Everypony wants to baby Princess Celestia

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!?
