Throne of Foals

Celestia was sitting rather calmly down on her throne, having just finished working on a few last-minute papers. It was only when the room fell oddly silent did the princess start to notice something was off. Looking around, she saw that nopony was around. There were no guards, butlers, maids, or pony seeking her audience. It was rather odd. Was it some sort of holiday? Then she heard a feminine robotic voice say out loud. “Hello princess Celestia! I'm happy to see you here! Let's get you ready for the day!"

The princess of the sun blinked as she squeaked as the throne started to morph, turning from its metallic feel to hard plastic. The back of her chair turned into plush material that molded around the princess's back. Princess Celestia sunk into the back of the seat. She started to get somewhat nervous, wondering what could be going on. Then she felt magic tendrils tugging on her mane as it was tied up in ponytails. Then she found a yellow T-shirt that read "Little Sunny Butt" on it over a picture of a smiling sun dressed around her chest. She squeaked as a tray appeared in front of her. She immediately tried to escape by flapping her wings. Still, there was a buckle around her waist, and she also felt relatively weak, as if some magical force was keeping her in the seat. The princess of the sun tried to use her horn to teleport, but it just fizzled, sending some sparks. Clearly, whatever spell was keeping her here was dulling her magic. When she smelled something wonderful, she looked down to see a pancake topped with a happy face made out of berries with whip cream, a side of scrambled eggs, and a sippy cup filled with orange juice.

"Ok, Luna, haha! I get it; this is a prank, isn't it!?" Celestia shouted, but nopony answered. She looked around, trying to figure out who made this for her?

"Well, I didn't make it," Luna yawned as she trotted, looking as confused as her. "But it does look delicious; it would be a shame to let this good food go to waste."

"Instead of worrying about the food! Can you let me out of this!" Celestia shouted back, wiggling to no avail; her rump was firmly planted in the plush seat.

Luna turned her head and tried using her magic to lift the tray, but that didn't work, she then tried using her magic to look for the enchantment, and then she saw a button on the side of the booster seat. She then pressed the button, and a voice replied, "error transformation is not allowed until all of Princess Celestia's meal is eaten by her. Note she cannot use utensils or her horn; she must be fed by hoof by another pony."

"Oh dear, it looks like somepony warped your throne; we'll have to play this game to get you out," Luna snickered.

"No way! I'm not going to be spoonfed! I can feed myself!"

Celestia saw some rubber fork and knife and tried to cut her pancake, but she felt a burning sensation on her hooves as if somepony slapped them. "Oww!"

"Bad filly, only big ponies use utensils."

Luna sighed, "look; obviously, we have to just do as the chair says."

"Fine!" Celestia frowned, glaring at blank air as Luna cut the delicious pancakes into small pieces and lifted them to her sister's mouth. The solar monarch's cheek turned to beat red as she took the bite. Thankful her sister didn't do anything goofy about it.

After Luna finished feeding her sister, she allowed her to drink down the cup of orange juice by herself until it was all gone. Celestia then felt a pang in her bladder and whined, "Luna, hurry and press the button!"

Luna did as her sister asked, pressing the red button. However, instead of releasing her, the chair began to morph. It was still hard plastic, but the tray had disappeared. It grew rounder around the mare's cheeks flushed red, feeling a gust of air around a hole around her rump as her tail was lifted up and cut, then the stub of what was left was tied with a little cute pink bow. The princess's cheeks flushed pink as she realized that this was more embarrassing than the booster seat! It was a foal's training potty!

"No way I'm using my personal bathroom!" Celestia cried out as she flapped her wings, but she couldn't move; she was stuck. Then a giant camera appeared in Luna's hooves as the robot voice said, "second transformation complete, the princess's potty throne. To proceed to the next transformation, please have the princess use her potty and take a photo."

"No bucking way!" Celestia shouted, then she whined as she felt soap suds pour out her mouth.

"Naughty foal, no bad words," the robot voice chimed, making Luna snicker and dawww. Meanwhile, Celestia had to swish her mouth with water; she spat it out into a cup that appeared in her mouth.

The princess of the sun then had her cheek pinched by her sister as she cooed, "awww, well, guess you don't have a choice."

Celestia tried to pull the T-shirt over her crotch as much as possible as she pleaded, "come on, there's got to be another way!" The princess was embarrassed and worried that she'll have to urinate in front of Luna!"

"I'll destroy the photo and this camera after this is done, ok? Just pee a little and let's get this over with," Luna explained soothingly.

The celestial monarch pouted as she started to pee into the potty. Still, then it grew from a tinkle to a torrent of urine, seeing she hadn't gone yet since raising the sun. Celestia's cheeks were a rosy red as she finished peeing, and Luna then cooed, "ok, raise your hooves and say I went potty!"

Without realizing what she was doing, Celestia did as her sister said, raising her hooves and exclaiming, "See, I went potty!"

"Dawww," Luna cooed as she snapped a few photos with her camera. The pictures then magically teleported and were framed on the walls nearby with "Celestia's first potty" labeled over them.

The princess of the sun was confused as to why she did something so embarrassing, and now the photos were on the walls! Celestia started to flap her wings and shout, "Hey, take those down now!"

Luna did use her magic to try to remove the photos, but they were glued to the wall. "Sorry, but I think they will stay until we finish this game."

Celestia glared at Luna, not trusting her now, as she snapped, "They better, and why did you make me say that stupid phrase!? You're enjoying seeing me be humiliated, huh!?"

"First off, no, I just was following the instructions on the camera, see," Luna turned the camera around and saw another rule "the caretaker has to make Celestia say and do something silly after she goes potty" "secondly, I didn't make you say or do anything it sort of came out, and I was hoping it'll catch you off guard. I do apologize. I'm not trying to make this worse for you."

It seemed Luna was telling the truth, but she still didn't fully trust her. "Ok, well, let's just get to the next transformation."

"Ok," Luna said as she pressed the button. The chair changed once more, with the seat still being hard plastic, but it was now shaping into a desk made for preschoolers with a wide pink plastic table laid out in front of her. Covering the table, there was a box of crayons, some glue sticks, a box of colorful macaroni, a box of popsicle sticks, and a container full of glitter. Celestia also found she was wearing a pink denim play dress with random paint splotches.

Luna snickered, putting a hoof to her muzzle. "Oh look, arts and crafts, remember those, sister?"

"Ugh, don't remind me! Starswirl used to make fun of my macaroni art all the time."

The voice interrupted the two, "Now Princess Celestia will make her sister a drawing with crayons and then an art creation her caretaker Luna will assist if necessary."

"Assist? What does that mean?" Celestia scoffed; she decided the first thing to do was draw a sun on some construction paper. But as she got the paper out, she turned to the crayon box. Oddly enough, she seemed to forget the names of the colors. She was too embarrassed to ask for her help as she should know her colors being over a thousand years old and a princess alicorn. But the information seemed to not be in her brain anymore!? "L-luna, I um, I need help with colors," she said sheepishly.

"Oh dear, this chair probably messed with your memory and intelligence. Ok, what are you trying to draw?"

"As..s..sun…" the princess squeaked with her cheeks flushing red.

"Ok, well, I think you'll need bright colors like yellow and orange," Luna explained as she took the two crayons matching the colors she described. "This one is yellow, and this one is orange."

Celestia nodded as she took the crayons with her mouth, and then she blinked, seeming to forget the shape of a sun. "um… what's the shape of the sun?"

"It's a circle," Luna gestured with her hoof.

A whiteboard appeared behind the princess of the night as she took a marker and drew a circle on the board. "See, that's a circle; it's round and has no sides."

Celestia nodded as she went to work; she did her best by drawing a sloppy circle with a yellow crayon. The princess then scribbled orange and yellow crayons together over the picture. It must've been half an hour before Celestia's finished as she held up her work. "Ok, I'm done!"

Luna looked down at the drawing with a smile; she clapped her hooves and cheered, "Oh, very good, Tia." The younger sister couldn't resist patting Celestia's head.

"What's my grade?" Celestia asked with her cheeks flushing red for some reason; she wanted to see how Luna thought of her drawing.

"Oh um…A! Your circle needs work, so you don't get a +, but the color is right, and I love how you tried to spell your name." Luna giggled, seeing Celestia's name written as "SeleStya" the throne must have regressed her sister's mind to a preschooler's.

"Yeah, I haven't learned my letters and numbers yet," the princess admitted shyly.

"Awww, it's ok, we'll get there; you're only in preschool; you learn that stuff in kindergarten," Luna said, giving her sister's nose a boop. "The chair said to make macaroni art as well. That will be messy for sure."

Celestia nodded her head as she got the glue and squirted it all over another piece of construction paper; she then looked up at Luna and asked, "um… what's your coat colored called?"

"it's a dark blue sweetie," Luna whispered as her cheeks flushed a little seeing that Celestia took darker colored macaroni and started liking them on the glue puddle. The princess of the night realized she was making a picture of her! Celestia then took popsicle sticks for the legs, glued them on the bottom of the misshapen pony she made, and then sprinkled sparkly silver glitter all over, finishing her work. Celestia held it up for her sister to see, proud of her work.

Luna smiled at the artwork as it appeared on the wall next to the previous one. "Hehe, aww, your acting adorable," she said, pulling the lever that had appeared, no doubt, the next phase of this rather odd game.

The chair morphed once more, keeping the pink hard plastic but now the tray was filled with a small teapot, a small plastic sippy cup, and a slice of cake. Celestia squeaked as her play dress turned into a frilly princess-style dress with white frills hiding underneath that went around her waist. The princess gasped as a pink pull-up slid under her rump. Celestia did her best to pull the dress down to cover up the new garment.

"Now it's tea time for Princess Celestia! The little filly simply needs to finish all her tea and eat her cake."

Celestia adjusted her dress a little before asking, "um, big sissy Luna can ya help me? Dun wana spill my tea."

Luna nodded, "of course, this should be easy; you love cake and tea."

The princess of the night then poured the tea into the sippy cup and adjusted the top making sure it was tight. She then spoonfed her sister once more with the cake, letting her chomp down on it. (Luna also noticed Celestia's teeth were much smaller, and there were gaps as well) if Luna had to guess, the chair adjusted her "age" to be around a three to four-year-old. The princess, however, continued to feed her while Celestia just loved the cake; it tasted lovely being a mix of vanilla cake with strawberry frosting. She finished the slice of cake she popped the sippy cup into her mouth. As Celestia suckled, she squeaked, kicking about in her dress. She didn't care that she was revealing her pull-up with the fear of wetting herself being much more of the issue on her mind and shouted, "Luna gotta go potty!"

"Oh dear, does this thing go back to the potty throne or what?" Luna asked out loud; she tried pulling the lever again.

"Error, Princess Celestia has not finished all the tea."

"So what? I doubt that pull-up can handle a grown mare's full bladder." Luna snapped back.

The chair began to sparkle suddenly as Celestia peered down, seeing that her pull-up was now a fluffy white mass of a diaper with her cutie mark printed on its front. The princess wiggled and whined, "N-nu, I big filly!" Although she felt like she couldn't hold it for very long.

"Seems like I'm the big sister," Luna said, taking the opportunity for alight teasing. "Now, just relax, drink your tea, and let it flow."

Celestia did as Luna said as she finished the rest of the tea, and her diaper began to fill the diaper with urine; the white padding swelled around her thighs as it felt warm and soggy.

Luna pulled the lever once the tea was made, watching the chair change as a new tray appeared with little plastic toys you find foals playing with. Various plastic keys and little things to flip and spin. The seat then went from a plastic to a cloth-like material as it enveloped Celestia and wheels appeared at the bottom with handles at the top. Buckles wrapped around the princess of the sun (with the princess squeaking as the straps were snug around her diaper), and as if by magic, her soggy diaper was replaced with a dry one with a Poof of foal powder. The only new item of her attire was a frilly yellow bonnet, and her princess dress was now a sunny yellow. But then Luna looked around and noticed the entire throne room was gone! They were out in some park with a nearby meadow and a pond filled with ducks. "Oh, we're at a park?"

Celestia stared around, worried she'd be seen in such a state, starting to worm in the stroller. Moments later, the little robot voice spike up. "No, you're still in the castle; it just looks like you're in a park; please have the princess go on a stroll. Luna, you're in charge; remember to watch Celestia and make sure she's happy."

"Ugh! Now I'm going from big sis to full-on mom," Luna grumbled as she saw that a giant yellow diaper bag was now around her chest. She went over to Celestia, patting her diaper, seeing it was dry and full of foal powder. "Ok, all dry what will calm you down…oh a pacifier!"

She plopped a giant yellow pacifier into the princess's mouth. She watched her suckle on it, which did soothe her whimpering. The little princess then began to bat around the toys as Luna went to the back of the stroller and began to push it with her magic. She technically wasn't moving, but it felt like she was with the scenery moving around them as they continued to trot. Luna's cheeks flushed red seeing ponies passing by waving their hooves; some even gave Celestia's diaper a pat, and she heard the padding crinkle!

"What is going on here?" Luna asked herself, being somewhat confused, but she continued; then she heard Celestia start whimpering. The princess then sniffed the air, and it reeked! She trotted around the stroller and saw her diaper was sagging a little and smelt foul.

"Ugh! No!" she then got a fresh diaper and some foal powder going about the change. Celestia was embarrassed yet felt comforted by Luna's presence and seemed to not mind. Thankfully it didn't take too long before she was all nice and fresh once again put back in the stroller. "Mmm, what next?"

Luna pulled the lever near the stroller again. The scenery unfolded as if they were screens going back into the stroller. Luna gasped, seeing the throne room now had a foam material on the ground and the walls covered with little suns on the wallpaper. The throne then turned into a giant white plastic toy; the tray was now designed with blinking-shaped lights that made noises as classical music played from speakers built into the chair. Overhead printed above the smiley face read "Baby's First Throne" by Hasbro.

"Oh my, that's one fancy baby toy." Luna snickered as she watched Celestia mindlessly bashing her hooves on the tray, seeming to have her mind regressed to that of a year old foal.

The princess of the night was feeling abit exhausted from babysitting her sister. She then sat down on a rocking chair that appeared out of nowhere and kept an eye on Celestia, seeing her immersed in her toy, getting praises as she pressed the colorful buttons and bounced on her padded tush.

Luna noticed a giant clock overhead with various "times" replacing the numbers from playtime to feeding time, nap time, and pickup time.

There was only one hand on the clock as well as it was stuck at feeding time. The playful, colorful throne started to gain height as it turned into a highchair with Celestia's dress now gone being left in nothing but her diaper and a pink bib with her cutie mark printed on it, tied around her neck.

"Oh, it's feeding time!" Luna chimed as she got up and trotted over; she saw on the tray a jar of mashed yams and a giant foal bottle filled with formula.

Luna took a deep breath as she took a rubber spoon full of the orange goop, sailed it over to Celestia's mouth, and cooed, "Ok, here comes the choo, coo train!"

The mare squealed as she opened her mouth, and she got a mouthful of the stuff as she mashed her mouth, getting the goop over her face and bib. Luna couldn't help but giggle at Celestia making adorable faces as she chewed on her meal. The princess continued to feed her sister, washing her face and keeping her clean.

"Oh, you're such a messy eater; there's more food on your bib than in your mouth," Luna commented.

Celestia just giggled and cooed as she booped Luna's muzzle; she just snickered and continued to spoonfeed her. Eventually, Celestia ate every last bit of food, and Luna wiped her mouth and Celestia's face with a foalwipe. Then the princess of the night lifted a bottle, placed it into her mouth, and watched as she chugged down the contents. Celestia greedily suckled the bottle making adorable gurgling noises as she did so, and Luna again hs to use a foal wipe to clean up the milk that dribbled from her mouth. Celestia grasped the bottle with her hooves, and Luna stood back and dawwwed, seeing the princess holding the bottle herself. The princess of the night took the camera and snapped a few pictures that ended up on the wall next to her being on the potty.

After the bottle was empty and Celestia was just sucking on air Luna saw her eyes were closed, falling asleep.

"Ok, I believe it's naptime," Luna cooed; she took the bottle out of her sister's mouth and took off the bib. The princess of the night then watched as the back of the chair became flat, lowering Celestia into a table-like surface. Then the furniture started to transform into a crib as the back of the chair slowly laid down with yellow bars appearing around Celestia. She was then dressed in a nightblue sleeper with Luna's cutie mark on the back flap where the princess's diaper bulge could be visibly seen. A mobile appeared overhead with little sun and moons swirled around Celestia's head as a soft nursery rhyme song came out.

"Hello, Princess Luna," the chair whispered, "now I know you're tired, but you need to stay up and watch the baby until she gets picked up."

Luna yawned, seeing at this point the silly throne was testing her. "Fine, but my sister will be normal after all of this, yeah? Because if she doesn't, I'll hunt down whoever did this."

"Oh, no need for threats; Princess Celestia will be a big pony tomorrow; I just thought she could use a nice break from all of her boring princess."

"Ok, Discord, just hurry your butt over here," Luna grumbled.

"Wait, how did you figure that out!?"

"I didn't; you just told me," Luna stuck her tongue out. "Also, who else would be powerful and crazy enough to do this to us? I don't have Twilight and her friends turn you back into stone because this was a lovely little day. But like I said, Celestia better not be affected by this in any way."

"Ok, ok, easy now, she'll be back to normal, ok! No need to have a tantrum."

Then, a word humming noise as Luna turned her head and saw a giant pink horseless carriage appear. Discord came out and opened the side door showing off a car seat. "Ok, well, I think it's pickup time."

Luna lifted her sleeping sister and helped strapped her into the car seat, making sure the straps were snug around her sister; she dawwed seeing Celestia was wearing nothing but a diaper and a bright pink T-shirt that read. "Sun Butt" The princess then tapped Celestia's diaper, seeing it squish beneath her hoof as she said, "well, she'll definitely need a change when you get back to your place."

"I know; I got my whole house babyfied for little Tia," Discord added. Luna popped a pacifier in Celestia's mouth before closing the door. She said, "ok, Celestia better back here by six a.m tomorrow."

"She will be, ok?" Discord scoffed as he got into the driver's seat.

Luna then turned to Celestia, still sleeping away, and cooed, "by tia, hope you have fun."

She stepped back as the minivan took off into a portal; everything was back to the normal-looking throne room, with all the embarrassing pictures now gone. Luna yawned and stretched her wings and trotted off out of the room to find her bed, where she planned to crash for the rest of the day.

Princess Celestia "The Younger Sister"

Princess Celestia woke up from what felt like a dream, the mare looking around her room and seeing that something felt off to her. The walls were decorated in bright blue wallpaper with sunny little suns printed all over the paper and looking like a child's nursery. The princess then slowly stepped out of bed, having to climb over tall white bars as she manueverd herself over the bars. The alicorn princess squeaked rather suddenly as she found her hooves sinking slightly into the foam flooring instead of her usual regal carpet. The rest of the room had also changed, looking like a large nursery themed just for her. Even her bed was surrounded by tall white plastic bars to resemble a toddler's bed with a mobile attached with spinning suns and moons attached to the object.

The last thing Princess Celestia remembered was being babied by Discord, but that was all a dream, right? She got rather angry that if the lord of chaos was still pampering her, she had enough and shouted. "That's enough, Discord! You turn everything back to normal right now!"

As the princess called out, the door to her room opened, as Luna strolled in with a smile. "Is my little sister awake?" She asked in a motherly tone.

"What are you talking about!? Luna, are you in on this!?" Princess Celestia snapped, but her flustered shouts only got dawws from the princess of the night. "Oh, looks like somepony is talkative. Can you say sissy lulu yet?"

"Huh?" Celestia asked as she was lifted up from the crib and gasped upon seeing her bright white diaper, minus the fact that the front of the padding was now stained yellow with little suns printed all over the padding.

The princess alicorn whined, seeing her diaper was soaked in her sleep as Princess Luna gave her pampered rump a few loving pats. "Oh, it's alright; you're not ready for potty training yet."

The lunar monarch cooed, moving the now younger sister to the changing table.

"Hey, what are you doing!?" Celestia squirmed about, but her body felt sluggish, and she seemed to have trouble moving correctly. She tried flapping her wings, but nothing happened. She then lit her horn, but the magic fizzled out, creating only little sizzling fireworks.

"Aww, you trying to do magic, how silly of you, "Luna said, going about the change with a soft humming. Celestia constantly wiggled as she seemed unable to control herself.

The princess started to whine and curse, causing Luna to pop a giant yellow pacifier in her mouth. "Alright, that's enough whining; let your big sissy finish your diaper change."

Celestia's cheeks turned crimson as she oddly held on to the pacifier with her lips giving it a suckle or two on reflex, distracting her long enough for Luna to finish.

Luna quickly finished powdering her sister's rump and strapping her up in some fresh padding. "Now, that wasn't too hard, huh?"

She asked, giving her sister's nose a light boop and watching the eyes cross. The princess sat Celestia on her diapered tush and cooed, "now raise your hooves for me."

The princess of the sun crossed her hooves across her chest and shook her head. "Nuh, uh."

"Oh, does somepony want a visit from the tickle monster, perhaps?" Without warning, Luna lifted a wing and started to tickle her sister's belly making her giggle and kick uncontrollably. Taking the opportunity, Luna lifted up Celestia's hooves bringing over an adorable little yellow T-shirt with a smiling sun. "There, I know how messy you get during breakfast. I don't want to get your coat or your pretty dress all dirty. After num nums, we can get a cute dress for you. How does that sound?"

Celestia whined lightly behind the pacifier, but there wasn't much she could do about it as she was lifted up and sat on the floor. No doubt she'd have to waddle her way to the dining room.

Luna then placed her sister on the ground as she took a Camera snapping a few photos. "Oh, you look so adorable. Do you want to walk, or do you wish for a stroller?"

The princess scoffed as she held her head up; even in such an embarrassing outfit, she'll walk on her own. However, when she took her first few steps, not only was she a bit clumsy but relatively slow at it, losing her balance with almost every step. It was like she didn't know how her legs worked. As she moved down the hall, Celestia slowly made her way to the door, which was now open. Seeing more of her castle made the princess blush to see the corners of the walls. With padded pink fabric, the carpet was all replaced with interconnected puzzle piece foam mats, and the walls were covered in pictures of her in diapers and wearing cute dresses. There was even a picture with Celestia's smashing her face in a birthday cake and one with her crying while sitting on her sister's lap. Even a few sized-up crude crayon drawings and hoof paintings implied she had made them. All of which added to her embarrassment of being in diapers and looking adorable.

She was then coming up the stairs but whined, seeing there was a plastic baby gate.

"Don't want you falling and hurting yourself, cutie," Luna cooed as she lifted her sister onto her back in her poofy padding.

They trotted down the steps with Celestia shouting, "I can go downstairs!" she kicked and whined again, hating being patronized.

"Now, we can practice stairs later; we got to get you fed and have you raise the sun, sweetie," Luna explained motherly, not bothered by her fussy behavior.

They soon arrived at the kitchen, where Celestia was strapped into a toddler booster seat. Luna had already breakfasted and prepared a bowl of oatmeal with berries and cream, some tea in a sippy cup, and a few slices of apples.

Spitting the pacifier out, the princess put a hoof in her mouth and felt her teeth were much shorter, and there seemed to be gaps.

"That's the right, cutie; you still have your baby teeth, but we can start feeding you harder foods like apples, but you gotta chew slowly," Luna explained as she scooped the oatmeal into her sister's mouth. Celestia tried to avoid being fed in such a manner dodging her head from side to side. Luna, however, started to make some funny faces, making the sun princess giggle uncontrollably, allowing her sister to slip a rubber spoonful of the brownish goop. The princess of the sun gulped the foal food down her throat, and soon, she had more of it shoved into her mouth. Princess Celestia didn't know why but it was like her subconscious was taking over as she continued to chomp down on the baby oatmeal making a mess all over her face and T-shirt.

"Awww, such a messy eater. Why do you think I dressed you, hmmm? Your beautiful white coat would be covered in oatmeal by now," Luna snickered as she wiped her sister's face.

Celestia pouted but let Luna wipe her face without a fuss. She then plopped the plate of apple slices and the sippy cup of tea on her tray. "Now, you eat this while I get some cleaning done?"

The princess grumbled, "fine." Celestia looked down at the slices and started to chomp on them slowly, seeing that it was much harder to eat than the oatmeal. She looked at the sippy cup of tea and suckled it down, loving how it tasted together. Celestia continued to snack away while sipping her tea; when she finished, Luna unstrapped around the princess and placed her down. "Such a good baby, Tia; you ate all of your apple slices."

Luna bent down and hugged her. "Now come on, we should get you all prettied up so you can raise the sun!"

Celestia nodded, so embarrassed that she was getting excited at being praised for such a simple task as eating. Of course, dressing up to raise the sun made sense; she had to be pretty for the sun, after all.

It took about an hour, But Luna had her sister bathed, her teeth brushed, and had her use the training potty. Luna then strapped her sister up in a fresh diaper around her rump, had her mane combed, and dressed her in a sunny yellow princess dress. The princess of the night then had Celestia's mane tied up in cute yellow satin bows, with one being tied around the base of her tail and at the end of it. Celestia was now looking at her reflection in her nursery, looking foalish, unable to recognize the regal princess now covered in such foalish attire. The diaper still poked out from the skirt of the dress like a constant reminder of her foalish status. Celestia assumed this had to be a dream but the idea that this could all be real lingered in her mind as well.

Luna was excited as she snapped pictures of her with a camera. "Oh, I can't wait to show these to Twilight."

"Huh, who, Twily?" Celestia asked, but Luna must've only heard "Twily" and dawwed, "aww, I gotta tell Twilight she said her name too! Oh, you're just so precious. Now come on, we're already late."

Luna lifted her sister onto her back and trotted out of the nursery and through the castle. They eventually came upon what used to be Celestia's palace garden. But it was now a giant playground with a jungle gym, seesaw, sandbox, and even a baby pool.

The princess of the night trotted off through the park and came to a grassy hill. It was still night out with the moon overhead shining down on them. Overlooking the hill were tons of other ponies, with the mares all dressed in dresses and the stallions in suits, all sitting quietly waiting for her.

Luna planted her sister on the hill and said to the crowd, "thank you for your patience; we had some trouble getting Celestia ready, but she's here and ready to raise the sun."

The crowd grumbled some clapped as most of the ponies looked grumpy, having to wake up so early.

Luna then turned her attention to her sister and whispered, "Now, flying is still hard for you, so I just want you to raise your forehooves into the sky and light your horn to raise the sun, okay?"

Celestia blushed as she did so, her horn alight with her golden aura. Moments later, she felt Luna grab the padded alicorn from underneath her forehooves and lift her off the ground, raising Celestia into the air. Thus, the sun did rise along with the princess and continued to rise until the star was on its way across the sky. Despite having done this plenty of times before, she felt a sense of pride wash over her.

Luna nuzzled her sister as she hovered back to the ground, cooing at her. "Oh good job, tia, which a good sun raiser, yes you are!" she gave the cheek a pinch. "Now, how about some court time? And do some big princess things."

Celestia giggled as she bounced up and down, "am I a big princess!?"

Luna gave her sister a diaper check, padding a few pats feeling it was slightly wet. "Well, almost; we need to get you potty trained one of these days."

The Solar princess's cheeks flushed pink, seeming to remember how many failed attempts at potty training she had over the years. She could only wonder if she'll be stuck in diapers forever.

As Luna took her sister's hoof and led her back to the castle, she cooed, "you don't worry about that right now; we'll get you potty trained eventually. But you need to be on your best behavior while we're in court, so I'll be having you doodle in your coloring books, okay?"

"Yes, Lulu," Celestia chimed obediently as she waddled behind her sister, not even caring that she was in diapers; in fact, all she could think about was coloring in her favorite coloring books! The elements of harmony sets were fun.

"I bet you'll even use the right colors this time," Luna teased as they walked into the palace proper, moving along the throne room in no time.

Celestia stuck out her tongue. "But different colors are the fun part."

Entering the throne room, Celestia saw her throne was much different than her regal seat of power. It was now made of hard white plastic with a pink foam seat for her rump and back. She had a plastic tray attached to the seat where she had a coloring book open with some crayons. Luna chatted with the noble ponies who came by to talk about big pony stuff. The words just went over Celestia's little head as she went about her day coloring pictures of ponies. She was sure she recognized some of them, Twilight, Rainbow Dash, Pinkie Pie, etc... but she didn't know from where?

One of Luna's friends, Fleur, trotted over, and soon the two began chatting.

"Oh, princess Celestia is looking so well behaved today."

"Yes, she is. I wish she were always this easy; Faust knows it makes getting through the morning much harder when she's fussy."

"Oh, and you stayed up all night dreaming walking? How about you get one of your maids to watch her during the day? You must be so exhausted."

"It's fine, really; I love babying my little sister; I'll get some sleep when she takes a nap and puts her to bed. Besides, I try getting her to bed early. Trust me; she's a nightmare when she stays up late."

Celestia blinked, looking over the two ponies talking. She couldn't help but wonder if they were talking about her and said, "I dun wanna go to bed early! I wanna watch Lulu raise ta moon!"

"Oh, she's so precious!" Fleur cooed as she pinched Celestia's cheek.

Celestia felt slightly embarrassed when asked, "what does precious mean?"

"Dawww," both mares said out loud as Luna explained, "well, precious means you're just a sweet little angel. We are almost done for the day, but I need your signature on something."

The princess of the night then took out a scroll and laid it out for her. "I need you to sign the bottom of the scroll."

Celestia scrunched the diaper between her legs. "But I dun know how to write!"

"I'll help you," Luna whispered gently as she lit her horn and levitated one of the crayons into Celestia's hooves. "Now, let's start; the first letter is P."

The princess of the sun watched her hoof was moved by Luna's magic, and she wrote out her name one letter at a time. P-r-i-c-e-s-s C-e-l-e-s-t-i-a. Once finished, there was a sloppy scrawl in pink crayon. Celestia flapped her wings with pride as she bounced up and down on her diaper. "I did it! I wrote my name!"

Luna bent over and ruffled her sister's mane. "Yes, you did…sort of… we'll get you to learn the alphabet one of these days."

Celestia nodded as she chirped, "ya gonna enroll me in preschool, right!"

"Yes, we are! Bet you're excited to start, huh?"

"Yeah, can't wait!"

Fleur put a hoof over her chest. "Oh, she's just such a cutie pie!"

"Yes, she is; well, I think we should go on a stroll before bed," Luna cooed as she took Celestia from her padded seat and plopped her down on the floor.

Fleur then trotted over and gave Celestia a kiss on the cheek. "You be a good girl and listen to your big sister, okay?"

"Yes, Mrs. Fleur!" the princess chimed back as she raised herself and hugged the mare. Luna stepped back, letting Fleur nuzzle her sister as she cooed, "Oh, you got to let me babysit her one of these days."

"We can arrange for that tomorrow nig- I mean tomorrow…." Luna stammered.

Celestia blinked as she looked over and asked, "tomorrow night? Am I gonna have a sleepover!?"

"Maybe later; let's get you in a onesie, some lunch, then go on that stroll!" Luna quickly explained.

"Yay, Park!" Celestia cheered, bouncing on her bottom.

After Celestia was changed into a fresh diaper and a bright yellow onesie with "spoiled princess" printed on the chest and a rather adorable buttoned flap on the back. She was now sitting back on her toddler seat in the kitchen, chopping away on some cut-up pancakes as Luna spoon-fed them into her sister's mouth. Each time Celestia chomped down on some cut-up pancakes, her sister placed a giant bottle of formula into her mouth to wash it down.

"My goodness, you're such a messy eater." Luna giggled, seeing syrup and whipped cream all over Celestia's face.

The princess wiped her face with her messy hooves, making it worse! Luna couldn't help but giggle as she wiped her sister's hooves and face with foal wipes.

Celestia, however, didn't mind as she was used to being cleaned up by her sister Luna. She then asked, "Lulu can I help you make pancakes next time? I wanna help."

"Oh, well, you can help me stir the batter; I can't have you near the stove," Luna explained in a motherly tone. "But thank you, dear, now do you feel the need to go potty?"

Celestia's cheeks flushed red as a smell reeking from the diaper below hit Luna's nostrils. "Ugh again!?"

"Sorry,"

"It's okay, sweetie; after your change, we'll go to the park," Luna sighed, mumbling about dealing with messy diapers.

Celestia, of course, was rather patient as Luna had her lay down on a changing mat and had her rump cleaned. After her change, the button hatch of the onesie was buttoned up. The princess was plopped in a stroller and strapped in. Celestia kicked about in excitement as the princess of the night went behind the stroller and cooed, "alright, let's get going."

Luna then pushed her sister out of the castle and into the streets of Canterlot! Celestia was greeted by her subjects, waving their hooves and cooing at her. They called her sweet names; some even gave her diaper rump a few pats. Celestia couldn't help but bounce up and down in excitement as they continued through the streets. They then came by a cake shop, and the aroma of cake wafted, overfilling the princess's nostrils. She squirmed and gave "mmmph!" sounds as Luna looked down with a puzzled expression. She then looked at the bakery and cooed, "oh, you want cake! Well…you have been a good girl. I think you deserve a treat."

"Yay, cake!" Celestia squealed, flapping her wings as they went into the shop. Luna picked out a lovely little cupcake with pink frosting and sprinkles. She then placed it in Celestia's hooves as she shoved the cake into her face, getting cake and frosting to splatter as she chomped on down.

"Oh my!" the shop owner cried out loud, somewhat surprised at Celestia.

"Yes, she's a messy eater," Luna explained as she wiped her sister's mouth, not really surprised about cleaning her up. She continued to push her down the street, with the solar princess continuing to shove the cupcake into her face. When it was all finished, Luna levitated a bottle of formula into her hooves and watched her suckle on it with a smile.

They then continued to trot down the streets as the princess of the night hummed a tune out loud. It wasn't long until they made it to the park, where Celestia was unstrapped and was set loose upon the grounds. There were many things to play with, from the slide to the pirate ship play equipment. There was even a tire swing or two. Celestia got rather excited as she wanted to try out everything. Still, as she was going to run off, she was held back by her sister's magic.

"Hold on, diaper check!" Luna chirped as she gave her sister's padding a few pats, "good, all dry and clean, now go on and play but stay in the park; don't wander off."

"Okay big sissy lulu!" Celestia squealed as she flew off to the park and started to slide down slides, swing on the tire swings, shovel sand in the sandbox, and just ran around bouncing up and down, flapping her wings. Luna just sat back and watched her sister play like a little excited foal going from one activity to the next. It wasn't long until the sun began to set, and Luna got up from the bench. "Alright, Celestia, diaper change, then bed,"

"Awww, I wanna stay in the park!" The padded princess whined as she waddled over to her sister, who had just ruffled her mane. "We can come back tomorrow? Next time I'll maybe find a playmate."

She then settled Celestia onto the park bench and unbuttoned the onesie as she revealed her soggy bottom.

"My goodness, such a super soaker. I'm surprised you didn't leak." Luna teased as she went about the diaper change; Celestia replied, "I was having too much fun. I forgot to ask you to take me to the potty."

"Maybe next time," Princess Luna chimed as she gave her sister's rump a fresh layer of foal powder and a diaper around her. After securing the button hatch

"Okay, lulu," Celestia yawned as she stretched her wings. Luna then strapped her sister into the stroller and trotted off through the streets. The princess kicked about in her new padding, feeling so relaxed she yawned and stretched her tired limbs. Just then, Celestia felt a pacifier slip into her mouth. The solar princess had a wonderful day, and she loved her big sister watching out for her, changing her diapers, and taking her to the park. As Celestia drifted to sleep, the last thing she remembered saying was, "good night, mama."

There wasn't a response, with Luna's face turning a beat red. Did her sister just call her mama!?
