Celestia had just walked out of Fluttershy's cottage, "cewestia, we go to get my tings from castwe?" twilight asked

"Sure, but what thing do you need to grab?" Celestia asked

"Well, just some tings." Twilight said

"Okay." Celestia said as she turned to the castle of friendship

After about ten minutes they got there, "should I knock?" Celestia asked twilight

"Um, why you asking me." twilight asked

"Well, it's your castle," Celestia said back

"Twue, I guess knock." Twilight said, then Celestia knocked on the castle door after about a minute or two spike opened the door

"Oh, hi princess Celestia, Twilight's not here right now, I don't know where she is right now." Spike said

"Don't worry about twilight, she's right here." Celestia said as she pointed at the foal in the stroller

"Is that twilight?" spike asked

"Yep, hi spike." Twilight said

"H-hi twilight, what happened to you?" spike asked

"Wong story." Twilight said

"Okay... then why is Celestia here?"

"Once again, it's a long story." Celestia said

"Well come in, come in." Spike said as she let in the two princesses in

"Well what's going to happen to Twilight?" spike asked

"She's going to come to canterlot with me-" Celestia started but was interrupted by spike

"So you can find a cure."

"No, there is no cure, she's going to come to canterlot and be raised by me," Celestia said

"Oh, so why are you here?" spike asked

"Twilight said that she needed to get a few things." Celestia said as she let the foal out of the stroller

"Yea, me just need to get to wood, you help spike?" twilight asked

"Sure twilight, piggyback ride," Spike said as he picked up Twilight and put her on his back

"Hey, where stawwight?" twilight asked

"She's in her room, we could go there if you want." Spike said as he walked down the hallways of the castle

"Yea, I wanna see hew," Twilight said as she held onto spike

"Okay." Spike said as he turned around

Starlight was laying down in her room when she heard a knock, "who is it." starlight yelled from her bed

"Its spike, and um... Twilight." Spike said

"I thought that Twilight was missing." starlight said as she opened the door

"She was, but now she's right here." Spike said as he grabbed the foal off of his back, then showed starlight

"Hi stawwight, it twiwight." Twilight said

"Twi-Twilight that's you?" starlight said as she grabbed the foal, then she shut the door

"Yea, it's me." Twilight said

"What happened to you?" starlight asked

"It wong story, but I guesse me teww you, wight now." Twilight said

"Okay, let's sit on my bed." starlight said as she walked to her bed, and put twilight on the bed, then sat down herself

"Okay let me get this straight, you helped Fluttershy by watching rainbow dash, who is a foal, but you did a spell, now you're stuck as a foal, with no magic." starlight said

"Yep." Twilight said

"You know sometimes I hate magic." starlight said

"Why?"

"Because, you could be trying to do one spell, but it does something totally different." starlight explained

"Yea, I guess." Twilight said, then a faint smell appeared, starlight instantly know what it was

"Smells like someone needs to be changed."

"What, no... I no need t'hange!" Twilight yelled, even know she knew that she did

"Twilight, do you actually think that I would fall for that?" starlight said as she picked up Twilight, the smell got even worse

"I sowwy, I no know that I need to go potty." Twilight said at the Verge of crying

"Don't be assumed, I kind of figured that you would need to go... potty soon anyways."

"How?" twilight asked

"Well number one, you were squirming a lot, and number two, if you didn't need diapers, then I don't think that you would be wearing one." starlight explained

"That... make wot of sense." Twilight said

"Now let's go get you in a new diaper." starlight said as she walked out of her room, and to the main living area of the Castle

"Hey starlight, why is your mane so soft?" Twilight asked as she played with starlights mane

"It's probably the conditioner I use." starlights said with a small giggle

"Why you giggwing?" twilight asked

"Oh, it's nothing."

"Well, it something."

"Fine, its just that your so cute as a foal." starlight said

"I am?" twilight explained

"Yes you are." starlight said

"Otay, I'm cute, but no caww me that." Twilight said

"Okay, now where am I going to get a few diapers." starlight said

"You go to Celestia." Twilight said

"Wait, Celestia is here? I haven't seen her since the time I went to canterlot."

"Oh, yea, the ting with the map." Twilight said

"Yep, let's go to um... The map room?" starlight said as she turned to the map room

"So Twilight, what's your favorite thing about being a foal?" starlight asked as they walked into the map room

"Um, I say, not having to do anyting." Twilight said, then both twilight and starlight saw Celestia sitting in rainbow dashes chair, "CEWESTIA." twilight yelled happily

"Hi Twilight, hello starlight, what's wrong?" Celestia asked

"Twilight had an accident, and needs to be changed, I would have changed her, but I don't have any diapers, so I wouldn't have anything to put her in." starlight said

"Okay, just sat her on the table," Celestia said, then starlight put twilight on the map table

"Hey Celestia, what exactly are you doing here." starlight asked, she knew that Celestia knew that Twilight was a foal, but she didn't know why Celestia was there

"Oh, I though that Twilight would have told you, she's going to canterlot with me, so I can raise her, unit she's an adult again." Celestia explained as she untapped twilight's diaper

"Oh, she didn't tell me any of that."

"I no get that far yet." Twilight said, even know it was an excuse

"Sure." starlight said looking at the foal, then she looked at Celestia, "is there a cure for what happened to Twilight?"

"No.... well there is, but Twilight would have to do the cure, but she doesn't have control of her magic, so she can't do the spell," Celestia explained as she wiped twilight

"Oh, well I'm sure there's another cure."

"Trust me there isn't, I've looked," Celestia said as she put a new diaper on twilight

"When you have time to wook?" Twilight asked as she sat up

"Let's just say, you take a lot of naps," Celestia said

"I no take a lot of naps." Twilight said as she crossed her arms

"Okay, well we should be leaving," Celestia said

"Wait, I no got my tings." Twilight said

"I thought that's what you were doing for the last hour," Celestia said

"Don't worry, I can take her to go grab some stuff." starlight said as she picked up Twilight, and walked to Twilight's room

[Hr

"Okay Twilight, what do you need to grab out of your room, or would it be your old room?" starlight asked herself

"Just few books, and few other tings." Twilight said as she started to look around her old room, it was now huge to her

"How about this." starlight said as she hoofed a book to Twilight, even know twilight couldn't read, she knew what the book was

"This is book sunset shimmer talks me with." Twilight said as she grabbed the book

"So it's important."

"Yep, very important." Twilight said well nodding

"Then I don't think that you should have it, as a foal at leadt." starlight said as she grabbed the book from twilight

"But... But, WAAAA!" Twilight yelled as she started to cry, "IT MY BOOK, I WANT IT!"

"Clam down twilight, here, the book." starlight said as she put the book by twilight, but twilight just hit the book away

"WAAA!" twilight yelled again, then Celestia ran in the room and picked up Twilight

"Shh, Shh, its okay twiligit's it's all better." Celestia said as she rocked twilight back and forth, after about ten minutes, Twilight stopped crying, and had fell asleep, "what happened?"

"I don't know, we were just looking through twilight's books, then we found this book." starlight said as she hoofed the book to Celestia, "then twilight told me how important the book was, so I took it from her, and she started to cry." starlight explained

"Well I agree with what you did because this is a very important book, but you don't just take something from a foal, you have to ask them if you could have it, or they freakout, like you just saw."

"O-Okay, but I thought that she only looked like a foal, and used the restroom like a foal, but not act like a foal."

"Its the spell that she used to make her a foal, it doesn't just make someone's body the age they desire, it makes there mind the age they desire too," Celestia explained

"Them why can she still talk?"

"Its magic, it doesn't explain everything about a spell, just the important parts."

"So you have no idea why she can talk."

"Nope, not a clue." Celestia said well blushing

"Well, let's just pack a few of her things, then you can go." starlight said as she grabbed a few things of twilight's and put it in a beg

"NO, ME NOT CUTE!" Twilight yelled as she woke up

"Oh hi there sleepily head," Celestia said as she picked up Twilight

"Hi Celestia, were awe we?" Twilight asked as she rubbed her eyes and looked around

"I'll tell you as soon as I change you," Celestia said as she walked to a changing table and put twilight on it

"Otay, I went potty weww I asleep, that's first," Twilight said to herself

"It is? well at least it wasn't that bad," Celestia said as she untapped twilight's diaper

"Celestia, where awe we?" Twilight asked again

"Were on a train to canterlot, it's not that far now, just about ten minutes," Celestia said as she threw away twilight's old diaper, then put a new one under twilight's flank

"Celestia, do you know how wong I asleep?" twilight asked

"About an hour, why?" Celestia asked as she tapped the side of the diaper on twilight

"I just wanted to know." Twilight said as she sat up, "Celestia, remember the nickname I had for you when I was a foaw?" twilight asked

"Yes, you used to call me Tia, because you said Celestia was too hard to pronounce," Celestia said

"Well, Cewestia really hard to pro- pro- say, so can me caww you Tia again?" twilight asked

"Yes twilight of course, but why did you wait this long to ask me?"

"Me thought you get mad at me."

"I wouldn't get mad at you for asking a simple question, especially if its to help you."Celestia said as she picked up Twilight and started to hug her

"I wove you, Tia."

"I love you too, Twilight."

****

Twilight was in a car seat in the seat next to Celestia, they were still on the train to cantorlot, "Tia." Twilight said trying to get Celestia's attention

"Yes, Twilight?"

"we thewe yet?" twilight asked

"No silly, but were close," Celestia said

"How close?" twilight asked

"About five minutes, then we have to get onto our chariot to the castle." Celestia said

"Otay, and what time is it?" Twilight asked she knew it was the day, but she didn't know the exact time

"Its one in the afternoon," Celestia said

"Me thought it was there," Twilight said

"Really, well are you hungry twilight?" Celestia asked

"Yea awittwe bit," Twilight said

"Luckily I made a bottle before we left your castle," Celestia said as she grabbed a bottle she had in her beg, then hoofed it to twilight

"Yep, but isn't there a dinner cat?" Twilight asked as she grabbed the bottle

"Yes, but I don't think they have bottles and foal food," Celestia said

"Twue," Twilight said as she started to drink the bottle

"Twilight, do you think that you'll like living as a foal?" Celestia asked

"Yea, I wike awmost every part of it." twilight said

"What are the parts you don't like, so I can try to fix it?"

"I don't wike wearing diapee's and i don't wike not being able to eat weal food.... Oh yea, I don't wike sweeping a crib." twilight said

"Two of those thing we cant avoid, but how about this, you can sometimes sleep in my bed with me." celestial said

"Otay, that fine." twilight said, then the train stopped

"Lets go." celestial said as she picked up the car seat with the foal in it, then the bag of twilight's things

"Why you no take me out of the ting?" twilight asked as celestia walk out of the train

"Because, were going on a chariot in a minute, and it would be easier if you would just stay in the car seat until we get to the castle." celestia explained

"cewestia, you tink that we should call my pawents?" twilight asked

"Well if you want to see them, then I can." celestia said as she walked to the chariot

"Weww, yea, I haven seen them in a few weeks, I miss them." twilight said

"Okay I'll call them tomorrow." celestia said as she put the car seat in the chariot then sat down herself

"How was your trip, princess." the guard that was driving the chariot asked as he started to drive towards canterlot castle

"It was fine." celestia said

"Who's this little one?" the guard in the chariot asked as he tickled twilight stomach alittle, which made her giggle

"This is princess twilight sparkle." celestia said

"Wait, I though that princess twilight sparkle was a adult?" the guard said

"She was, its a long story." Celestia said

"O-Okay?" the guard said

The rest of the ride was silent, twilight fell asleep, once they got to the castle, celestia got out of the chariot, then unstraped twilight and put her in a pop-out stroller and put the top down, then walked to the castles front gate

"Hello princess." the guard said as he opened the gate

"Hello, may you please contact princess twilight sparkle's parents, and princess Cadance, tell them to come here tomorrow." celestia asked the guard

"Yes ma'am." the guard said

"Thank you." celestia said as she walked into the castles, where luna was waiting for her

"Hello Sister, did your trip go well." Luna asked

"Yes Luna, and I've got a big surprise." celestia said as she pointed a hoof at the stroller

"What is it, and why do you have a stroller?" Luna asked as she tried to open the stroller, but celestia stopped her

"Come to my room and I'll show you." celestia said as she and Luna walked to celestia room,

"What's the surprise." Luna asked

"Okay, ill show you." celestia said as she opened the top of the stroller to show the still sleeping foal, "this is twilight."

"Aw, she's so cute." Luna said before celestia could say anything else, "wait, wasn't twilight a grown-up mare?" Luna asked

"Yes, but a spell was casted, and now twilight's a foal, and she has no control over her magic." celestia explained

"I see, what are we going to do?" Luna asked

"We raise her." celestia said, then she walked to the door and opened it, to see a guard, "excuse me, sir."

"Yes princess?" the guard asked

"May you please have the Royal interior designers make a nursery down the hall." celestia asked the guard

"A nursery, ma'am?" the guard asked confused

"Yes, a nursery."

"Yes ma'am, right away." the guard said as she ran away

"Okay now that's done." celestia said as she went back into the room to see Luna holding twilight, Luna instead noticed Celestia looking at her

"She needs to be changed, but other then that, she's adorable." Luna said as she held the foal

"I'll change her when she wakes up." Celestia said with a small giggle

"What's so funny?" Luna asked

"Its just that, I thought that you would be more surprised when I showed you twilight." Celestia explained

"Well I kind of already knew." Luna said as she looked at Celestia

"How, did you look through my mail again?"

"No sister, I knew because of what twilight Dreamt about." Luna explained

"Meaning?" Celestia asked

"At night I would be going through everyponies dreams, then I would get to twilight's dream, she would usually dream about falling a test or something else, but starting a few nights ago she started to start to dream about more silly things." Luna explained

"Like what exactly?"

"Things that would only make sense if a foal would say it." Luna said as she tickled twilight's belly, twilight then woke up giggling

"Hi twilight." celestia said as she grabbed the foal from her sister

"Hi Tia, wha going on?" twilight asked as she rubbed her eyes

"Nothing right now, were just in my room." celestia said

"Are you not going to even going to bring me up sister?" Luna said

"Wuna?" twilight said as she tried to look at Luna from celestia's arms, but she was faceing the wrong way

"Yes twilight, its me, Luna." Luna said as she grabbed the foal from celestia

"Wha you doing hewe?" twilight asked

"I live here, don't i?" Luna asked

"Yea, but what
you doing in Tia's woom?"

"Celestia was just showing me something." Luna said

"I want to see." twilight said

"Well we can't show you sweetie." Luna said, twilight might not have liked being called 'sweetie' but she decided not to say anything about it, she really just wanted to know what celestia showed Luna

"Why not?"

"Because we would need to get a mirror." Luna said thinking twilight would be able to guess what she was talking about

"Why would you need a miwwow?" twilight asked

"Because its you silly!" Luna exclaimed

"Oh, I get it now." twilight said as she jumped out of Luna's arms and onto the bed

"I'll be right back Luna." celestia said as she walked out of the door, to fine the same guard from earlier, "hello again."

"Hello ma'am." the guard said

"May you please get me a pack of silly-filly diapers size 1?"

"May I asked why ma'am?"

"Princess twilight sparkle has been turned into a 1-year-old foal, and she can't control when she has to go-" celestia started but was stopped by the guard

"I understand ma'am, is there anything else that you need me to do, or get?" the guard asked

"Yes, can you please inform the rest of the staff that twilight has been turned into a foal."

"Yes ma'am." the guard said as he ran off

"Now that's taken care of." celestia said as she walked back into her room, were Luna was tickling twilight

"Stop it wuna, pwease!" twilight yelled through her giggles

"You heard her lu-lu." celestia said

"Oh so were calling each other foalhood nicknames, Celie." Luna said as she stopped tickling twilight

"If you want to, I was just making a joke out of it, but I don't care if we do." celestia said

"So you were going to make a joke out of our memories?" Luna asked a little hostile, twilight could fell the hostility

"Luna I was just playing around." celestial said as she backed up

Luna wanted to yell, but she looked at twilight, who was scared, "We'll talk about this later, when you know who falls asleep." Luna said as she tried to walk out the door, but was stopped by celestial giving her a hug

"I'm sorry lu-lu." celestia said as she hugged her younger sister

"Its alright Celie." Luna said as she hugged celestia back, after about a minute of hugging, Luna left the room, leaving twilight and celestia

"Wha just happened?" twilight asked

"Luna just got alittle mad." celestia said as she sat down next to twilight

"But she seemed weally mad, Tia." twilight said

"Just don't worry about it." celestia said, then the guard with a pack of diapers came into the room

"Ma'am the package of diapers you requested, I also bought a pack of wipes." the guard said as he put pack of diapers and wipes on the bed

"Thank you." celestial said, the guard left

"Why do we need those?" twilight asked

"We need them Because you need to be changed, you didn't notice?" celestia tasked

"No." twilight said, but then after celestia mentioned it, she notice

"Well just lay back with your feet in the air." celestia said, and twilight did just that

"Twilight, are you alright?" celestia asked as she untapped twilight's diaper then throw it away, she was worried because the foal have her normal smile, but she wasn't sad

"Just tinking." twilight said as she was wiped by celestia

"About what sweetheart?" celestia asked as she throw away the used wipes, then put a new diaper under twilight's flank, twilight didn't care if celestia called her sweetheart, or sweetie, but it felt weird when Luna called her that stuff

"About why wuna was mad." twilight said as the diaper's sides were tapped and she sat up

"twilight you don't have to worry about that, me and lu-la are going to talk about that." celestia said

"What awe with those nicknames? Cewie, wu-wu?" twilight asked

"What's with the nickname Tia?" celestia asked joking

"Hey, I have a weason, cew... cewest.... cewestia hawd to say." twilight said, she was surprised that she managed to say 'celestia' again

"Okay, so what's wrong with me and Luna having nicknames for each other?"

"Nothing I guess, I just wanted to know why." twilight said,

"Okay." celestia said then the guard from earlier came into the room

"Princess, the nursery you requested is finished, would you like to see it?" the guard asked

"Yes, and what is your name, sir?" celestia asked

"My name is flash sentry ma'am." flash said

"Wait, fwash sentry!?" twilight asked

"Yes... ma'am." flash said

"Do you know him twilight?" celestia asked

"Not exactwy." twilight said with a blushed

"Okay well lets go." flash said as he lead celestia with twilight one her back to the new nursery
