Chapters Twilight Sparkle blinked as she was starting to wake up and yawned, stretching her hooves over her head, feeling rather tired. She just had her coronation yesterday, which was rather exhausting. Princess?! She couldn't believe she was indeed a princess of Equestria now! It was still a lot to take in all at once, and the alicorn still couldn't believe it all was real, considering the bizarre events that led up to her coronation.
But then Twilight felt something was off, as she could feel something soft and crinkly hugging her waist, and that was when she noticed that she was surrounded by white bars and her bed was much smaller than what she was used to. Twilight then looked down at her pudgy hooves, maneuvered the covers around her, and saw she had a cute little pot belly with pudgy hindlegs. She gasped, slamming her hooves into her chubby cheeks as her tiny wings unfurled and cried. "I a baby again?!"
"That's right, little Twily." A soft, motherly voice cooed. Twilight then looked upward at Princess Celestia, slowly trotting over towards her. The alicorn princess lit her horn light and levitated Twilight out from the crib.
The filly started squeaking, seeing that her diaper was stained yellow and sagged beneath her nether regions. The alicorn with a light purple coat felt so embarrassed as she threw her hooves over her eyes.
But the elder alicorn princess was undeterred as she just laid Twilight down on a changing table near the crib and went about the diaper change as if this was routine.
Twilight gave an exasperated sigh as she laid her head back and mumbled. "This is like, what, the third time I got turned into a baby?"
"That's correct. Honestly, at this point, I might just leave you in diapers. I think it's the universe telling you you're just not ready for potty training." Celestia joked as she rolled Twilight onto all fours and had her stand up.
The little filly was a bit unbalanced with the extra padding spreading her thighs apart. She started to waddle about as she'd gotten used to being in diapers after being turned into a foal multiple times. "So, what happened this time?"
Princess Celestia then took Twilight, laid the filly down in her lap, and cooed, "Oh, nothing serious, just that your body is still getting used to all that energy from when you became an alicorn princess. Luckily for you, Spike found you like this and informed me immediately of what happened."
"So, ya gonna turn me back to normal soon, right?" Twilight asked while eyeing the princess, knowing that she would love to baby Twilight (which could influence her decision-making.
Princess Celestia gave Twilight a playful smirk and then said. "Oh, you'll return to being a big pony soon enough. Your body will adjust in a few hours, I promise," She then levitated a bottle, held it close to Twilight's mouth, and cooed. "But until then, Mama Celestia will take good care of you. Now come on and drink some breakfast."
Twilight was hesitant, but she eventually latched onto the nipple and began to suckle down the contents, tasting a creamy substance like a melted cake. She had done this before, but she still blushed, knowing full well it was Princess Celestia's own milk she was drinking. Still, she chugged on it anyways as she loved the taste of the warm, creamy liquid down her throat. She didn't waste a second chugging the mare's milk down…because it reminded her of the first time she'd been turned into a baby...
A year ago...
"Oh, thank Celestia Fluttershy didn't get banished, or worse!" Twilight cried as she trotted back into her library and slammed the door behind her as she collapsed on the ground.
It was still very stressful despite Princess Celestia being very forgiving about Fluttershy foalnapping her pet Philomena. She then got up on her hooves and started to head into the kitchen to make herself something to eat. That was when she felt her forehead beginning to heat up. It was a burning sensation she had never felt before. Maybe she'd caught something from all of this stress? Twilight thought a warm cup of tea and a nice bath should do the trick.
The unicorn continued towards the kitchen until she suddenly sneezed, engulfing her entire body in a cloud of smoke. She coughed and sneezed, then tried to say something, but only gibberish came out. The filly tried to move but seemed unable to control her limbs as she flailed them. Twilight had no idea what was happening, feeling scared about the sudden transformation! The filly started to whimper and cry. But then the door opened, and to Twilight's surprise, Princess Celestia trotted inside. "Oh dear, you caught the Phoenix Flu! Don't worry; you're not the only one."
Celestia then levitated a padded yellow coated pegasus filly (who was Fluttershy) with a wispy pink mane and tail. She was placed down with a plush rabbit held close to her hooves. Then Celestia levitated two white-coated pegasi colts, who Twilight recognized as the princess' guards. They were adorable with their wispy blue manes and strapped up in thick diapers (with cute little baby blue shields and sword prints on the padding).
"When normal ponies are around Philomena when she goes through her rebirthing process, they're regressed into foals. I nicknamed this 'The Phoenix Flu,'" Celestia explained as she trotted towards Twilight, levitated a diaper and a container of foal powder, and then continued. "I do apologize for not explaining all of this earlier. Still, I didn't think it was necessary until I noticed Philomena was missing." She then began powdering Twilight's flank (which felt rather lovely to Twilight, especially with the smell of cornstarch wafting through the air) and taped her up in a fluffy, white diaper. It was so soft and comfy to have around the nether regions.
Twilight squeezed the padding between her legs, feeling the cumbersome diaper around her flank.
Princess Celestia then raised her charge up as she explained. "Now, don't worry, I have the cure for Phoenix Flu, but the way for you to take it is rather embarrassing. I'm sorry in advance that there's no other way. But the alternative would be for you to grow up all over again, and something tells me you wouldn't be a fan of having to go through potty training a second time. Just teaching Luna after she got back from the moon was a hassle." She then laid down on her side, revealing two round teats bloated with milk.
Twilight threw her hooves over her face, embarrassed at the princess exposing herself and knowing she'd have to nurse from her teacher. At least if it had been her mother, it wouldn't feel so awkward (even if Celestia was kind of like a mother to Twilight sometimes).
The princess noticed Twilight being somewhat embarrassed and reassured her. "Oh, don't worry, my teats aren't always like this. It would be uncomfortable if they were. The cure is a capsule, and I swallowed it easier just in case anypony got the Phoenix Flu. Then, with some magic, it allows my teats to lactate. So go ahead and nurse; you'll be out of diapers within a few hours. I promise."
Twilight was then gently levitated near one of the sun princesses' teats, and she was hesitant to touch it, let alone place her mouth on it. And who could blame her, even considering what the alternative was?
"Go ahead. Latch on, sweetie." Celestia whispered and cooed, nudging Twilight with her magic until she did as her mentor instructed. Her little mouth latched onto the nipple, and she began to suckle. As Twilight continued to drink her fill, she was surprised at how warm and sweet the milk was as it went down her throat. She nursed on it until it became rhythmic and did so for some time.
It wasn't long until Twilight started blushing, hearing a hissing sound from her padded nether regions. The unicorn began to squirm and whine, feeling embarrassed about having used her diaper. But Celestia started to whisper. "Don't worry, you're a baby and doing what babies do. Relax and drink; this will all seem like a bad dream in a few hours. This isn't the first time I've had to do this; my own royal guards have been regressed accidentally by Philomena more times than I can remember."
Twilight seemed to nod as she continued to suckle the milk in a much more rhythmic fashion, not worrying that she was wetting herself, something she hadn't done since she was in magic kindergarten.
After Twilight had drunk her fill, the princess wiped her little filly's mouth with a foal wipe and had her diaper changed in the blink of an eye. Twilight was then padded up and had her diaper patted as Princess Celestia cooed. "Now go on and play with Fluttershy, I have to nurse my guards now, and I think they'd like some privacy."
Twilight then waddled off towards the yellow-coated pegasus playing tea party with her plush bunny and the colts with teddy bears. Meanwhile, Princess Celestia levitated the two colts towards her teats as they kicked and squirmed (they were much more embarrassed at having to nurse from her).
Twilight and Fluttershy just watched and giggled, seeing the two fighting Princess Celestia. Eventually, the princess snapped. "Stop fussing, you two! You need to drink, or you'll have to grow up the old fashion way. Do you want that? I think not."
Twilight couldn't help but chuckle as she turned towards Fluttershy, who looked rather cute, hugging her plush rabbit to her chest with her diaper crinkling as she whispered. "So…um…guess things could be worse?"
"Yeah, guess we learned our lesson well." Twilight babbled back as she picked up her Smarty Pants doll and began to play with her friend.
The Cute and adorable Trixie Returns!
Hissss
The sound of wetting her diaper made Twilight squeak in surprise, pausing her feeding.
Celestia gently removed Twilight from her teat and wiped her mouth as she cooed. "It's alright. Remember when you first peed your diapers? It's okay; you can't help if you're not big enough for the potty."
Twilight threw her new wings over her eyes, still feeling somewhat embarrassed about wetting herself in front of her mentor (and possibly doing the other thing).
The princess didn't mention it as she levitated the little filly into a playpen, placed her down with her Smarty Pants doll, and said. "Now, I think you should play with another foal to pass the time. I think you'll find this one to be very familiar."
Twilight was a bit confused about who she would be playing with, as it would be awkward for her to play with an actual baby. But then her questions were answered as Princess Celestia levitated a light blue coated baby alicorn, all padded up in a cute diaper with little faint blue stars and moons printed on the seat. As Celestia placed the filly next to Twilight, the baby alicorn gasped in surprise. She sat down next to Twilight as she shoved her hooves over her pampered crotch and cried. "T..T…Twilight!?"
"Trixie!?" The other regressed alicorn squeaked back.
The sun princess alicorn snickered. "Yes. Little Trixie here has been in the same boat as you for a month now," She ruffled Trixie's little man, "We've tried to keep things under wraps. Still, eventually, everypony will know Trixie is a cute baby alicorn now. She's part of the family."
"Stop it, auntie! Ya embewassin' me!" Trixie whined as she kicked about in her crinkling pampers.
Trixie then mumbled a curse under her breath as Twilight threw her hooves across her puffy chest. "Yeah, I remember when you tried to turn me into a baby like yesterday."
A few months ago
It was early in the morning with Trixie standing across from Twilight, glaring at each other. Twilight knew something was off with Trixie as she had been using advanced magic to bully Twilight's friends. She stood her ground, ready to take her own, wondering what kind of spell Trixie could use.
"Now for an age spell!" Trixie proclaimed as she aimed her magic right at Twilight! With a blast of red-colored magic, a cloud came over the two! Twilight coughed and gagged as she looked down at her body as it dispersed. She was pudgy and trim again, like when she had the Phoenix Flu. The unicorn then looked over to see that Trixie was struggling to get out from underneath her hat.
Trixie tossed the hat aside, revealing her small pudgy form with the alicorn amulet now gone. She had two wings protruding from her back. Twilight was somewhat surprised to see that Trixie was now a baby alicorn! Trixie didn't seem to notice that she was from a different tribe, yet she pointed at a hoof and shouted. "Ha, Trixie's spell may have misfired, but now ya a foal as well!"
"So what? Ya in diapees too!" Twilight babbled.
"Well, not really!" Trixie huffed as she tried to stand up. "Even as a foal, Trixie dun need diapees! Trixie was so gweat and powerful that she mastewed potty twaining before she was even a yeaw owd!"
"Nah uh, nopony can do tat!” Twilight retorted. "Now ya gonna pee pee all ova ta place!"
"Ya gonna do tat too!" Trixie snapped back.
Soon the two babies continued to argue, screaming and shouting at each other over who was more of a foal. And it went on and on until somepony shouted. "Girls! That's enough!"
The babies shut up rather quickly when they saw who had spoken: A very demanding Princess Celestia, who quickly levitated the two towards her. She then powdered their rumps and strapped up diapers over their flanks.
"Trixie sta-" Twilight squealed as a pacifier was placed into her mouth.
"-I don't care who started this nonsense!" Celestia snapped! "This has gone far enough! You both have been very naughty, messing about with forbidden magical artifacts! And look where it got you two, back into diapers."
Trixie giggled but squealed as she was levitated to face the princess, who snapped. "Now, Trixie, you have gone way too far trying to turn my pupil into a foal. As punishment, you will be her playmate and be a good foal to her while I search for a way to reverse your little age spell. I will permanently leave you as a foal if you don't behave. And we'll see how 'Great and Powerful' you are when filling you're pampered daily. So play nice."
"Yes, Mama!" Trixie cried, feeling somewhat surprised as the alicorn plopped both squirming babies into a carrier on either side of her. Twilight felt odd to be in the air a few feet off the ground.
"Lucky for you two, I anticipated Twilight might turn into a baby again. So I have a nursery already set up." Princess Celestia explained as she unfurled her wings and flew off towards Canterlot, leaving the ponies who'd been watching baffled and confused as to what just happened.
Little Mac and the Enchanted Dolly
"So that's why Celestia didn't turn ya back to normal?" Twilight asked, being surprised at the fact that Trixie was still a baby alicorn.
The filly nodded and explained. "Ta alicorn amulet fused inside me and turned me into a baby alicorn, making it impossible for an age spell ta work on me. Now I gotta grow up ta old fashion way. So Trixie is stuck in diapees because she has no choice." She yawned and squealed as she felt her diaper was now wet. She got up, revealing her soggy diaper as Twilight giggled. "Yeah, ya just doing what babies do."
"Buck o-," Trixie growled.
"-Language!" Princess Celestia scolded. "If you finish that sentence, you'll get your filthy tongue washed out with soap."
"Sorry, Auntie Tia!" Trixie squeaked, covering her face with her hooves. "Dun tell Mommy, or she'll ground me forever."
"Wait, Princess Celestia didn't adopt you?" Twilight asked as she scratched her shortened mane.
Trixie shook her head. "Nah, Mommy Luna did. She gonna help reform me and make sure I grow up to be a good princess."
"Yes, and I would say my sister is doing a good job of that so far," Celestia nuzzled Trixie as she laid her down for a diaper change. Twilight watched as the princess changed Trixie's diaper and saw how fast and efficient she was in her duties. She'd gotten really good at changing diapers. When Trixie was in fresh padding, Celestia bent down and gave the baby a raspberry, making her giggle and squeal in delight. "Aww, there's my baby Trixie. Such a good little filly."
Twilight pouted and babbled, "I wouldn't say she's a good filly."
Celestia plopped Trixie down next to some foam blocks, turning her attention towards Twilight. "Well, I would say that you also were rather naughty not too long ago. And I think you know what I'm talking about, Little Miss Sparkle."
"Ya talking about when I put 'Ta Want It Need It' spell on my Smarty Pants dolly?" Twilight babbled as she threw her tiny wings over her eyes.
"Oh! Tell us, auntie! Tell us the story!" Trixie babbled as she bounced up and down on her diapered flank.
Celestia giggled as she sat down on the rocking chair and said. "Well, I won't go through all the details. But Twilight was freaking out that she didn't have a friendship lesson ready for me. So my star pupil got the bright idea to put a 'Want it Need It' spell on her Smarty Pants doll, which made the entire town go crazy. Luckily for her, I could put a stop to the madness."
Trixie burst into laughter as she kicked about in her diapers!
"Yeah, tats it! Nothin' else happened, all right?" Twilight replied in a somewhat embarrassed tone.
Princess Celestia brushed her mane over her head. She whispered, "Well, let's just say some magic was still inside the Smarty Pants doll, and somepony was turned into a foal."
A few months ago
Princess Celestia was slowly walking up towards the Apple family's house at Sweet Apple Acres, having just had to scold Twilight for making half of Ponyville go crazy. Now she'd gotten word that Big Macintosh, Applejack's brother, had regressed to a foal. She could hear crying outside the door, confirming that what Applejack said was true. She waited for a few minutes until Applejack opened the door and bowed. "Oh, Princess Celestia, you're here!"
The alicorn sighed, hearing the crying growing louder within the home. "I heard that Twilight's doll turned your brother into a foal?"
"Yes, please do come in!" The farm mare nodded as she led Celestia in, as she turned to see a chubby, red-coated colt in a high chair, currently throwing a nasty temper tantrum.
Applejack quickly trotted through her home as she explained. "Look, I know it's the doll makin' my big brother stay a baby. But he throws a fuss every time I try to take his Smarty Pants doll away! I was just tryin' to feed him to help calm him down, but he's been throwin' a temper tantrum for the past few hours. You've gotta help me."
The princess just nodded as she listened to Applejack and followed her into the kitchen. She turned her attention to the little foal, took a feather out of her wing, and started to tickle his belly, making him kick and gurgle as he blew bubbles from his mouth.
Applejack had to place her hat over her chest as she cried. "Oh, wow, you calmed him down quick! I don't think even my Mama could've done that."
"Oh, he's just a fussy little colt, is all. Trust me, he's not the first. I've had many in my royal guard who've turned into foals," Celestia explained. "Some of them have been even bigger babies than he's been. At least this little one knows he must wear diapers for protection." She then placed the padded little colt on her back as she bounced the chubby colt up and down on her back.
Big Mac giggled and squealed as she did so, and Applejack just watched with a smile being rather touched at the scene.
"Now, I'm going to feed him some of my milk if that's ok with you?" Princess Celestia asked, looking up towards Applejack, who was taken back by request and stammered. "Ye…yeah, sure. I mean, he's a foal now, so he needs his nutrition. Ma ain't around anymore, and I don't think Granny Smith would be too keen on feedin' him like that."
"Ok, I'm just making sure you're ok with it," The alicorn replied as she sat down on their couch and slowly levitated a bottle of milk into his mouth. "There, now all he needs is his num nums."
Princess Celestia and Applejack watched as Big Mac slowly closed his eyes as he suckled down on the rubber nipple, making adorable gurgling noises as he did so.
Big Mac chugged down the contents rather quickly, and when he finished his bottle, the princess removed it and plopped a pacifier into his mouth. She then took the doll away and watched as the small baby grew up back into a bulky stallion, still sleeping soundly with a pacifier bobbing up and down in his mouth. "There, now just let him sleep. I'll take this and remove the curse." Celestia chimed as Applejack sighed, "Thank you, princess. I don't know what we would've done without ya. It's been a while since we had to raise a foal that young."
"I'm just glad your brother is ok," Princess Celestia added as she got up. "Now, I'm going to ensure this doll has no curses. Meanwhile, monitor your brother. If he's still acting foalish, let me know, ok?"
"Yes, mam, will do! I'll be sure to get with ya faster than my brother can chug down a bottle filled with your milk!" Applejack teased. "Although, it might be kind of nice to be the oldest siblin' for a change."
Princess Celestia's cheeks flushed red as she trotted out the door, feeling the weight of her teats beneath her legs. All of these ponies turning into babies recently was messing with her hormones. At the very least, she'd have to continue donating her excess milk to hospitals as she made a mental note to set up another appointment with her doctor. Oh, would she ever explain this to him?
"I accidentally turned Big Mac into a foal?!" Twilight cried, throwing her wings over her face again as she felt somewhat ashamed.
Celestia nodded. "Yes. Applejack kept the situation under wraps, and she had Spike swear not to speak of it since she used him to send me letters. But everything is fine now. Last I heard, Big Mac is doing very well for himself. Using the big pony potty and wearing his big boy pants with pride. Truth be told, I think he kind of likes not always being all grown up all the time. But I'm sure he'll graduate from pull-ups before much longer."
Trixie was just laughing most of the time and babbled. "Works wike ya not perfect, Twilight!"
"I never said I was!" Twilight snapped back as she threw her hooves across her chest and stuck her tongue out.
"Meanie butt!" Trixie growled.
"Poopy head!" Twilight stuck her tongue out again.
"Girls, that's enough! Behave, or you're both going to get spanked!" Celestia sternly scolded.
"Yes, Auntie Tia. Sowwy." Both foals chimed as Celestia turned towards Twilight and asked, "Now, Twilight, wasn't there that one time I found you acting like a foal? You mentioned how your mind swapped with that of your mind from when you were a foal. Is that correct?"
Twilight groaned as she threw her wings over herself. "No! Not gonna tell ya! Not in front of Trixie!"
"Come on, pwease?! I promise I'll stop teasing ya!" Trixie chirped as she started to bounce up and down on her crinkly diaper.
Twilight threw her wings back and then grumbled. "Fine, but it's not like it was anything special," She then recalled. "So, I came here to look for a time spell to stop myself from going crazy thinking something bad was gonna happen. But I used the wrong spell and remember waking up in my old room as a foal…."
About twenty years ago
Twilight groaned, rubbing her head as she looked around her room. She saw she wasn't at the Golden Oak Library where she should be. Instead, she was in some sort of nursery. The room looked oddly familiar, resembling her old room back with her parents! In fact, minus her bookshelf being replaced by a diaper changing table, it was her old room! Twilight started to get worried as she looked down underneath the baby blankets that covered her and gasped upon seeing a diaper hugging her waist!
"No, no, no! I went back too far!" Twilight cried, getting up on her hooves and seeing her plump little body with her pee-stained diaper. She started to get agitated and began calling for help almost out of instinct. Eventually, she heard her mother come in, shhhing her as a tired-looking mare trotted towards her.
Twilight Velvet yawned as she took the chubby little foal and laid her down for a diaper change. "Don't worry, sweetie. Mommy's here now."
As Twilight Velvet went about the diaper change, Twilight started to plead to her, "Mama! Ya gotta listen ta me! I, not ya baby, I from ta future! I gotta go to Canterlot's royal archives and find a time spell to get me back to my adult body!"
"Oh, so talkative. And so imaginative too. I wonder what's gotten you so riled up?" Twilight Velvet asked rather sleepily. "You're usually not this fussy at this time of night."
"Mama, is baby Twilly up?" Twilight gasped upon hearing her brother's voice! She turned her head to see Shining Armor as a school colt trotting over with a sleepy look.
"Yes, she is, but there's no need for you to worry. Just go back to bed, sweetie. After all, tomorrow, you've got your first day at magic kindergarten." Twilight Velvet chimed as she escorted Shining Armor back to his bedroom, asking whether he needed to "go potty" and if he got his Brutus Force doll "for show and tell."
By now, Twilight was clinging to her mother's mane. She bounced up and down on her mother's back with her diaper crinkling and foal powder puffing out from her padding. Many thoughts were going through Twilight's head as she wondered what she should do. Should she try to go to the archives on her own? But seeing her stocky body and diaper, she would be picked up and placed back here by anypony. And Princess Celestia knows if she could even read!
"Mama, can I say goodnight to baby Twilly?" Shining asked as he was now tucked under his covers. Twilight Velvet gently placed her daughter in Shining's hooves as he kissed her goodnight.
Twilight blinked, seeing that she'd blanked out for a moment in her own thoughts, and now she was in her parents' bedroom with her dad snoring in the master bed.
Twilight Velvet then climbed under the sheets and adjusted herself to lie down on her side as she said to her daughter with a sleepy smile, "I know you're just hungry, huh? That must be it. Well, go ahead, get your num nums. Don't drink too fast; you remember what happened last time."
Twilight groaned, knowing what would happen next, as she felt levitated towards her mother's busty teats. It wasn't long until her mouth latched onto one of her mother's nipples, and she began to suck down the milk. Eventually, Twilight was in a dreamlike state. Despite not having any memories as a foal, she could recognize the sweet taste of her mother's milk. The milk calmed her down, and she relaxed as she suckled away, feeling much more content as Twilight Velvet cooed and doted over her daughter, telling her how much she loved her. It was a special touching moment, and it was something Twilight would never forget.
"Wow! You somehow went back to when you were a baby?!" Celestia cried in surprise.
"Yeah, pretty crazy, huh? That was when I woke up and found myself back in my adult body but all diapered up." Twilight explained as she blinked, hearing her voice was much like her much deeper adult tone. She then looked down and saw she was now much taller, towering over baby Trixie, who was babbling and cooing at her, seeming to be angry that she was out of diapers.
Then it hit Twilight! She and Trixie had been talking in baby babble the entire time. How could Celestia know what they were saying? Twilight turned towards Celestia and asked. "Wait, you can understand, baby babble?"
"Of course, you pick up on a lot of things over the years," Celestia snickered as she trotted over and hugged Twilight, wrapping her tightly with her wings as she said, "As much as I love babying you, I'm glad you're all grown up now. Maybe you'll stay that way this time."
Twilight couldn't help but nuzzle her back, loving how much of a connection the two had now that Celestia had nursed her and changed her diapers. It was odd, but the princess seemed to see Twilight was almost like her daughter.
Twilight then looked around the room and asked. "So.. you'll keep this nursery…just in case I accidentally turn into a baby again."
"Of course! Never know if you'll go back to diapers," The princess chimed. "Or there may be other side effects to your transformation that might affect your potty training. Who knows?"
"Hopefully, that won't be any time soon, but thanks all the same!" Twilight cried before flying off, still somewhat embarrassed about the whole situation and wanting to leave as soon as possible.
Meanwhile, Celestia just sat back with a smile, secretly hoping Twilight would somehow turn back into a baby soon and maybe for a much more prolonged period of time. Maybe for long enough to get to experience Twilight's toddler years. Possibly Twilight would be easier to potty train than Luna or Cadence had been?
