits. There are some training potties if you little ones need them.”

“Ok! Bye Nana Twily!” Fleur waved a hoof as Twilight strolled off while continuing to munch on her cake. But once Twilight was gone Fleur turned to face the rest of the foals with a smirk on her face as she shouted. “You heard Nana Twily, I in charge! And now ya gots to do what I say!”

“Bu tat’s not fair!" Both Celestia and Luna snapped back. “We pwincesses, we supposed to be in chawge!”

“Nope, Nana Twily said I'm in charge and ya gots to listen to me!” Fleur shouted back! “Tell them I wight, hubby! Oldest foals are in chawge even if they aren't princesses!"

"Nuh uh ya onwy a wittwe owdew ten us!” Luna remarked. “Ya even weaw diapees at night!"

"I pee ta bed onwy a wittwe,” Fleur retorted. “Ya soak ya pampews aww ta time and poop in tem too!"

"Do not! And ya sometimes have accidents too ya poopy head!" Celestia scolded.

"I don’t and ya two awe feathew bwains!" Fleur growled back. “Only I get to use the big potty, the rest of you are too scared!”

Fancy Pants gulped nervously and scrunched the padding between his legs. He felt unsure of what to do watching the fillies arguing even as he felt he should be intervening to break it up.

Fleur shouted. "I need some backup! Fancy Pamps, come on, ya know I’m right, right?"

Celestia and Luna both turned to face Fancy Pants and shouted together. "Ya know we pwincesses, we suppose to be in chawge! Dun wisten to this poopy head!"

All of this shouting made the poor colt quite nervous. He began to whimper as a loud hissing noise emanated from his diaper. "Uh...I..uh I dun know? Ya making me pee."

Luna bounced on her own thick padding and babbled. "Weww, wets put it to a vote. If ya tink my sissy and I showd be in chawge waise a hoof!"

Only Luna and Celestia raised their hooves while Fleur crossed her hooves and pouted. "Alright who tinks I should be in charge?" She raised a hoof and glared at her husband who squealed out as he raised a hoof. Fleur smirked and crossed her hooves as she snapped. "Looks like a tie, but since Twily told me I was in chawge it's thwee to one so I win!"

Celestia plopped down in her diaper, making a giant cloud of foal powder poof out as she snapped back. "Oh yeah? We need ta make more ponies vote! Tat’s how it wowks!"

Luna raised her hooves and exclaimed. “Yeah! We gonna make aww of Cantewot vote on who shouwd be in chawge among us!”

Fancy Pants blushed and scrunched his own padding as he tried to explain. "Giwls, Fweuw isn't taking over the kingdom she just in charge of watching us whilew Nanny Twiwy is doing big pony stuff."

Fleur crossed her hooves and shook her head as she complained. "Nuh uh! I in charge of helping Twilight run ta kingdom. Like a helper or somethin. Whateva Spike is called."

Celestia rolled her eyes and grumbled. "Oh yeah? Ya tink ya can wun ta kingdom bettew ten us?!"

Fleur snapped back. "Yeah, I can! I gonna pwove it to ya!"

She took out some pieces of paper from her pull-up and placed them down. "I wrote down some new ideas for Twily to twy befowe evewything gets tuwned back to nowmaw. How about ya make some ideas and whateva she likes more make ya ta better helper!"

"Deaw!" The princesses snapped back.

They all began writing stuff down in crayon while Fancy Pants stood there, unsure of what to do. "I just gonna play with blocks and hope that this keeps the fillies busy," He thought before looking at his clearly soaked diaper. “Right after I change myself so I don’t get a rash. Good thing the big potty’s locked up so Fleur can’t make me sit on it. Don’t wanna get eaten!” And he slowly scampered away, leaving the regressed fillies to their antics.

This continued for some time as all three wrote silly ideas on pieces of construction paper with crayons. Fancy Pants scrunched his padding, feeling quite unsure of what to do even while seeing that this fight over was “in charge” was going a little too far. But he was also happy that the writing ideas had kept the bickering fillies busy.

They turned to Twilight when she came back, even as they saw her looking quite exhausted and munching on more cake. Before Fancy Pants could say anything to her, however, the two alicorn foals lifted their pieces of paper into the older alicorn's face, making Twilight daww. “Oh, these ideas are just so adorable!" As she continued to read the silly ideas on the piece of construction paper she giggled. "You know what, I think I'll go about and implement them.”

Fancy Pants squeaked out in horror. “Wait, Nana Twily I dun think tat’s a good idea!”

“Oh don't worry, I won’t really implement them on a permanent basis. I’ll just prank some uptight nobles with them.” Twilight snickered as she waved a hoof. " I can't help it, I have this sudden urge to mother all the ponies in Equestria! Must be a side effect of caring for your littles ones."

Fleur blushed and scrunched her pull-up, trying to look as cute as possible as she asked, “Oh...uh...but whose ideas were better, mine or the princesses?”

“Oh these are all really cute ideas.” Twilight snickered, dawwing as she read some of the adorable ideas. Then Sse ruffled their heads before walking off as the three fillies blinked and groaned.

Fancy Pants, however, was quite frustrated and shouted. “Wha did you do?! Ya gonna make Nana Twiwy a waughing stock with what ya wowte! Ya aww twewwibwe hewpews!”

Fleur and the princesses whimpered unsure as they turned to Fancy Pants and pleaded. “Pwease hewp us! We didn't mean too! We just twying to hewp Nana Twiwy!"

The colt groaned, dragging a hoof down his face. “We needs to fowwow Nana Twiwy and twy to convince her not to do those silly things ya wowte down! Otay?” The other fillies nodded in agreement and then they all waddled off together in their crinkly pampers (or pull-up in Fleur’s case).

Twilight snickered, reading the notes that the fillies wrote down as she walked off down the streets of Canterlot with a strange gleam in her eyes. It wasn't long until she came to a square filled with nobles ponies going about their business. Her eyes instantly lit up as she used her magic to start levitating the poor ponies with her magic while she suddenly exclaimed. "All of you would all look so much cuter in fancy diapers, just like Fleur suggested!”

The confused ponies didn't have a chance to run as they were suddenly (and magically) taped into fancy styled diapers lined with frills. They had bits printed on the padding as wetness indicators. Then Twilight lifted the tabs of each diaper and started to pour foal powder into the innards of their padding. She then let the ponies go and watched as they ran off, shaking their crinkling rumps about and making giant clouds of foal powder poof out.

Then Twilight dawwed, turning to a stall filled with milk jars as she cooed. "Oh, Celestia and Luna suggested I should sell my milk. Great idea!" She then took out a bunch of foal bottles filled with her milk and stocked them on the shelves. The mare running the stall blushed and whimpered. "Uh, Princess Twilight, this is really unnecessary. I don’t think grown ponies would want to buy breast milk.”

“Nonsense, you can’t say you hate it without at least trying it,” Twilight declared. And the shop mare squeaked as a bottle of Twilight's milk was plopped into her mouth and she began to suckle subconsciously. The shop owner moaned and continued to suckle on the bottle methodically as Twilight cooed. "See? Told you.” She walked off, humming to herself as the mare continued to suckle on the foal bottle.

Twilight then went about popping pacifiers into ponies mouths or poofing a diaper or two onto the rumps of random passerby ponies. Twilight laughed, having so much fun with these, cute fun ideas. She looked at the hard ground and smirked as she lit her horn and turned it into a pink, foam material. “There, that’s better. Don’t want any poor ponies to hurst their rumps and get boo boos.”

Meanwhile, Fancy Pants, Fleur, Celestia and Luna all followed a trail of pampered nobles trying tug off their enchanted diapers. Or doing other foal things like suckling on pacifiers or drinking down bottles of Twilight’s milk. Some ponies were in baby bouncers and they even saw a carriage thad had now been turned into a giant foal buggy!

“We have to stop her, she’s gone compwetwy cwazy!” Fancy Pants shouted. “She gonna tuwn aww of Equeswia into a kingdom of foals!”

Celestia and Luna both nodded as Fleur scoffed. “Yeah, tis is aww Tia’s and Wuwu’s fawt! Tey ta one who came up with these dumb ideas.”

“Nah uh! Ya ta one who said it wow be funny if nobwes wowe fancy diapees, not me!” Celestia shouted back.

Luna shoved a hoof at Fleur and snapped. “Yeah. We just said tat it wowd be funny if Nana Twiwy sold hew miwkies ow made cawwaiges foal buggies! Is not aww owa fawt.”

Fancy Pants cried out in frustration and stomped about and shouted. “Sewiouswy?! Tis is not ta time to be fighting! We needs to find Nana Twiwy and stop hew befowe things get too out of hoof! If I have ta I’ww do it awone, and ya can aww go in time out in big, poofy diapees!”

The other fillies grumbled irritably but still followed Fancy Pants. Even if he lacked any authority to punish them, they feared what he might do when Twilight was back to normal. So they stomped about, apologizing to various ponies for the ideas they’d given Twilight.

Eventually, the foals caught up with Twilight and Fancy Pants began shouting. “Nana Twiwy, stop! Ya going cwazy with mommy fevew!”

Twilight snickered and waved a hoof. "Oh, it’s alright Fancy Pamps! I’m making Canterlot a place where anypony can wear fancy diapers and they won't be laughed at," She then used her magic to lift Fancy Pants in the air, who kicked about in his padding, thus making it crinkle and poof out foal powder adorably. "I think you need more diapers around your rump! Fleur had an idea that fancy foals as yourselves should wear more diapers so you have fewer diaper changes.” She started to tape up three more diapers around his rump, making a giant cushion of diapers that were strapped around his bottom.

Fancy Pants kicked and whined. "Ugh! Cewestia! Wuna! Hewp me out hewe!" But he turned to see the fillies (including his wife) were too involved playing with the foalfied nobles! They went about strapping more diapers around their rumps or dressing them in embarrassing outfits like pink frilly dresses (even on the stallions).

Fancy Pants tore at small wisps of Twilight’s mane and cried out. "Am I ta onwy sane one here?! Ya thwee wewe gonna hewp me knock some sense into Twilight! Not make tings wowse!"

Celestia and Luna turned over to see Fancy Pamps wiggling about in his quadruple stacked diapers. They burst into laughter upon seeing his face growing quite red while he tried to place his hooves over his layers of diapers. But of course, there was no way to hide all that padding.

All that laughter somehow snapped Twilight out of her trance. She looked around the place with the ponies all strapped in diapers or suckling foal bottles filled with her milk and she squeaked. “Oh dear. What happened?! Why is Canterlot a huge nursery?"

Realization suddenly struck the mare as she slammed a hoof to her face and snapped. "Ugh! Discord must’ve done this to me! How could I let my guard down?! This is gonna take forever to clean up!"

Fancy Pants raised his hooves and squeaked. “Hey, is otay, it was cute what ya did. I know you can make evewyting nowmaw. But uh, can ya take aww tese diapees off me fiwst?"

Twilight dawwed as she nuzzled him. "Maybe later, Fancy Pamps. But for now, I’d better untape all these diapers from those nobles."

The noble stallions and mares got up slowly, blushing in their diapers and embarrassing foal clothes as they all ran off in a giant cloud of foal powder.

Fleur, Celestia, and Luna all babbled as they raised their hooves wanting to be picked up too. Twilight then hoisted them on her back and cooed. "Now Fleur, since you were in charge, you’re going to have to explain why you foals are out here unsupervised. Even if you were trying to stop me it’s dangerous for little ones to go off on their own."

After they returned to the castle, Fleur told Twilight everything that happened.

The fillies were pouting and crossing their hooves as Twilight remarked. "Well, due to you fillies caring more about being in charge and Fancy Pamps acting the most responsible, he will be in charge when I’m busy.”

“My name is Fan-” Fancy Pants began and rolled his eyes as he plopped back down on his pampered rump, a loud burst of crinkles coming from his four diapers strapped around him.

Twilight dawwed and nuzzled the colt as she asked him. “How about that be your name until you’re an adult again? I think it suits you, especially since I’m going to put your wife in diapers until I can trust her.”

Fancy “Pamps” sighed, hearing the snickering from the fillies and grumbled. “Fine, but ya owe me some miwkies.”

“Of course, you all must be quite hungry after running around Canterlot.” Twilight laughed as she laid down on her side then the alicorn lit up her horn and drifted them to her underbelly and let all four foals all nurse on her crotchboobs.

Twilight gave a deep sigh, feeling quite relaxed and watching the foals all suckling on her crotchboobs. There was something soothing about the sound of the foals suckling on her breasts, mixed with the sound of crinkling diapers and the smell of foal powder. She whispered to herself. “Next week everything should go back to normal. Despite all the craziness, I think I'm going to miss being a mom. I haven’t felt this way since Spike was in diapers.”

Meanwhile, Fleur whispered to Fancy Pants. “I sorry for being bossy earlier. But I do wanna help ya use the potty.”

Fancy Pants whispered back. “Maybe watew, pwobawby befowe bed. Gotta give Nana Twiwy’s miwkies time to go thwough me.”

Chapter Eight: How NOT to Lose Control

A group of noble stallions and mares all met each other at the front of the castle in the middle of the night. The ponies were all blushing as they stood and waited patiently, looking around while unsure of what to do or who they were meeting with. That was, until Discord appeared before them in a puff of smoke with a smirk on his face. "So it seems you all got my invitation, excellent! Are you going to accept my offer and become foals again?"

One mare gulped as she nervously responded. "Oh yes… we would love too."

"But we would like to have some dignity. We don't want to be turned into actual diapered foals, just school foals, ok?" One of the stallions responded as he went about fixing his bowtie.

Discord crossed his claws as he rolled his eyes and scoffed. "Heck no! Sorry, but I specifically said in the letter that you're going to be diapered foals. No ifs, ands or buts."

Another cautious stallion asked in a suspicious tone. "Did you get Twilight's approval for this ?"

"Of course not!" Discord laughed as he snapped a claw.

The nobles all slowly regressed in age, ending up as one year old foals. The fancy tuxedos the stallions wore slowly turned into onesies with button flaps, as thick diapers bloated between their legs as well making the colts all blush. Some squeaked as the button flaps snapped open with a loud pop!

The mares had their fancy gowns turned into a bright pink color as they became frilly and poofy, with extra petticoats, and thick diapers between their legs. They squeaked and blushed as they struggled to walk around in their foalish outfits.

The lord of chaos quickly scooped the foals into his claws and disappeared into Twilight's room. The princess was in a deep sleep, so the draconequus gently placed the foals near the mare and let them nuzzle into her as he placed the covers over them. Then the lord of chaos smiled down at them and snickered. "Have a nice final day, Twilight. You’re going to be in for quite a surprise." The mischievous draconequus then snapped a claw and disappeared in a cloud of smoke.

Twilight yawned as she slowly got up the next morning, wiped her eyes and squeaked at the familiar feeling of somepony suckling milk from her teats. She looked around, seeing many nobles in their foalish outfits, sleeping around her, snuggling into her mane or deep into her underbelly. Twilight grumbled under her breath as the regressed nobles were quite adorable, being chubby from foal fat while wearing their adorable clothes. She sniffed the air and gagged. "Oh dear, you all need changes. My milk went right through you." Her magic lit up as she began changing diapers. The mare then noticed a letter on the bed, she picked it up and read it out loud: "Dear Twilight,

A group of nobles love being babied by you last week and wanted to experience that again on your last day as princess, so I obliged their wishes. Have fun!

Discord"

Twilight rolled her eyes and scoffed. "Ugh, Discord! You just had to pile more work onto my plate on my last day, didn't you?" The mare then turned her attention to the regressed nobles as she finished powdering and strapped them in fresh diapers. "Well, looks like I don't have a choice. I'm going to have to care for all of you." She then laid back down on her side and adjusted the foals around her, making sure they were all nestled in her underbelly and let them continue to take turns suckling gently on her teats.

Celestia rose the sun that morning for the last time as a foal, grunting as it did take a lot out of her in her foalish state. She blushed as she poked her padding, making it squish as she realized this would be her last day as a foal. She turned to see Luna fast asleep under the blankets and suckling on a purple pacifier. Celestia smiled, seeing how relaxed her sister look. She knew deep down that they were going to miss being foals. She then turned to see Fleur coming back into the nursery with a smile on her face.

"Mowning, Cewestia, ya ready to be a big pony again?" Fleur asked.

Celstia blushed while she scrunched her padding and responded. "I guess. I gonna miss it, though."

Fleur chirped out with a smile. "Me too. Being cawed fow by Twiwight was a wot of fun...I awmost wana stay like tis, but my husband and I gots big pony tings we need to do. Though teaching him about ta potty is gweat pwactice fow when we do it with our own foaws."

Celestia agreed, bouncing up and down on her padding as she responded. "Yeah, Twiwy was wunning tings pwetty weww, but Wuwu and I stiww gots to be pwincesses. Twiwy can’t be a pwincess just yet."

"Ugh, Fweuw, ya changed my diapee again?!" Fancy Pants groaned as he woke up, poking his freshly changed diaper.

"Of course I did I not gonna leave ya in ya soggy padding, ya gonna get a wash," Fleur scoffed. “Not my fauwt ya dun know how to change yasewf when ya dun make it to the potty, Fancy Pamps.”

Fancy Pants grumbled as he got up and shook his freshly changed diaper about. "Ya know, when we become big ponies again, ya better not caww me Fancy Pamps anymowe."

"Of course not! Anything tat happened as foaws is a secwet," Fleur responded with a pout. “Though I might have to shawe some stuff if we have foaws of ouw own.”

Luna slowly got up and prodding her own soggy padding, making it squish between her legs. "Yeah, I agwee with tat. We aww gots to nevew eva say anything we did as foaws to othew ponies. Deaw?"

"Deaw!" Every foal shouted in agreement. Then their tummies all rumbled at the same time as Celestia giggled. “Wooks wike Twily is sweeping in, wets go get some hew milkies one more time!"

"Yeah!" The other foals all agreed as Celestia and Luna flew out from their cribs and followed Fleur and Fancy Pants to Twilight's room. They were quite surprised to see the other foals all nestled into Twilight's underbelly as she turned towards them.

The mare lit her horn and drifted the foals gently into her hooves as she hugged them together. "Aww, you all came to visit me on your last day as foals?” They nodded and nuzzled back. She then checked their paddings and started to change their diapers instinctively (except for Fancy Pants). Afterward, she cooed. “Since there's so many of you, I made bottles for each of you with my milk," She then popped said bottles into their mouths as the foals chugged away. Twilight continued. "Even though it's the last day, your nanny Discord decided to make things a bit harder and turned some nobles into foals. But there's something I need to do before I turn the reigns of the kingdom back to Celestia and Luna, so I have assigned Fancy Pamps to be in charge when I have other things going on."

Fleur pouted as she crossed her hooves and grumbled. "I shouwd be in chawge."

Fancy Pants hugged his wife and exclaimed. "Ya can be in chawge when we back to big ponies! Ya caused pwobwems ta wast time ya was in chawge," The princesses both grumbled under their breaths, also still angry about Fancy Pants being in charge of them. The rest of the nobles were then changed as Fancy Pants snickered. “Now we gots to pway some fun games with ta othew nobwes."

Fleur bounced up and down in excitement as she exclaimed. "Yeah, I can't wait! We going to have so much fun!"

Twilight then took the foals in her magic and teleported herself and all the foals, placing them in a playpen. Hours of changing diapers, playing and feeding ensued.

During that time, Fancy Pants made one more effort to try and use the potty before he returned to normal. His limited success so far had been with the princess training potties, and he wanted to try and conquer the great porcelain throne.

Fleur accompanied him, as she always did. Twilight was too busy with the other foals to take any notice.

The young couple reached the bathroom, and Fleur helped Fancy Pants clumsily remove his diaper before she sat him on the toilet with her magic. “Ya know, ya do wook weawwy cute in diapees, tough ya suwe ya dun wana be cawwed Fancy Pamps.”

“Onwy if I get wegwessed again ow someting,” Fancy Pants grumbled as he sat on the seat, waiting impatiently. “Is embawassing!”

Fleur just giggled, especially since she had more patience than Fancy Pants did. Time seemed to pass slowly, yet it seemed nothing would come out. Eventually, Fancy Pants gave up and prepared to climb down.

Fleur, being the naughty little filly she was, decided to mess with her husband by using her magic to flush the toilet unexpectedly! The loud roar of the flush cycle made her husband jump! Luckily, he managed to avoid slipping off the seat. And perhaps unintentionally, he peed a bit and watched it be flushed away.

Fancy Pants snorted as he climbed down afterwards and was wiped clean. “Ya didn’t have ta do tat! I couwd’ve gone down da howe!”

Fleur only stuck out her tongue. “Nu-uh, I’d have saved ya. Besides, it made ya go. Now wets wash ouw hooves and get back to Nana Twiwy. Weast now ya won’t have to get anothew diapee change.”

Twilight was loving her time with the foals on her final day. She made sure to take her time with each diaper change just to prolong the experience. But she eventually looked outside to see the sun setting, and looked at it longingly. It was quite late in the evening as she cooed. "Now, I want you to be on your best behavior I have some last-minute things I need to do before I turn things back over to the royal twins."

Fancy Pants lifted his hooves and declared quite bodly. "Tat means ya aww gots to wisten to me and do what I say! Aftew aww, I potty twained and none of yas awe."

Twilight smirked as she poked his padded rump. "Just don't go overboard, ok, Fancy Pamps? I’ve had just about enough chaos in this month to last a lifetime."

"Ok, Nana, I pwomise to be good." The colt responded, before blushing as Twilight put two diapers on him with extra foal powder as a protective measure. “You just look so adorable with that extra padding, you know that?”

He blushed, seeing that his waddle was more exaggerated. It spread his chubby legs out. “Yeah, you and my wife wowd powbabwy keep me in diapees fowevew if I wet ya,” The mare snickered as she briefly considered the idea of asking Discord to keep Fancy Pants as a foal. She then walked off as Fancy Pants turned to the other foals. "Now what ya wana do whiwe Twiwy’s gone?"

Celestia bounced up and down, getting quite excited as she shouted, Wwe needs a pwushie and piwwow fight! With aww tese foaws, is gonna be wots of fun!"

Luna nodded and responded in agreement. "Yeah! We do really need a bunch of pillows and plushies tough, and I dun see any.”

Then suddenly, from out of nowhere, a bunch of plushies, pillows, and strange foam toy guns appeared on top of the foals! The foals squeaked out in surprise as they just stared at the peculiar objects, but one noticeable thing was that half of them had Celestia's cutie mark on them while the other half had Luna's.

Luna picked up one and shot it at a noblem whose diaper suddenly had her cutie mark on it. She snickered as Celestia shot her gun at Fleur, making her wear a diaper with her cutie mark on it.

"It's time we settwe who ta best foaw is, Tia ow me! I've got ta Wuna nightie night pampews!" Luna exclaimed, grabbing a foam toy gun with her magic.

"Well, I gonna wead ta Daytime Diapees! Ya can't stop us!" Celestia snapped back.

Thus the foals were split into teams while Fancy Pants simply stood back and babbled. "I wun join any team. But I gonna say tat I wiww be ta wefewee: Now ta ruwes are ya stay hewe in this room, ya dun go upstairs or in ta kitchen, ya dun thwow anyting but pwushies and pwwlows ow use ta diapee guns. Deaw?"

"Deaw!" All the other foals exclaimed. They then split off across the throne room, commencing their plush and diaper fight. Celestia and Luna began constructed their forts of pillows while Fancy Pants sat down and sighed. "Weww, I hope tat aww tese foaws just keep temseweves busy whiwe Nana Twiwy is gone."

It was a long, drawn out battle, with plushie stuffing covering everything. Many of the foals were laughing and mostly batting each other with the plushies, or picking their noses. Some even went off playing or coloring, seeming to forget the whole battle. But Luna and Celestia were continuing to fight each other with plushies, slamming them over their heads as the princess of the sun shouted. "Yield! Ya can't beat me!"

"Oh yeah!? Ya can't stop me fwom takin' ovew and make ya aww take a nap!" Luna exclaimed.

They continued to whack each other with pillows, and then they smacked each other pretty hard in the face making the two alicorn foals to start to wail! It created a wave, and all the foals were knocked off away as Fancy Pants squealed in horror (he had looked away briefly when something had caught his attention, though now he couldn’t remember what it was)! He waddled over and exclaimed! "Hey, wha happened?!"

Celestia and Luna pointed a hoof at each other and whined. "She hit me too hawd with a piwwow."

Fancy Pants rolled his eyes. "Ya two say ya pwincesses, yet ya gettin' taken down by onwy a piwwow." The princesses glared at him as they took out their diaper guns and kept shooting at him, making him squeal as he was padded up with five or six diapers, each with suns and moons printed on the padding. All the extra diapers made him fall over onto his thick, padded rump, he and squeaked out as he felt himself pee in his first layer of padding.

Fleur, Celestia, and Luna all smirked as they went about taping him up in more diapers. And Fancy Pants shouted while kicking about in protest. "Hey, stop tat! What ya tink ya doing?!"

"We gonna make suweya aww diapeed up!" The fillies all exclaimed together.

Celestia nodded and exclaimed. "We gonna pwove ta Twilw ya too wittwe to be in chawge!"

"Yeah, one of us should be! We pwincesses!" Luna shouted in defiance.

Fancy Pants squeaked, realizing how terrible everything looked. "Ya thwee pwanned to mess with me and be in chawge?! Ya gonna be adwuts by tomowwow anyways, why ya doing tis!?"

Celestia crossed her hooves and plopped onto her padded rump as she scoffed. "Doesn't matttew, not gonna have Twiwy tink ya was ta best foaw!"

"Yeah! We pwincesses, and we gots to be ta best foaws! We was foaws fiwst!" Luna shouted back with a glare.

The colt rolled his eyes and grumbled. "Whatevew."

But just then, Twilight came down and gasped upon seeing all the plush fabric covering the throne room floor. "My goodness, what happened here?! It looks like a war zone!"'

Celestia and Luna flew over and exclaimed. "Tis is aww Fancy Pamps fawut! He twied to take ovew ‘cause he used the potty!"

Twilight turned to Fancy Pants, who was strapped in dozens of diapers and angrily suckling a pacifier. The mare smirked, she knew that only the princesses could have clearly caused all of this mess. Still, her magic was able to clean things up in a few moments and plop the foals in the playpen. She then took out the pacifier and asked. "Fancy Pamps, what really happened?"

"These two planned all tis to twy to make ya see tat I not good at being in chawge." The foal grumbled as he crossed his hooves.

Twilight shook her head and responded. "Fillies, come on, it's your last day! Don't mean to Fancy Pamps…" She then looked around, noticing a startling absence of little ones! "Where did the rest of the foals go?!” She cried out in concern.

All looked around and saw the door was open! Their mouths dropped in realization! All the noble foals had escaped out into the streets of Canterlot!

"Ok, Fancy Pamps, you stay here. We need to go find those foals before they hurt themselves. I’ll teleport them back here, and I’ll need you to keep them in the playpen." Twilight ordered.

Fancy Pants saluted the alicorn princess with a proud smile on his face. "Ya got it, Nanny Twiwy. I'ww make suwe noting bad happens."

Twilight nodded, then ran out into the streets of Canterlot with Celestia and Luna in a foal buggy (and Fleur on her back), shouting out for the foalfied nobles.

It didn’t take long to find the missing foals. As Twilight and the rest of her normal charges ran around the streets, they heard incoherent babbling and turned a corner to see a bunch of diapered foals waddling about the place, giggling and laughing while shooting their diaper guns at each other. Other nobles were padded up from the crossfire and regressing right in front of Twilight’s eyes! Their clothes turning into foalish outfits and thick diapers expanding around their rumps.

Twilight groaned, but then her motherly instincts kicked in, scooping up the foals, changing used diapers and plopping bottles filled with her milk into their mouths. "Oh, you're all so cute! But I need to stop this before it gets all out of hoof. I can’t take any more of this!"

After teleporting them back to the castle, Twilight continued through the streets she squeaked seeing some of the nobles had somehow constructed a diaper cannon! it shot out big balls made of diaper material, with foal powder filling the air. Twilight dodged the big ball trying to avoid being hit! "Stop it this instant, little ones!" She roared above the commotion!

The foals stopped As Twilight stomped over. But as she looked around Canterlot, she saw foals running around everywhere. "Discord is doing this, trying to make me lose the bet! I can't give up!" She realized.

"Oh, but it's too late. I told you things would get out of your control, and things finally did!" Discord proclaimed, suddenly appearing before her with his claws crossing his chest and a smirk on his face.

"You cheated! You gave them those diapers guns!" Twilight stomped a hoof on the ground, snapped back.

"Well, you seemed to have dealt with every other obstacle I threw at you,” Discord retorted. “I had to make the final day challenging somehow. You mean to tell me that the princess’ prized protege was brought down by a foal war?"

Twilight shouted back in determination. "The day isn't over yet, and I haven't conceded! I will get every noble that was regressed and have them again in the castle. They’ll all be fed, changed, and in bed with a bottle of milk in their mouths by midnight. You can be sure of that.”

"Fine, you have until midnight. If you fail, then every noble regressed today will remain a foal forever." Discord warned, then he snapped a claw as Celestia and Luna got up.

"We'ww hewp find ta foals and teww them to go to ta castwe, ya just wowwie about changing diapees and getting tem to bed." The regressed princesses replied.

Twilight hugged them. "Right, I have faith in you!" She gave the two a bottle of milk each and slipped a pair of foal booties on both of them. "Go find Cadence and have the toddler guards since they were already regressed. We’ll need all the help we can get.”

The princesses both nodded in agreement and exclaimed. "Wight!" They flew off straight to Cadence's house, and they both knocked as fast as they could until the princess of love came over and cooed. "Oh, hello you two! It’s about time you visited me.”

Luna shouted! "We dun gots time to talk! A bunch of nobwes gots tuwned to foaws and we gots to save Cantewot, and we need ta thwee guawds hewp!"

"Yeah, we can hewp!" The three guards all exclaimed in unison.

Cadence was unsure as she gave a deep sigh. "I think this is a big pony situation. Don’t forget, I foalsat Twilight a bunch."

The baby alicorns shook their heads and responded. "If ya come with us, ya might get tuwned to foaws too! Ta guawds awe foaws aweady so tey gonna be otay."

Shining came over and smiled at the foals. "I don’t see why not. Bright Wing’s taught them all what I taught him,” Then in his best captain voice he declared. “Alright, royal guards, you can go help round up the foalfied nobles but be back soon! I want to play with you three today. The best one of the trio gets first dibs on trying the big potty."

They all hugged Shining, who nuzzled them back. They then ran off following Celestia into the streets of Canterlot. Each of them determined to win the prize Shining Armor had set for them. They’d seen him and Cadence visit that big potty many times, and even for Cannon Feather it no longer looked as scary as it had once seemed.

The five foals went about gathering the foalified nobles, telling them the war between Celestia and Luna was over, and that Twilight was going to tuck them in.

All the while, Twilight did everything she’d vowed to do: Change diapers, feed the foals and place them in her bed. It wasn't long until over a hundred foals were now sleeping soundly in the nursery as more cribs appeared with each foal that came in.

Meanwhile Fleur and Fancy Pants did their best to entertain the foals that were too excited to fall asleep in the playpen in the throne room.

But it wasn't long until Celestia and Luna both returned, exhausted and panting from all the flying around they did while finding every foal. Twilight teared up, seeing them being quite worried as she rushed over and hugged them. "Oh, thank you for helping me."

Celestia and Luna looked down as Luna babbled. "Tis wouldn't have happened if we didn't stawt tat stupid fight. Ouw own chiwdwen had to hewp us."

"Yeah, we wiwwy sowie." Celesta cried out.

Twilight just hugged the foals and nuzzled both princesses. "It's ok, every foal is here safe and sound thanks to you...Did you find the toddler guards?"

The baby alicorns blushed as three foals enter the room, blushing while wearing thick diapers all with a mix of Celestia and Luna's cutie marks printed on them. Twilight laughed. "Don't worry Discord should be here to fix things soon."

Bright Wing boasted. “I won! Tat means Daddy gonna wet me twy his potty! I weady to tame that beast!”

Twilight just cooed. “Oh, that’s adorable. But be careful, with my brother you never know when a ‘potty monster’ will make an unexpected appearance. He’d tease me about it often, even though back then I knew from books there was no such thing. With Discord though, all bets are off.”

"Speaking of bets, I’m guessing you won mine," Discord grumbled as he poofed back in. "At least I have a full photo album of what happened. Memories to last a lifetime." Sure enough, he had a photo album depicting all the major foalish events of the month.

Twilight glared at the draconequus. "Well, since I won I think it's about time you turned all the foals back to normal. The ones that weren’t foals at the start of the month."

"Fine, but I think they look better as babies." Discord grumbled.

Luna giggled, as a funny thought entered her mind, and whispered to Celestia. "What if tey stay as foaws?"

Celestia snickered and whispered back. "I dun tink tat wouwd be so bad to be honest. Diapeed nobwes wouwd be supwew funny."

Twilight eyed the draconequus as Discord remarked with a scowl. "Well, much as I’d like the possibility of permanent foalified nobles, a deal's a deal." The lord of chaos then snapped a claw, and the castle reverted to how it was. The nobles instantly turned back into adults, but they were all in diapers still and asleep in the cribs, suckling pacifiers or bottles filled with milk.

The three foal guards were turned back into three-year-old toddlers, but they were now each wearing a thick diaper that read "Back to Square One" printed on the padding.

Fleur and Fancy Pants were turned back to normal, but Fancy Pants’ cutie mark was now a thick, fancy diaper with "Fancy Pamps" written on the padding.

Celestia and Luna were now adults again, but they were wearing pull-ups with "I'm a big princess now!" written on the seats of their padding.

Twilight was back to her normal unicorn form but she squeaked seeing her teats were still big. "Seriously, Discord?! I said ‘everything back to normal’!"

Discord crossed his claws. "Well, I think you cheated having those three toddlers helping you, so they get their potty training reset a little, though little Bright Wing can still claim his daddy’s reward if he’s feeling brave enough. Speaking of the potty, Celestia and Luna now can teach them about, being good examples, and whatnot. And as for you, those boobs will help you sustain two other foals."

“Wait, what do you mean two other foals? Don’t tell me you’re going to regress more ponies!” Twilight growled in protest.

“Oh you’ll find out soon enough.” Discord vaguely replied, and Twilight blushed, seeing the two mares she’d cared for a month standing over her. The two of them blushing and turning their heads unsure of what to say.

Discord sighed, "Well, that's it for now. I should head to Ponyville to fix up your friends and the Cake Twins."

Celestia and Luna both couldn't help it anymore and rushed over to Twilight, and they both embraced her in a giant hug and exclaimed. "Thanks, Nana! You were great!"

The princesses then squealed at what they said, making Twilight laugh. "That was adorable. And yeah, it was no issue I would care for you two again in a heartbeat, if I had to." She then came over to Discord, and he snapped a claw as they went to Ponyville.

Celestia and Luna teared up, missing their nanny already. But Celestia then squeaked out, feeling the familiar pang to use the bathroom. "Luna, I have to pee!"

"Me too!" Luna shouted as they flew off as the three toddlers blushed, feeling their padding squish, knowing they’d already peed their diapers.

Cannon Feather whimpered as he poked his squishy yellow-stained diaper. "Wooks wike we wost owa potty twaining."

“Wew, tatas otay, we can weawn fwom Mommy Tia and Auntie Wuwu on what to do. Wets go fowwow tem!” Bucket Bridle exclaimed!

“Gweat idea!” Bright Wing shouted. “We gots to huwwy though, tey way ahead of us!”

They all rushed off after the princesses, hoping to see how they use the big potty.

All Fancy Pants could do was just stand there, blushing while looking at his new cutie mark. “What does this even mean? I hope I don’t actually need diapers.” He blushed.

“We can find out together, Fancy Pamps!” Fleur teasingly replied as she took him by the hoof. “Come, why don’t we take you to the potty as well?” And she led her husband away before he could utter a syllable of protest.
