Just along for the ride

Starlight pouted intently as she curled up as Spike’s grasp just barely being held in his arms. Her chubby bottom was supported by a thick white diaper taped snuggly in place and adorned with tiny rattles printed along it surface. She blushed as she reflected on how she’d gotten into this situation. What had started as a simple sleepover had turned into a magical scavenger hunt when herself, Twilight, and the princess’ old Canterlot friend Moondancer, had been unwillingly sucked into an enchanted gamebook. Turns out that inside was a story created dimension. What made it special however, was that said world was designed around stuff for foals and thus the three had entered that adventure as foals themselves. While it had been a lot of fun to outwit foes and play around, Starlight would have never expected that helping to end the game would grant her the “gift” of being a foal for the following next week.

Unfortunately she could do nothing to change this gift she was granted. According to Twilight she was stuck in this chubby and needy form until the magic wore off at which point she return to her adult self. She could already feel the foal like thoughts and instincts kicking in, the pacifier in her mouth was already slowly bobbing in and out without her thinking about it. Not that she’d regress to a drooling, mindless pile of mush or anything as extreme as that. Regardless, it was still very embarrassing.

Spike adjusted his grip a little while carrying Starlight out into the hallway. Moondancer followed behind on his left while Twilight lead the way to the room she had set up for their sleepover. Thankfully, the princess had helped foalsit the Cake Twins just last week with Pinkie, and thus had a small diaper bag full of the needed supplies. She knew she have to buy more, but that task would have to wait till tomorrow. Spike patted Starlight’s head. “Aww, are you sure she’s going to be safe sleeping in a bed?” He asked, once more adjusting his grasp to make sure he didn’t drop her. The foal suspected that her gift was causing some sort of magic to affected anyone near her, causing them to treat her like her current age, even if they knew the real her.

“Oh, I’m sure she won’t roll out of bed. But just in case.” Twilight smiled as her horn glowed, materializing safety rails around one of the beds. She turned around and scooped Starlight out of Spike’s arms, giving the little filly a nuzzle. “Okay, time for your beddy bye little foal,” she cooed, laying her down on the mattress.

Starlight wiggled about with a whine. “Nu-uh.” She didn’t care how she looked, she just felt fussy. However, her fit soon ended as her limbs gave out and she slumped. A warm blanket was pulled over her, the bed looking huge from her perspective. As a cozy embrace hugged the filly, she felt the sudden fatigue overtake her. As Twilight’s soft voice sang out a soft lulaby, Starlight suckled her pacifer, her eyes closing fully. It didn’t take long for the foal to doze off peacefully with a smile behind the binky.

The next morning was greeted with the rather unwelcome smell of a used diaper. Starlight kicked about, staring upwards as Twilight smiled down. “Mmm, get it off!” She whined, suckling upon her pacifier, and surprised that it calmed her down. Although she was still left in a bit of a bad mood to start her day, due to her unintentional soiling.

Twilight cooed at her motherly, holding her up by the forelegs as her body dangled. “Ah good morning, Starlight. Did you sleep well?”

Starlight cheeks flushed again as she was set upon the changing mat Spike had rolled out upon the large bed. “Y-yes, like a foal,” she replied, rolling her eyes when Spike chuckled at the comment. Twilight went about changing her diaper, the process was pretty much the same. The princess was oddly used to it thanks to that book adventure. It still felt a little awkward with Twilight doing it though, even if she was Starlight’s teacher. But the feeling was rather soothing. Twilight’s gentle touch and care, and her soft smile were just so motherly in feeling. She was almost a natural, or it could just be that lingering magic. In any case, it took no time at all for the fresh, white diaper to be taped up around Starlight’s bottom.

Twilight and Moondancer dawwed and nuzzled the foal from both sides. Starlight squeaked and blushed. “S-stop it!” She whined, being set down on the floor. Before she could ask what they were doing, Twilight had positioned herself by the bedroom door next to Spike.

“Come to Twily,” she babied, holding out her hooves.

Starlight could easily see Spike holding back a snicker as she began to waddle towards her teacher. When she was about halfway there, her hooves slipped on the crystal floor sending her flopping into her belly. A bright crimson radiated from Starlight’s face, as Moondancer patted her diaper bottom, causing the filly to try and cover it with her stubby tail. “It’s not funny!” She protested and stuck her tongue out at her freind. Twilight scooped her up in her magic and soon sat her upon her back. The unicorn shifted her hooves, kneading the soft fur before laying down. The filly simply let the adults carry her to the kitchen, grumbling all the way.

Out of all the embarrassing things that Starlight had to endure, the bib was the most demeaning. Around her neck was a pink coloured bib with purple frilly trim, and the words ‘Mommy’s Best Foal’ written on it. It went without saying that all the attention was both touching and demeaning, even if she was pretty weak. Twilight was letting Spike feed her and thank Celestia it was just oatmeal.

“Open wide, Starlight,” Spike cooed, flying the yellow coloured spoon towards her mouth. “Choo choo.”

Starlight tried not to laugh but ended up giggling a bit at the silly game as she nomed on the spoonful. “Mmm, I love peach,” She commented, eating another spoonful as she was fed. But after about five spoons or so she frowned. “Can’t I feed myself, please?” She whined.

Spike hesitated for a second, glancing over at Twilight who simply nodded in approval. “Alright, here you go. Be careful now, Starlight,” he babied.

Starlight just rolled her eyes as she held the spoon in her tiny pudgy hoof. She groaned internally, as the spoon wobbled in her grasp, even as she spooned some oatmeal onto it. “Gah, why is this so hard?!” She thought. With as much concentration as she could manage, the tiny unicorn brought the spoon to her mouth, and was rewarded as it got in just fine. She beamed, feeling overjoyed at the simple task! “I did it!” She cheered, the spoon falling out of her mouth as she had been too focused on clapping. She was so overjoyed in fact, that her hoof smacked against the bowl, sending it flying by mere accident into Spike face. As the oatmeal dribbled down the annoyed dragon’s scales, the filly broke out into a squealing laugh, kicking her hooves. She had no idea why but the moment was so funny that it was taking over any sense of logic she had. “Haha, sorry, Spike,” She laughed, apologizing as Spike cleaned himself off, groaning.

“Still no where near as bad as Flurry Heart from what I remember,” Twilight said with a snicker. “Come on, Spike. You can’t stay mad at something that cute.”

Starlight, after calming down from her laughing fit, blushed. “Uh, hehe, oops.” Then she looked at Moondancer, who was happily enjoying her own oatmeal. “Are you staying in Ponyville long, Moondancer?” She asked.

Moondancer looked up with a smile. “Oh, just til one or so. Why, you want to go the park and play? I bet you’d love it, little foal,” She baby talked, causing an even more adorable blush to form on the tiny unicorn cheeks.

Twilight nodded in agreement. “That’s a wonderful idea, Moondancer! Oh, if only we had something cute to dress her in.”

Spike commented while wiping of Starlight face. “We could always stop by Rarity’s. I’m sure she has something.”

“Spiiiike!” Starlight squeaked, “not helping.”

The dragon giggled, moving to get a fresh bowl of oatmeal for the foal. Starlight just crossed her hooves groaning at the thought of being Rarity’s helpless dress up doll.

Starlight’s guess hadn’t been too far off it seemed, as Rarity cooed at her as she sat, facing the large body mirrors while wearing a light purple coloured dress. The bottom kept half her diaper exposed no matter how hard she tried to conceal it. Rarity smiled while watching her try. “Now now, Starlight, it’s so your mommy can see if you had any accidents.” She cooed.

“T-Twlight not my mom!” Starlight lisped, wiping some drool off her chin.

“She might as well be for now,” Rarity countered, as Twilight laugh a little at the moment. The seamstress patted the diaper again. “Do you like your dress little star?” She asked. After a short nod from the foal, Rarity took it off and slipped on a yellow sundress with a matching bonnet tied around her head.

Starlight stood on her hooves and swirled a little as she looked it over. It really did look cute with her padding poking out, as much as she wished it could be concealed. “This one nice too,” she replied, watching as Rarity took the pacifier from around her neck and set it into her mouth with care. She suckled for a bit without protest. The sensation just felt normal.

Twilight pick her up and nuzzled nose to nose. “This one’s perfect, thanks Rarity!” Twilight cooed, setting Starlight on her back. The princess happily turned and strolled out of the shop taking in the smell of fresh flower beds. Spike followed suit slumping the diaper bag over his shoulder seeming to enjoy assisting as always. “What would my little pupil like to do?” she asked.

Moments later, the foal looked to her side spotting Moondancer near an ice cream cart, and was licking a maple nut cone. “Oh, ice cream!” Starlight squealed rather childishly. “Pleasee!” She begged, hearing a giggle from Spike as she did so.

“Such a polite little filly too,” Twilight teased, ruffling the filly’s mane before nodding. She trotted down the street and up to the cart, the magical metal container keeping its savory contents cold.

The brown coated stallion with alternating swirled locks of white and pink, and dark blue eyes, smiled at them, getting his scooper ready. “What can I get you today?” He asked.

Twilight lowered Starlight down to the glass case, so she could properly look at all the flavors. The filly scanned the row of buckets, before locking her eyes upon the mint chocolate chunk. Starlight tapped her hoof on the cold glass, smiling. “Dat one!” She bounced a little before stopping herself and blushing. “Stop it, you’re embarrassing yourself!” She mentally scolded herself, as she looked up while the stallion got a single scoop of the flavor into the cone. Twilight floated her back up.

“Does Starlight need me to hold her cone?” Twilight mothered causing another smile on Starlight muzzle.

“I-I’m good,” Starlight insisted. She held the cone with both hooves carefully licking as her friends smiled at her. She relaxed some more, thinking things over as they made their way toward the train station. Time flies when you’re having fun.

The Friendship Express rolled into the station with a soft hiss as the brakes were applied. Starlight gave a happy smile towards Moondancer, hugging her neck. “I’m glad to have made a new friend.” She beamed up at the glasses wearing unicorn. She honestly couldn’t wait to meet her again sometime.

“Yeah, it was great to meet you too. Hopefully next time we won’t be turned to foals,” Moondancer teased, ruffling the little foal’s mane. “You look adorable as a foal, yes you do.” She pinched Starlight’s cheek, causing a slight squeak.

“Mmm, so I hear,” Starlight mumbled, while being set back on Twilight’s back. She waved goodbye, as Moondancer got on the train, giving a wave back as the door shut behind her. The filly shifted a little, as the two watched the train leave. “What next?” She asked, getting comfy on Twilight’s back.

Twilight nuzzled her foal before making her way back toward her castle. “Oh, I think my foal needs a nap,” She mothered again, hearing a yawn right on cue. She hummed joyfully as she took her little filly home.

The day’s events only helped to influence Starlight’s dreams as the thought of her mother was fresh in her mind. Despite her questionable past, her mother had always been supportive in her younger years, at least before school started. Those happy memories bubbled to the surface, giving her a sort of peace.

The birds were singing outside as her mom smiled down at her, towering over the crib. “Aww, who’s my cute little star? You are, yes you are,” She scooped up Starlight in her hooves, nuzzling. The filly tried to tell her mother she loved her, only to babble and gurgle like any foal would. She mom didn’t mind though as she put her tiny hooves to her mommy’s nose and nuzzled. “Aw. Come on, let’s get you fed.” Her mother cooed.

Like any dream, time passed without flow, as Starlight was now in the highchair nomming the spoonful of mush with quite the mess on her face. “Mm..mmm..mama.” She managed to gurgle out causing her parents to aww and praise her. The filly clapped, not noting her horn glowing as it sent the bowl into the air and made it splatter onto her head. After the short surprise, she broke into laughter kicking about with gleeful bliss.

Meanwhile, Spike had come into the bedroom to check up on Starlight about an hour through her nap. He watched the light kicks and mumbles Starlight was making. Needless to say, she looked happy. And more joy was bound to come over the next few days for sure.

Well here we go agian, hopefull this story won’t take months to get finished :rainbowwild:

A friendly Visit

Starlight awoke from her afternoon nap with a yawn rubbing her eyes. The always unwelcome feeling of a used diaper greeted her causing her to shiver and whine. Twilight, as usual, was quick to trot in and comfort her. She clung to the coat as she moved to the mat set up. Needless to say, she didn't exactly hold still during the cleaning process despite the several changes she had gone through in only these two days. Once done she grabbed her plush beat and sighed

Twilight patted the fresh pink diaper which almost blended in with Starlight own fur. “There you go, all nice and dry,” she mothered, before setting the foal upon her back and took her along to the main study before setting her down on the soft playmat.

While Twilight went to sit down at a nearby table to look over her latest book, Starlight observed the toys before her. The inner foal was just wanting to play with anything that looked colourful while her adult side was just keeping her from putting anything in her mouth. After a moment she chose to take the crayons near by and draw some images. She started with a stick figure of her and Twilight passing a ball between each other. The foal idly kicked her legs while she drew humming to herself. The fun activity reminded her of when she and Sunburst would do crafts together, although looking back she could definitely tell she wasn’t much an artist but her dad had always given the supportive ‘that very nice’ and the usual parental praise. Starlight chuckled a bit realizing this week long foalhood was giving her some perspective.

“Everything okay, Starlight?” Twilight asked, leaning down to look at her.

Starlight blinked and twitched a little. “Huh, oh yeah just got lost in thought is all,” Starlight lisped, moving her crayon to make Twilight’s mane.

Twilight raised an eyebrow and kept smiling. “Oh, what about Starlight?”

“Just about Sunburst and how we used to play,” the filly stated, drawing a small tree next to herself adding a tire swing to it.

“Aww, do you want me to set up a playdate?” The princess teased playfully, reaching out with her wing and tickling the foal’s side.

Starlight immediately eeped, laughing at the feathery assault. Her eyes then went wide. “No, I don’t want him to see me like this,” her cheeks redden again imagine him seeing her small chubby form and cooing at her like everyone else had been for the past few days. Something about a close friend seeing her like this just seemed so embarrassing even if Twilight’s friends had seen her already.

Her caretaker just laughed some. “Oh don’t be a silly little star, you been seen by a bunch of ponies by now.” Twilight happily reached down and scooped up her charge nuzzling motherly. Just as Twilight was about to speak again, Spike was heard skittering down the hall.

“I’ll get it,” Spike shouted, clearly having heard someone at the front door while Twilight had been distracted.

Twilight carried Starlight on her back as they move down the hall to check out who had come to visit. They didn’t have to wait long as Starlight heard the crisp projected voice of the guest. “Hello Spike, Trixie is here to chat with Starlight while she’s in town.”

Starlight eeped in sudden panic. She wasn’t sure why but the thought of Trixie seeing her like this made her worry she laugh at her. As illogical as it was she still reacted her horn having an urge of magic which caused her to teleport away. It had been impulse really she hadn’t meant to but in her current tiny form, her magic was unstable when emotions came to be a factor. Turns out that she had reappeared in her bedroom of all places. The startled filly quickly waddled under her bed to hide. The sounds of hooves were heard running by as Twilight was no doubt in a panic to find her but the foal did not budge despite not wanting to upset her ‘mommy’ more. The two sides of her mind kept silently conflicting as she kept an ear out shaking lightly. Several moments passed before her door was opened.

“Starlight!” Twilight called out, glancing around the room. “This is no time for hide and seek.”

Starlight could see Trixie behind the princess looking confused. “If she isn’t home Trixie can come back later.” Trixie paused realizing what Twilight had just uttered. ‘Wait, hide and seek? Isn’t that for foals?”

Twilight spun on her hooves facing back at the unicorn. “That because she is a foal.” The princess entered the room peeking under the desk.

“Foal? Wait, you actually pulled off the age spell?”

“What, no I didn’t do it, was some book it’s a long story,” Twilight remarked getting closer to the bed. Starlight attempted to move away from sight only to stick her tail out from the edge of the bed.

Trixie keen eyes spotted the stubby tail encompassing her magic around. Starlight yelps in a start as she dragged out slowly. “Gotcha.” The magician declared only for her horn to be booped by Twilight’s outstretched hoof dispelling the light telekinesis.

“Trixie no, that is no way to grab a foal,” Twilight mothered soon picking up the stunned filly. She pressed Starlight to her chest “Shhhh, there there, don’t be scared it’s just Trixie.”

Trixie was quite surprised to see this side of Twilight considering she never seen such maternal ponies since she been hired to do an act at one of Manehatton’s daycares. After recovering from the horn flick she stared at Starlight who was clinging to Twilight chest for comfort. “So some enchanted book turned her into a foal? Didn’t think she was that careless.”

Starlight whined, “It wasn’t my fault.” She looked away embarrassed. Don’t call me cute, don’t call me cute-

“She looks so adorable with such chubby cheeks,” Trixie complemented.

Drat, here it comes. Starlight clung to her caretaker more already hearing the tone change in her friend's voice.

“Can I hold her, please? I didn’t mean to scare the filly.” Trixie held out her hooves. The protective mother only hesitated for a few seconds before passing the foal over to the unicorn. The mare dawwed a little and give a little tickle to Starlight’s tummy.

The embarrassment quickly faded as Starlight giggles pushing helplessly on the massive hoof. ‘Heheh, no me ticklish.” Her speech slipped for a moment as Trixie made faces at her which only caused a few more burst of laughter out of the easily amused mindset.

Spike watched with an amused smirk. “Wow Trixie, you’re a natural.”

Trixie scoffed, “Oh playing with foals is easy, Trixie had to take few foal sitting jobs to make ends meet once. Thankful the little ones I was foalsitting were out of diapers.” She booped Starlight’s nose. “Boop got your nose.” She pulled her hoof back watching the foal reach out for her supposed stolen nose.

Starlight wiggle and reach out for the hoof thinking her nose was taken “Nu gimmie back.” She didn’t stop herself from slipping into such playful behaviour finding it to be quite fun.

Trixie giggles as well moving her hoof away. “Uh, uh what the magic word?” she asked, grinning ear to ear.

“Please!” Starlight hit her friends with the power of her foalish big puppy dog eyes. She giggled when Trixie smiled back at her and rubbed her hoof on the foal’s nose. ‘Yay!” the filly cheered.

Spike and Twilight couldn’t stop smiling at the innocent moment letting Trixie tickle the filly again. After a minute, the group headed to one of the study Starlight set down on the soft playmat once more. Trixie sat down nearby and passing a ball to the filly. “So, how being a foal feel?”

Starlight held the ball in her tiny hooves taking a moment to look at Twilight. “Uh, small and constantly called adorable. I guess it is nice to just play and relax without a care. Could go without making stinks so much.”

Trixie snickered covering her mouth in a vain attempt to hide her smile. ‘Oh I bet that is so gross, but you must tell Trixie how you got turned into such an adorable little star,” she teased, ruffling the short mane again.

Gah, what is up with this spell and lack of personal space! Starlight shook her head for a moment. “Like Twilight said, it was a magic book.” She told Trixie the tale of her adventure especially the part where Trixie had been up on stage dancing around in padding too.

Trixie blushed. “What? I never dressed up like that,” she paused leaning down. ‘Did I at least put on a good show?”

“Yeah, and adorably too,” Twilight interjected, amused when she saw Trixie blushing. The reaction caused Starlight to laugh in delight and kick her legs in the air and rolling into her back.

“Laugh at Trixie, will you? Well here comes the Great and Powerful Tickle monster.” Swooping down like an eagle, Trixie began to raspberry her friend's tummy. “Pffff!” The filly squealed worming around happily as she tickled. “Haha, take this.” She did another before pulling back giving the filly’s nose a light boop.

Twilight awed and soon picked up her foal. “Uh oh, you need a diapee change,” she cooed, seeing Starlight blushed having just not noticed the sogginess. She nuzzled once more and laid her foal on the changing mat once more going about the change. “I”m going to take you to Canterlot tomorrow and show you off to my parents. I’m sure Celestia will find you adorable.”

Starlight resumed blushing at the news of even more embarrassing moments to come. On the other hoof, she got to have more fun too. The filly finds herself relaxing as her fresh pink diaper was taped snugly into place. Her temporary mother pulled her into a cuddle the warmth washing over her. The other two watched as she hugged back with her tiny hooves pressing into the chest and listening to the heart beat.

While Twilight held her foal close she could pick up the unmistakable sound of a low rumble and smiled. “Aww, I think somepony is hungry.“ Without another word, the group moved along to the kitchen and the foal sat into her highchair. The princess once more smiled at Trixie float the baby food out of the cupboard. “Do you want to feed her Trixie, she well behaved.”

Trixie could already see Starlight make a face at the particular flavor Twilight had chosen shuffling it away from her with a light nudge of her hoof. Her action was only counter by Twilight nudging it back without any reaction. “Can’t hurt to help the princess, although I don’t think she likes the flavor.” Trixie pointed to Starlight sticking her tongue out.

“Oh, she just being fussy,” Twilight dismissed, tying a large pink bib to Starlight neck.

“Bleh no want cabbage,” Starlight whined, as Trixie came over to the highchair and picks up the spoon.

“Well, if that what Twilight wants you to eat then you will eat it,” Trixie replied, spooning up the green mush. It did smell a bit odd but harmless regardless. “Come on now, eat up.” The spoon boops on the foal’s lips. Starlight kept being fussy shaking her head as the spoon smeared the bland veggie mash on her lips. “Oh, do you want the tickle monster to get you?” Trixie teased.

“Eep no not again,” Starlight whined, covering her tummy with her hooves only for the spoon to go swapping into her mouth. She whined swallowing on reflex sticking her tongue out. “Uck.” she kept being fussing as Trixie spooned the meal into her mouth the magician having to use funny faces at one point to have the foal open up. After a few more spoons, Starlight gave in and just ate her meal despite the not preferred flavor. Thankfully, at the end of all strain on her taste buds, came a nice bottle of chocolate milk. The filly squealed and latch on guzzling it down with glee as the icky taste was washed away.

After dinner, Trixie had set up a puppet show using plushies and a few props. The teddy bear glowed in Trixie magic as the puppeteer moved her props around. Spike was helping too as he moved the pony figure around. “You’ll never have our honey,” Spike said in a silly voice, dancing the toy around.

“I will little pony, for I am the bear spirit oooh.” Trixie sprinkled glitter on the pony figure using her magic to make it extra sparkly. Starlight cooed and seemed easily amused by it looking simply adorable.

“No, not that bear curse!” Spike shook the pony doll around pushing it down and swapping it for a blue teddy. “Change me back meany.” Spike barely kept a straight face at the silliness.

“Yeah meany,” Starlight injected, clapping childishly. This is pretty goofy.

Trixie giggles and moves the bear again. “I will only change you back once you get my honey,” she set a jar next to Spike.

“But don’t bears eat fish?” Spike asked moving his doll to pick up a flat cardboard fish.

Trixie gasped. ‘Oh, fish!” The teddy noms on it flopping along the ground causing more laughs from Starlight. The play kept going for another ten minutes being full of random events and silly voices. Soon the evil magical bear was defeated as a yawn escaped Starlight mouth despite trying to hide it.

“Well looks like it’s little Starlight’s bedtime,” Twilight sang, picking up her filly and patting her back as Trixie helped to clean up the toys.

Starlight rubbed her eyes as they droop slightly. “B-but I wanna play more,” she yawned.

Trixie smiled turning to face her beaming ear to ear. “This evening was quite fun I felt like I was a child again. Maybe Twilight can change you into a foal again sometimes so we can entertain you,” she teased.

The foal found herself leaning into Twilight’s chest as she taken along back to the bedroom. “Tomorrow going to be fun I just know it,” Twilight said, while getting the foal changed and into a pair of soft blue pajamas. She lowered Starlight onto the bed watching Starlight hug her new teddy bear.

Starlight looked up at Twilight for a moment with a smile. “Thanks for watching out for me,” she said, before laying her head back down and closing her eyes. Within a minute the foal had dozed on into a peaceful slumber. The caretaker one last check that the filly was comfortable before heading to the door. She was going to miss being a mother after this week was over, but what a learning experience it been so far.

Playtime in Canterlot

The towering buildings of Canterlot came into view as the train steamed its way out of the tunnel. Starlight stood on her hind legs, just barely able to keep her head high enough to watch the sight. With her nose pressed on the glass, the sight, to say the least, was adorable. Twilight reached down and ruffled the foal’s mane. “Enjoying the view, Starlight?” She asked, smiling wide.

Starlight wasn’t sure why, but she felt a sense of wonderment from watching everything from her new stature. “Uh huh, everything is just so big,” She lisped, letting out a few coos as she watched the snow fall on the tops of the tall cliffs. Soon the smooth marble towers came into view, shining in the late morning sun as the train pulled into the station. The foal turned from the window, getting a prompt nuzzle from Twilight, before being set into the stroller. She kicked her legs and cheered when Spike got out her teddy bear. With grabby hooves, she snatched it out of the dragon’s hands and held it close. The filly just loved her present feeling comfort and safety when she had it. “Thank you, Spike.” She cooed.

Spike patted Starlight’s padding and smiled back. “No problem, Starlight.” With a quick motion of his claw, the dragon ruffled the filly’s mane.

Twilight continued to smile, relaxing as she pushed the stroller along with her magic. Birds sang in the trees as they passed, moving down the road to her parents’ house. “Oh I bet my parents will love you.”

“I got a perfect track record.” Starlight mumbled, hugging her teddy while leaning back to enjoy the ride.

Spike chuckled. “Oh, you know your mom is going to pull out the baby photos again. Right, Twilight?”

Twilight blushed. “Yeah, maybe we’ll see you being bathed by me. Mom kept a lot of your baby pictures too.” She retorted, patting Spike’s head as they neared the house.

Starlight giggled again, squeezing her teddy and grinning, as Twilight Velvet opened the door. “Oh, Twilight, I didn’t know you were coming over.” She said in a surprised tone.

“I thought it’d be a nice surprise, hope you’re not busy.” Twilight smiled, wheeling the stroller inside.

“No, no, never too busy for my own kids,” Velvet commented, looking down at Starlight. “Aww, hello to you too,” She mothered, ruffling Starlight’s mane. “Wasn’t she bigger though? I seem to remember her being a full grown mare last time I saw her.”

“Long story but it’s only temporary,” Twilight explained, as she floated Starlight out of the stroller, checking her foal in front in front her mother.

Starlight eeped and whined. “Twilight!” She blushed, seeing Velvet watching and awwing some more.

“Oh, just checking for poopies. Don’t need you getting an ouchie diapee rash.” Twilight sing-sang, patting the diaper. It was only a little soggy, but the fact still made Starlight blush again. The lack of control was really inconvenient (for the most part anyways) always interrupting things. Plus there was the constant embarrassment of needing to be checked and depending on someone else. She was glad when the change was over a minute later.

“Oh, she’s just so fussy, can I feed her?” Velvet asked, Spike being quick to pull one of the bottles out of the side pockets of the diaper bag. Spike gave the bottle over to Velvet, who with practiced skill, took Starlight into her hooves and angled the bottle to Starlight’s lips. The filly cooed and began to drink with ease, her forehooves holding the bottle. “Aww, good foal, drink your baba.” Velvet cooed, slowly cradling the little one as old instincts took root once more.

Twilight watched in awe, and decided to pull Spike into a warm embrace as she observed the feeding. The drake happily leaned into the hug with a smile. “Oh, it’s been a great week, Mom. Starlight is so well behaved for a foal.”

“That’s great to hear,” Velvet commented, as Night Light walked over to coo at the foal as well. “Hope she’s not as active as Flurry Heart.”

“Starlight is absolutely tame in comparison to Flurry Heart,” Spike commented, still pressing into Twilight. Despite his age he was quite the cuddler too.

Starlight, meanwhile, let out a burp over Velvet’s shoulder, blushing a tad. “Excuse me.” She said, wrapping her hooves around the mare’s neck and pressing into her. She relaxed, letting out a sigh. Velvet, in turn, massaged the foal’s back while humming to her. Starlight smiled wider, slumping into the cuddling. Twilight and Spike followed Velvet to the living room as she sat down and keeps up the back rub. “Well, it’s good to know she having so much fun.”

The foal nodded. “Uh huh, it has been fun.” She didn’t want to let go, feeling really soothed by the mother’s warmth just like with Twilight. Starlight wanted as much of this as possible while it lasted.

Twilight hugged her dad as he came in. Night Light smiled. “Oh, it’s good to see you again. Been behaving yourself?” He asked his daughter, soon taking a glance at Starlight. “Oh, what a cute little filly, brings back memories of Twilight as a little one.”

Starlight tried her best to hide behind Velvet’s hooves, shyfully waving a hoof in his direction. “H-hello,” She lisped, once again pressing her face into the fluffy coat while feeling meek.

“Oh, is she shy?” Night Light asked, sitting next to his wife. Velvet switched Starlight to his lap, the filly shifting about. “Aww, little Starlight is just so cute. I could just eat her up.”

Starlight, in return, eeped and kicked her legs while smiling. “Nu, don’t eat me!” She squeaked. But Night Light tickled her tummy, causing delightful laughter to erupt from the foal’s mouth. “Twily, save me!” She squealed, reaching out for her friend!

Twilight played along, scooping the little one out of her dad’s clutches and into a hug. “Oh, don’t worry, I’ll save you,” Seeing the filly smile more, the princess ruffled her mane and gave a nuzzle in return. “Oh, I can’t wait to show you to Celestia.” She looked over towards Spike. “Did you remember to bring that magic book with us, Spike?” She asked him.

Spike gave a thumbs up, patting his backpack. “Sure did, wonder what they’ll say about it.”

Starlight’s cheeks turned red with embarrassment at the thought of Celestia cooing and dawwing at her, much like everyone else had this whole week. She was calmed down some by the pacifier that was set into her mouth, it bobbing slowly in a rhythm. The little foal leaned onto Twilight’s chest, getting comfy, while the adults talked on for a while.

Soon, Velvet turned her attention to the foal and smiled. “So, Starlight, what did you want to play?” She asked, booping Starlight’s nose and causing the little one to cover it and clap. “Maybe hide and seek?”

Starlight smiled, bouncing some and feeling a burst of energy, as something came to mind she hadn’t done since she was a toddler. “Sprinkler!”

Velvet blinked a few times, before glancing over at Night Light. “Oh, I think we can set up the little sprinkler for you to play in. I think we have a slip and slide too.”

"That sounds fun, i’m sure she love it. But won’t that take a few minutes to set up?” Twilight asked, while nuzzling Starlight again.

“It’s no problem at all, Twilight,” Velvet commented. “Besides, Spike will enjoy it too, he’s small enough.”

“Hey, I’m big!” Spike protested, puffing out his chest to try and look manly. It only lasted for a second however as he nodded. “But yeah, waterslide sounds like fun. But won’t Starlight’s padding get all soaked? We don’t have swim diapers.”

“Don’t worry, Spike,” Twilight said in reassurance. “I’ll just use a spell I use on books when I go to the pool or the beach.”

“Or the tub.” Spike teased, causing Twilight to blush.

“That was only a few times!” Twilight protested, hearing Starlight giggle at her embarrassment. She then reached down and scooped Starlight into the air. While her parents were setting up the activity, the princess happily flew Starlight around the room using her magic, letting Starlight turn and steer herself around like one of Spike’s comic book heroes. Spike even added a small red cape to Starlight back to add the look. The two watched her fly about for a bit, but soon she landed on Twilight’s back as they made their way to the backyard.

The slip and slide was pink in color and shaped like a small castle drawbridge, with water flying out in the tiny holes along the runway. Twilight smiled. “Huh, it’s smaller than I remember.”

Starlight giggled. “Nuh uh, you were smaller,” She was helped to the soft grass, soon darting off to the start of the slide, water already sprinkling on her. Joy ran through her body as she backed up and ran as much as she could manage with her padding (thankfully protected with a spell) soon flopping onto her belly as she slid down the slick path, letting out squeals as she did so! When she came to a stop, she got up and giggled a little, upon seeing she came up short of the end. This did not deter her, however, as she happily went to try again. She stopped midway, observing Spike take a short running start and slide along a little too fast causing him to sip off the end of the slide and tumble to the grass, thankfully unharmed. “Spike is silly.” She laughed.

The fun continued on for some time. Both Spike and Starlight lost track of time as they slid and played in the water. By the time Twilight pick Starlight up to dry, the filly was well and truly ready for a nap, having spent her energy for now. Starlight let out a big yawn once she was all dry and warm, wrapped in a fresh onesie straight from the dryer. The radiating warmth of both her sleepwear, and Twilight’s gentle humming quickly sent her off to dreamland with a smile.

While Starlight slept, the thoughts of her mom teaching her the alphabet came to the forefront of her mind. Times sure were simpler back then it seemed. No wonder she was so accepting of this mini vacation. She was startled awake quite suddenly however, when a light bump shook the stroller she’d been set in! She rubbed her eyes, adjusting to the change in light, observing the grand entrance hall of Canterlot Castle and the ceiling that seemed to stretch upward forever.

Spike was the first to notice she was awake and smiled at her. “Oh, you’re awake. Feeling well rested?” He asked, checking her padding like any good caregiver.

Starlight smiled back in return, her hoof clinging to her plush teddy bear. Another yawn escaped her mouth. “Yeah, doing great. Do we have to see Celestia?” She pleaded, hopefully.

“Aww, don't be shy, Starlight. Celestia set an hour aside just for us. We don't want to disappoint her.” Twilight cooed, moving the stroller down the hallway and passing a few guards and maids. A few of the staff even waved at the foal, causing Starlight to hide behind her teddy in response.

Upon entering the study, the group noticed the nice plate of brownies and other small snacks set upon the oak table. Celestia smiled at them as she came up and gave a light hug to each of her guests. The princess was quick to pick up little Starlight and nuzzle her as well. “Oh she’s so cute, hello Starlight,” She spoke in a motherly tone. “Have you been a good little foal for Twilight?”

Starlight cheeks flare again as she nodded. “Uh huh, me good.”

“And who’s your little friend?” Celestia asked. “Does he have a name?”

“Um, I don’t think so. Does snuggle count?” Starlight replied in a sheepish tone. The solar princess awwed and set the foal on the couch of her study, letting Twilight sit too, while Spike stuffed a brownie into his mouth. Once the dragon was done wit his treat, he moved to his backpack, pulling out the adventure book that had started the whole mess. “Here it is, this is what’s responsible for Starlight’s current appearance.” He explained, and set it down before sitting himself off to Twilight’s left.

Twilight watched as Celestia opened the cover, looking it over before flipping a few pages and smiling while letting out a chuckle. “What did you find, Celestia?” Twilight asked with concern. “Is this book dangerous at all? There won’t be more random moments of being sucked into it, will there?”

Celestia’s smile grew as she looked up. “No, you and Starlight are perfectly safe. This book is one of many copies of a creation of an old student of mine.”

“Personal or the institution?” Spike inquired getting a cross look from Twilight for interrupting.

“Personal,” Celestia explained. “I was not as hooves on with her as I was with Twilight or even Sunset and Sunburst, but I did still get to see her talents bloom. Star Dreamer, I believe her name was. She was only my second student ever.”

Starlight blinked, staring down at her chubby body. “She made books that turn ponies into not potty trained foals?”

This got another laugh from Celestia. “Just that particular adventure, it seems. She always did have that mindset that one needs to experience things rather than just read them. A philosophy I practice all the time, though not to this extent of course,” She gave a knowing look in Twilight direction, and then continued. “I suspect the week-long foal reward was meant as a lesson of sorts,” She floated Starlight into her lap and tickled her with a wing. “I guess some filly need to learn to embrace their childish side a little more, and learn to slow down and just enjoy themselves.”

Starlight squealed at the tickles. “Hehe, what? Why would I need to do that?” She asked, while grasping onto the rattle that Celestia had picked out of the diaper bag.

“Well, I’m not sure why you were singled out amongst the group. Perhaps it was a mistake,” Celestia concluded. “But what I am sure about, is that you are enjoying being smothering in love and attention, no?” Celestia replied, watching the foal shake the rattle gently.

Spike watched Starlight having fun “So, that magic? Can it be triggered again?” He asked as Twilight giggled.

Celestia nodded. “I believe so. Why do you ask? Thinking of turning into a hatchling again, Spike?” She teased.

Spike blushed, puffing out his chest. “N-no, I’m a big boy. I was just asking.”

Starlight, meanwhile, shook her rattle. “Oh, but you were adorable in that gem print padding, Spike. Maybe you should try it sometime. You might like it,” She lisped. “I know I am.” The filly proceeded to giggle as Celestia decided to fly her around the room again just like Twilight had done earlier. Sure, she could fly by her own power when bigger, but this was something new. Plus being so light let her do loops in the air as if on a rollercoaster.

Spike just kept blushing. “Uh, I guess I’ll think about it.” He squeaked, getting a nuzzle from Twilight.

As Starlight was lowered into Twilight hooves, Celestia couldn't help but ask. “So, Starlight, anything else you and your mommy used to do when you were younger?”

Starlight tapped her chin, resisting the urge to suckle her hoof as she did so. “Ummm, I sort of remember wagon rides.” She confessed.

Celestia beamed upon hearing that, promptly standing up. “Oh, I know just the little wagon to use. Shall we?” Upon seeing Starlight clap happily as confirmation, the group headed out along the hallway, steadily making their way to the garden.

Starlight’s gaze never stopped darting around as she looked at every bright flower they passed, as she was wheeled along in a white wagon. The few trips to Canterlot she had made before had never been to many gardens. She’d always been focused on libraries (except for the one occasion of stalking Twilight around). This truly was the first time she’d seen such exquizite arrangements of flora. The few animals she did manage to spot kept their distance, the cuteness had not been an overstatement when Fluttershy had told her about her trip to these very gardens. The filly squealed and put her hooves up in delight. “Weee!” She cheered.

Both princess’ awwed at Starlight, as they took their time strolling through the garden. Celestia continued to watch Starlight's carefree gaze. “It’s times like these that make life worthwhile. Seeing the young enjoying the world.”

“Yeah, being a mother’s not so bad at times.” Twilight smiled, pushing the wagon along some more, moving just a bit faster to entertain the filly.

“Even diaper changes?” Celestia teased.

“Well, those are kind of gross.” Twilight admitted with a blush. The two hd a laugh over the thought, until fate had convenient timing. The semll of Starlight’s diaper caught Twilight nose almost instantly, as the foal whimpered.

“Speaking of changes,” Celestia commented, as she lifted the filly out of the wagon. “You wouldn't mind if I tried changing her, would you?”

“If you want to, sure.” Twilight commented, and rolled out the mat even as Starlight whined.

“Eeep, no!” Starlight covered her eyes. “I’ll never live this down!”

“This isn’t the first time I’ve had to change a diaper, silly,” Celestia mothered laying the foal upon the flora decorated mat. “Just last month I was helping promote a local daycare.”

“Oh, what happened?” Spike asked, handing the supplies out while making sure Starlight had her teddy to snuggle to keep calm.

“Well turns out it was one of the foal’s birthday, so the mother asked me to change her little darling and well...I got peed on.” Celestia admitted with a blush.

Spike and Starlight both snickered as Twilight scolded them. “Spike! Starlight! That’s not funny!”

“Oh no, no, Twilight, it’s okay,” Celestia giggled. “I mean, I got a laugh out of it too. That hasn’t happened since I was helping you change Spike’s diapers.”

Spike frowned, crossing his arms. “What up with everyone making baby jokes about me today? I’m not a baby.” He promptly got a light hug from Twilight.

“It all in good fun, Spike.” Twilight told him, as she placed the used diaper into a bag for disposal.

Starlight continued to giggle, snuggling her bear as she was changed. Once the new diaper was all taped up, the princess scooped her up once more and sat her back in the wagon. “Hehe, thank you.” The foal squeezes her teddy bear, still feeling embarrassed at having messed herself in public like that (even if the princesses and Spike were the only ones around to see it).

Starlight was wheeled around for a bit more time, staring at the various statues in the garden. But soon, Celestia’s time came to an end, as she looked at her pocket watch. “Oh, how time flies,” She commented. She promptly leaned down, gave Starlight a light hug, and then stood up. “It was nice spending time with you three.”

“Yeah, wasn’t so bad, aside from the whole diaper thing,” Starlight admitted, watching Celestia head back towards the castle with a skip in her step.

Once at the train station, Starlight looked up at Twilight. “So, um, what next?” She reluctantly asked.

“Oh, you’re going to LOVE tomorrow! We’re going to visit Cadence!” Twilight happily squealed.

Starlight meeped in realization. “That means Sunburst!” She blushed deep red at the thought of him of all ponies seeing her in this state.

Author's Note

Sorry it took so long.

on the plus side, i left things open in case I want to do a story with Spike being turned hatching in said book. who knows.

Crystal Empire

“And so the princess was saved, and the family lived happily ever after.” Twilight finished, closing the story book as the train neared the Crystal Empire. Starlight was happily leaning on Twilight's chest, enjoying the pacifier as it bobbed in her mouth, despite the nerves of the upcoming moment of being seen by her old friend. Twilight had been doing a pretty good job at keeping her distracted, giving Starlight little time to let any of those thoughts sink in much.

The two or so hour train ride had been filled with many short stories and Spike had been keeping her occupied with plushies.The little dragon seemed to be a natural at looking after foals. The filly soon moved to the window, standing on her hind legs to peek out at the falling snow. The sparkling towers of the empire soon came into view entrancing the little filly, despite the fact that she’d seen it before.

Twilight silently awwed at the sight, while at the same time putting away the toys she’d gotten out for the foal. It wasn’t long until the train pulled into the station, ponies wandering about as they rushed to either get on or off a train. Twilight effortlessly set Starlight into the stroller and wheeled her out onto the platform. Upon exiting the train however, they were met with another surprise.

“Twily!” Shining called, walking up to the group and giving the alicorn a hug.

“Hey, Shining, I didn't know you would be meeting us at the train station.” Twilight greeted, returning the hug.

“Well Cadance would have come too, but she got busy with Flurry, and paperwork,” Shining commented, leaning down and tickling Starlight. “Aww, she’s so cute.” Shining kept tickling, watching Starlight kick and squeal with delight.

“Was it more fan mail?” Spike asked with a smile, idly waving at any crystal ponies that looked his way.

“Yes, that and some paperwork Celestia has ‘shared’ with her.” Shining let out a chuckle, watching Starlight blush and hide behind her teddy bear.

“Well, I’m sure Starlight and Flurry Heart will have great fun playing together,” Twilight commented. “I’ve been having a blast myself.”

“That’s great, you seem to be a natural.” Shining smiled, leading the gang along the road to the castle.

As the group was led along, Starlight shifted and blushed again, remembering Sunburst. She lanced up at Shining, sputtering. “Will Sunburst be there?” Once more squeezing her bear for comfort.

“He’s in the castle library last time I checked,” Shining replied, as the guards opened the main doors for them. “I”m sure he’ll check up on Flurry Heart as well, she’s a troublemaker.” He didn’t notice the eep that escaped the little filly’s mouth.

Starlight was soon distracted again, as Spike shook a rattle in front of her. For whatever reason the sounds always entranced her (it might have been the fact that she was a foal). The foal snatched the rattle with her spare hoof and giggled, shaking it lightly. She played with the toy in such simple delight, that she didn’t notice that they had wheeled her into the playroom. The walls were decorated with various scribble drawings and little hoof paintings.

Flurry looked up from her blocks and squealed upon seeing a new playmate, and her Auntie Twily. The happy foal fluttered over to Twilight and hugged her, babbling happily.

“Aww, hey, Flurry Heart,” Twilight greeted. “We brought you a playmate.” She said in a sing-song voice, patting the foal’s cute blue diaper. The filly giggled again and cooed, looking down at Starlight with curiosity.

Starlight waved up from the stroller. “Hi there.” She sheepishly greeted.

Spike helped her out of the stroller and sat her on the floor, watching Flurry flutter over. Starlight let out a giggle at the tiny alicorn booped her nose. “Hehe.” She laughed, covering her nose for a second, before returning the gesture. It didn’t take long before the two foals were in a playful booping war, breaking into giggle fits as they did so. Starlight soon made a retreat, running toward the plushies across the room. Flurry gave chase, babbling and trying to grab Starlight’s stubby tail. The adults watched, grinning at the adorable sight.

Then Starlight grabbed one of the plush elephants and tossed it at Flurry’s face. Flurry stood there as it impacted, shaking her head, before laughing and floating up all the plushies. Starlight eeped and waddle away, dodging tossed plushies as best she could. She only got so far though, before she ran into the large teddy bear. Flurry made a dramatic downward motion with her hooves, before the large plush fell on top of Starlight. “Eeep!” It wasn’t actually all that heavy, but Starlight decided to play along, wiggling about as if she was trapped. “Help me!”

Flurry clapped and flutter on top of the teddy bear sitting on top of it, and Starlight. She babbled, watching the other foal wiggle and pout. Shining giggled. “Come on, Flurry, play nice.” He cooed in a fatherly tone.

Flurry obliged. She slid off the teddy and floated it off Starlight, giving the foal a boop on the nose again, before moving away. Starlight resumed the chase, darting around the room and even running under Shining and Twilight’s legs.

Spike watched for a moment, before joining in, making grr sounds as he chased the two around the room. Knowing the two foals were in good claws, Twilight and Shining left the room to chat a bit. Spike didn’t mind that at all, the drake kept up his little game, only pausing to get Flurry’s diaper changed when she’d wet it. Once he finished getting the filly all clean, a familiar stallion walked into the room, spotting Starlight almost instantly.

“Starlight?” The stallion asked, taking his glasses off in order to blink and rub his eyes. No, he wasn’t seeing things. He watched as said foal waddled quickly behind a plushie, hoping to hide. The idle magic was already causing Sunburst to smile. “Aww, come on out, little Starlight.”

“I-I no here.” Starlight squeaked, still staying poorly hidden behind her plush bear, her diaper sticking out prominently. Her cheeks continued to radiate as Sunburst walked over and scooped her up. She let out a squeak as he petted her mane.

“Oh, she’s so cute!” Sunburst cooed, patting Starlight on the forehead. “Why are you so small, Starlight? Some spell I bet, or was it some artifact?”

“A little of both, actually,” Spike explained, before Starlight could get a word in. “Some magic adventure book to be precise.”

“Wow, a enchanted book that turns you into a foal? That sounds like some powerful magic,” Sunburst commented, just before he felt Starlight lighty swat his muzzle to get his attention, blinking as he looked down at her. “Uh, sorry, Starlight. I got carried away. But you’re so adorable.”

“Well, no need to talk about me like this when I’m right here.” She let out a humpf, looking away while pouting adorably.

“So are you going to tell me how you ended up like this?” Sunburst gingerly asked. “Or do I have to get out the tickle monster like I do for Flurry Heart.?”

Oddly, both Starlight and Flurry squeaked at the same time, the latter clinging to Spike. As Sunburst’s hoof touched Starlight’s tummy, she meeped. “No, no, I’ll tell!” She got comfy in his hooves as she told him the journey through the foalish land, that was inside said adventure book. She blushed as she finished. “And apparently, when I helped win da game, I got rewarded with a week as a foal. This my last day.”

“Fascinating,” Sunburst commented, adjusting his glasses. “I really should have a look at that book later. It would be great for my collection, or maybe Twilight could help find a copy for me,” He stared at the filly once more. “Aww, you even have your pig tails like you had when we were kids, that’s adorable.”

“So I’ve been told.” Starlight rolled her eyes as Sunburst set her down.

“How does being a foal again feel anyway?” Sunburst asked, changing the subject. “You look awfully chubby.”

“Mmm, I’m not chubby,” Starlight whined, hearing Spike snicker. “It rather nice at times, and Twilight a great mother too. Could go without diaper changes though.”

“Oh don’t be silly, you’re not potty trained yet,” Sunburst teased, ruffling her mane once more. “We both know you weren’t potty trained til you were almost three and a half years old.”

“Well.. I’ll be a big filly again tomorrow, so there.” Starlight stuck her tongue out, unable to hold back a giggle as she bounced on her diaper bottom.

“Can I at least get to see the photos?” Sunburst all but pleaded. “I’m sure Twilight took a few.”

“M-maybe.” Starlight blushed, squeezing her teddy bear close. Flurry just clapped her hooves at the silliness, and once more gave Starlight’s nose a light boop, babbling contently.

Sunburst scooped the two up in his magic, swiftly moving to the sofa nearby, as he sat the two between his legs. “Well, how about I tell you two a nice story?”

“Yay, story!’ Starlight cheered, before blushing and covering her mouth. These foalish outbursts were getting to be really embarrassing.

“I think she’s gotten a little too used to being a foal.” Spike giggled, while Sunburst patted the seat next to him.

“Come on, Spike, I’ll read to you too if you want.” Sunburst offered.

Spike opened his mouth to complain but soon closed it and sighed, hopping up and getting comfy. He blushed a little as Starlight stuck her tongue out at him.

Starlight herself leaned on the warm chest of Sunburst and sighed, listening to the story and Sunburst’s sweet voice. She felt sheepish at having been worried of what Sunburst would think of her. That magical aura sure helped things go easier. Plus he was a pretty good foalsitter. Well maybe not as good as Twilight, but still close. He was a good friend, she shouldn’t have worried so much. It wasn’t like he was going to tease her or pick on her.

As Sunburst read to the two foals, they began to get sleepy. Even Spike rubbed his eyes a bit, as the stallion used silly voices. He felt the two foals pressing against him, yawning more as their pacifiers bobbed up and down in their mouths.

The sight was adorable and Sunburst petted the two. He noted that Spike had also fallen asleep, snoring softly. He awwed, before looking up as Cadance and Twilight walked in, dawwing as well at the sight of the three snoozing on the couch.

“Well. it seems you’re doing a great job,” Cadance commented, watching the three snuggle up to Sunburst. “Aww, and you even got Spike to take a nap. He usually hates naps.”

Twilight got a snicker out of that, moving over and sitting nearby. She watched Starlight’s chest rise and fall gently in her sleep, the smile on the filly’s face made her smile as well.

After the nice nap and diaper changes, Starlight followed Flurry Heart down the hallway as they explored, with Twilight keeping an eye on them. The filly giggled at all the reflections she could get out of the various shiny objects around the castle, the childish joy filling her whole body. The foals soon came across one of the many staircase, Starlight pausing to grasp the sheer size of it. Sure, she’d seen stairs at Twilight’s castle, but she’d always been carried down them.

For the first time since her foal transformation, Starlight got a real grasp of scale. Her eyes sparkled at the epic quest ahead of her, as the top the stair was just above her horn. Flurry giggled, watching as Starlight stood on her chubby hind legs, and tried to clamber up onto the next step, grunting as she did so. After many tushy wiggles, she soon slid herself onto the step and beamed, looking up to see Flurry on the step above her. “Oh no fair, me no have wings.” She pouted.

Twilight snickered at the adorable act. “You can do it, Starlight.” She encouraged, clapping her hooves. Flurry cheered Starlight on as well, watching her clamber up the next stair, and then the next.

Starlight squealed with delight as she kept going, slowly ascending the staircase, while her diaper bottom wiggled in the air. It felt like forever, but soon the foal reached the top, cheering as she clapped her hooves. She took a moment to breath, as Twilight came up the stairs and patted her diaper. “Good job, little Star, such a big filly. Just a few more of them and I wouldn’t need to carry you everywhere I go.”

Starlight blushed at the praise, hugging Twilight’s leg. The motherly mare scooped her up, nuzzling her once again. “Hehe, I had fun…Mommy.” Upon seeing Twilight blush (and knowing that she’d gotten the reaction she wanted) Starlight stuck her tongue out and smiled, still snuggling the leg.

“Aww, I had fun this week too,” Twilight cooed. “Now I know how Mom felt when Shiny and I were foals,” She picked up her foal, giving a nuzzle. “Now it’s time we get ready to head back home.”

“But I want to play more.” Starlight whined, pushing on Twilight chest to no avail as she carried along upon Twilight’s back.

“Oh you had plenty of play time today,” Twilight smiled. “Besides, I need to get home to respond to fan mail.”

Starlight giggled at the thought, soon stopping her struggles and swiftly snuggling into the soft fur. “Okay.”

Starlight spent the entire train ride back to Ponyville snuggled under Twilight’s warm wing. The foal had to admit that this whole week had actually been divine, the overwhelming motherly care had made her feel so loved. Many happy memories of her actual mother came to mind, causing her to grin more. Despite how her life had turned out, at least she had a nice foalhood. That was back when her parents had made an effort to actually be part of her life, whereas by the time she was a filly they were always away, leaving her to either hang out with Sunburst or be stuck with a sitter.

Starlight had to admit, she was going to miss this gentle care and idle playtime. Maybe she could use that book again at some point, being an adult was tough at times after all. But maybe she wouldn’t regress herself to nearly this dependent a state, at least a potty trained toddler would suffice.

The stroller ride back to the castle was pretty nice, as Starlight slumped back to enjoy it. To her suprise, Pinkie was waiting in the lobby as they wheeled in. The party pony clapped, gesturing to the small table she’d set up. “Surprise!” She declared.

When the group got closer, they saw the decorated table with a small cake on top, with “Happy First Birthday” written on it in frosting (complete with a single candle). The frosting matched Starlight’s coat, and there were little star sugar bits around the edges. Twilight smiled. “Oh, Pinkie, you didn’t have to make Starlight a birthday cake.”

But Pinkie beamed. “Oh, but I just wanted to. Plus i got her gifts. I know she’s going to change back tomorrow, but then I got this amazing idea to throw a mini party for her last day. Although, you weren’t home at the time, so I changed my mind and decided to wait til you got back.” Pinkie beamed, once more watching Starlight stare at her mouth watering cake.

“Wait, you’ve been at the castle all day?” Spike asked.

“Yeah. I even cleaned up a little.” Pinkie happily confessed. Moments later the three heard a plop and the smacking of lips, all turning to watch as Starlight was digging into her cake, giggling and shoving another hooffull in her mouth.

“Starlight,” Twilight groaned seeing the foal just smile back with frosting on her cheeks.”

“Yay, she likes it!” Pinkie cheered, watching the foal eat more. She then pulled out a box of napkins. “Let the foal have some fun on her last day.”

Starlight scooped up more of the cake, happy that she’d done it this way on purpose. It was so messy and fun (plus it was just like any foal would do). Besides, at least it would get her a nice bubble bath. Once the foal had finished stuffing her face with as much as she could eat, Twilight floated out the wipes, cleaning off the squirming filly. Then the motherly mare let Starlight open her first gift, seeing a purple colored pacifier.

“Uh, Pinkie, Starlight doesn’t need more pacifiers.” Twilight raised an eyebrow in confusion.

“Oh but this one’s special, it sizes up with the wearer. You know in case, she wants one when she’s back to normal.” Pinkie explained and proceeded to pat Starlight’s head, seeing the foal blush bright as a cherry.

Starlight started at the pacifier and set it in, giggling a little at the image in her head of her normal adult self suckling on it. She then opened the other gifts, finding a sizable teddy bear, a few novels she’d been wanting to read, and lastly a pink photo album with rattles and primary shapes printed on it.

“It’s for all those photos Twilight has been taking,” Pinkie Who doesn’t like a cute baby pictures photo album?”

Starlight beamed once more, giving Pinkie a hug as tight as she could manage. “Thank you, Pinkie!” She lisped.

“Aw, I knew you’d like them,” Pinkie gave Starlight a big hug in return, patting the diaper and noticing the damp feeling. “Oh, seems somepony need a diaper change,” She sing-songed, hoofing the foal back to Twilight. “Sorry, I’d love to stay and help but I should be going, the twins will want to see me before bedtime.”

Starlight cooed and wave a hoof as Pinkie moved to the door. “Bye bye.” She was then carried along as Spike helped run a bath getting a rubber ducky and bubble bath. Twilight undressed her foal and lowered her in gently scrubbing the foal. The filly occasionally splashed about or squeak the rubber duck making the most of the bath time. After she tried off and slipped into a fresh diaper, she was carried along, snuggling her new teddy bear as to the same bed room this adventure had started in. The foal shifted, getting comfy once laid down upon the soft mattress watching the safety rails be raised once again.

Twilight let her foal get settled, before floating the bottle down and into Starlight’s mouth, holding it up for her. She relaxed, watching the milk slowly drain and feeling happy as the foal’s eyes droop, her limbs slumping into the mattress. “Sleep tight little filly.” Twilight whispered, soon dimming the light and waiting for the bottle to drain. As expected, the filly had dozed off soon after finishing and mumbled in her sleep. The new pacifier was set between her lips and with everything settled, the caretaker exited the room.

Author's Note

Just one more chapter to go as we wrap things up. :) Was lots of fun writing this.

All Grown Up

Starlight awoke the next morning feeling refreshed and better than ever. She smiled remembering her dream about puppiess and let out a small giggle at the thought. As she did, she felt a familiar sensation of the pacifier in her mouth and went cross-eyed, peering down at the purple handle. Pinkie’s gift had as she’d been told grown with her and now fit her mouth perfectly.

The now big foal couldn’t help but grin, letting out another childish giggle before sucking on her pacifier contently. Several moments passed as she felt content to just snuggle under the sheets and stare up at the sparkling ceiling, keeping the pacifier bobbing. The thought of staying till her mommy came in to check on her came to mind but she shook her head and blushed. “Don’t be silly, Starlight, you’re all grown up now. You don’t need to be checked on.” The thought only made her feel more embarrassed, as she almost hesitated about her own wondering fantasies. Another minute passed without much happening as she lay still and sighed, realizing she was starting to get hungry. She shifted just not feeling the odd squishy feeling. “Wait, that can’t be right!” She thought.

She had been diapered last night for sure, but there no way that the tiny thing would have stayed on a grown pony, let alone one that was rapidly aging up. She paused for only a moment before pulling the sheets aside and squeaked, cheeks going red as an apple at the sight. The diaper looked soaked from front to back, still hugging her rump. It would appear the magic left her body in the most natural way possible, quite fitting giving the situation.

A second thought of letting Twilight get one last diaper change came to mind, as she slowly climbed out of bed and giggled once more. Twilight had been great this past week after all. Just as she considered taking it off, Twilight came into the room.

“Good morning, Starlight.” She beamed glad to see her student was back to normal. Her eyes soon spotted the diaper and the state it was in. While she stared, she could hear her foal suckling on her pacifier. She took a moment to think of what to say, unable to not smile as Starlight just stared back at Twilight with a sheepish grin. After a few seconds she just reached over and patted the seat of the soggy diaper. “Aww, such a big filly.”

“Hehe, yeah. At least the magic wore off,” Starlight shifted side to side, backing up a few steps while feeling self-conscious. “I, well, just thought that you might like one more chance to change a diaper.”

Twilight tried to stay somewhat serious but couldn't manage to break the motherly mode she was going for. “Oh, is litte Star still needing Mommy’s help?” She snickered again and was about to speak up, only for her laugher to be joined by Starlight’s own. Once their laughter had settled down, Twilight spoke again. “Besides, your mommy should have had you potty trained years ago.“ Upon seeing her student’s blush grow deeper, she smiled and put a hoof over Starlight’s shoulder. “Sorry, couldn’t help it. How are you feeling?”

“Fantastic actually. You made my week as a foal rather rewarding,” She meeped a moment later, realizing she still had the pacifier in, and took it out with a quick pop.“I rather enjoyed it, and you’re a great mother too, Twilight.“ She’d been so caught up in her gratitude, that she had hardly noticed Twilight using her magic to take the soggy diaper off, and wipe her student clean, before tossing the used undergarment away.

Twilight patted her student’s head motherly while blushing. “Aww, thanks. It came naturally, surprisingly. You were just so cute, plus the experience was delightful.” The princess could still smell the foal powder stuck on Starlight’s coat, but let it slide. The quiet moment was soon broken though, as Starlight hugged her, before pulling back.

Starlight rubbed the back of her neck, turning her head to looked out the window. She moved her lips, trying to say what was on her mind but felt a wave of embarrassment wash over her cheeks again. Twilight stood there waiting, and gave her time to contemplate. “W-what if I wanted to be a foal again?”

“Again? What do you mean?” Twilight asked, watching the pacifier dangle from Starlight neck.

“I mean just acting like a foal at some point. It’s relaxing, and could be fun,” Starlight confessed. The memories of the week came to mind, the simple pleasure of making towers of blocks or scribbling art was just so pleasant, and without worry. She let out a chuckle. “I mean at least when I’m big, you won’t have to deal with messy diapers. I can just use the bathroom,” The shifting grew a little more. “You’d like to be a mother again too, I bet?”

“Well I’d be lying if I hadn't been thinking about last week,” Twilight acknowledged, and she watched as Starlight bounced up and down like a child. “I guess we can do it when you’re in the mood. Might make a nice friendship lesson about trusting others.”

“Oh thank you, Twilight!” Starlight squealed, giving her friend another hug before setting the pacifier back in, causing it to bob in and out. “You know, I wouldn’t mind another adventure at some point. Where is that book anyway?”

“It’s just in the library. I was looking it over and it turns out that there are other adventures in that book beside the one we went in.” Twilight explained.

“Like Daring Do kind of adventures?” Starlight asked.

“Yeah and even a zompony apocalypse one I think,” Twilight watched the big foal suckle the pacifer more, before taking Starlight’s hoof and tugging her along like a mother. Seeing no signs of a protest she kept leading. “Now come along Starlight, it’s time to eat.” The princess cooed.

As they entered the hallway, the two ponies heard Spike yelp from the library. Twilight reacted instinctively, and rushed to the door! “Spike are you okay?!” Hearing no reply, she turned the knob!

Upon opening the door, Twilight began to snicker a bit. Spike was standing by the open adventure book, sporting a thick white diaper with gem patterns, and a bonnet tied around his neck. He held in his claw, a rattle like version of the dragon scepter. The dragon groaned and blushed heavier, trying to drop the toy but only making it rattle. “Gah, can’t let go!” He lisped around the pacifier planted in his mouth.

“Aww, did Spike peek into a diary again?,” Starlight teased, well aware it wasn’t the case.

Twilight came over and with the help of a little bit of magic was able to open Spike claw, and set the rattle on the table. “I take it you got sucked in and went on some adventure too?” She asked, resisting the urge to daww at the attire he was in.

Spike spat the pacifier out, gushing with embarrassment. ‘Y-yeah, was really weird but oddly fun,” The next moment, he felt Twilight’s hooves scoop under his armpits. He let out a squeak as she supported his weight like a baby! He blushed. “T-Twilight, stop it! I can walk fine.” He stood there, not taking a step, too shy to do such an embarrassing thing.

Starlight snickered, admiring how motherly Twilight was being (even if it was also teasing). She clapped her hooves lightly. “Come on, Spike, come to Starlight.” She tried her best to keep a straight face.

Spike groaned, indicatively wiggling to no avail, and soon began to waddle towards Starlight with ‘help’ from Twilight.

“Oh, he’s growing up so fast,” Starlight cooed, slowly backing out of the door as the baby dragon was led along. This little game felt rather fun, and just to top off the childish activity, she proceeded to stick out her tongue and maKe faces at Spike.

“Starlight, stop it!” Spike whined, as Twilight continued to walk him along the hallway.

As Starlight led them both along to the kitchen, she was filled with a joyful glee over having a new mommy of sorts. Even if it would only be once in awhile, they had made this connection. Twilight was always looking out for her before, but now it was different. They were a family, she just hadn’t seen it until now. Whatever wacky adventures were to come, at least she’d have them by her side. “Come on, Spike, follow your big sister.” She let out a laugh, embracing her new look on life.

Yes, Spike Story will be coming. Should be fun

Shopping for foals

The next morning went pretty smoothly for the little filly. Diaper change, oatmeal for breakfast, and of course some milk to wash it all down. Twilight wasted no time in preparing to go shopping. Starlight was currently sitting next to Spike on the floor with some toys in front of her. She nudged one of the blocks, gumming on her pacifier a little. The little one began to make a small tower, mostly to just to occupy her time, though the colors seemed amusing to her now, so there was that. The activity only lasted a few minutes however as Twilight soon came in and picked up Starlight, doing another diaper check.

“All clean little one, such a good filly. “ Twilight nuzzled again getting a light giggle out of the foal along with a slight blush.

“Y- you just checked me 15 minutes ago!” Starlight whined, being placed into a carrier hanging from Twilight’s side.

“Ah ah. Mommy Twily can't be too careful. Don't want you to get a diaper rash.” Twilight patted the foal’s head and headed out, with Spike following behind with a check list. Starlight had to admit dangling there while not having to worry about anything was relaxing. Her padded rear would crinkle with each light bounce her caretaker had in her step, causing her to wiggle some.

Spike watched her silly movements before looking at the list. “We should only need one package to last the week. Well assuming little star here isn't a piddle pants. “

“Mmm, you wouldn't be making jokes if you were padded,” Starlight pouted, looking cute as she kept her pacifier in.

Twilight looked back motherly nuzzling Starlight as they stopped by the entrance to the foal store. “You know she’s right, Spike. You shouldn't tease her for something she can't control. And besides, you looked pretty adorable in a diaper in that other world.”

Starlight snickered, putting her hooves to her mouth. “Yeah, he did.” She stuck her tongue out at Spike, making the drake blush as they made their way inside.

The shop had a lovely lilac smell to it with a mix of plastic. Vibrant colors were around every corner, giving the store a preschool like feel.

Spike pulled the list out, a pencil clutched in his claw. “Well, given that Starlight is only going to be a foal for a week, I think two packs is enough, Twilight. I don't think we need five of them given they are packs of twenty-five.” He tilted his head, looking at the stuff in the aisle.

“I suppose so, never know. Like you said, she might be a heavy wetter. Besides any that we don't use, I can just give to the Cakes. “ She stopped to nuzzled Starlight, the little one blushing as she suckled the pacifier, seeming content for the moment.

Spike crossed his claws. “Oh, so you can tease but I can't?” He said childishly.

“Of course I can, I'm her mommy. Besides, I didn’t call her a name.” Twilight stuck her tongue out, while floating a few brands down, admiring the various patterns.

Starlight took a moment to look at Spike, snickering. “Careful, Spike, Twilight might think you’re a baby again. Well, more of an actual baby.” She wiggled her hooves, looking at the packages as well. The one Twilight was focused on was light pink, with purple stars printed on it. The only way those could get anymore embarrassing. was if Twilight were to print her cutie mark on the seat for all to see. Starlight had no doubt she could do that without hesitation, given how much she seemed to love being a mother. The little filly’s blush grew as she imagined herself waddle around in such a thing, as opposed to the plain ones she was currently in.

“Aww, I think Starlight likes them, Twilight.” Spike teased, ruffling the foal’s little pig tails.

“No! Too embarrassing!” Starlight covered her face, cheeks burning as red as a cherry. Her caretaker picked her out of the carrier and nuzzled nose to nose to cheer her up.

“Aww, but you'll look simply adorable, yes you will,” Twilight cooed, dismissing her foal’s embarrassment. Her hoof prodded the diaper as she checked once again. “Uh oh, seems little one is wet again. “ Starlight just whimpered in response, still hiding her face as she was set into the carrier again and taken along as they picked up more items, stopping by the washroom to change her. Being stuck with a rash would have been the cherry on top of the humiliation sundae. Along with the pack of diapers, the foal could see a few new toys and a small can of powdered formula. “Was Twilight always this good handling foals, or is it that magic helping?” She thought, whole spotting a pile of teddy bears.

For whatever reason, as the group neared the pile, Starlight felt like she really wanted the yellow colored bear with pink colored pads and tummy. It reminded her of Fluttershy. Seeing that Spike and Twilight were occupied with looking at some pastel bibs, the filly grunted getting her horn to light as she focused on the bear. Given her small size, the strain was far greater, but it was just a levitation spell, one of the easier spells to master. She grabbed the bear by its arm, slowly lifting it up like a claw machine.

As more of the bear was lifted out, Twilight saw what her little filly was doing. Seeing no harm in what she doing, Twilight let the foal continue.

Just as it was lifted off the shelf, Starlight panicked as she felt a sneeze coming on. It happened far too quickly, causing her to drop the spell and upon sneezing she felt a rush of air! She squeaked, keeping her eyes shut, afraid of what she had done! But instead of being scolded she heard the two laughing. She slowly opened her eyes and blushed noticing, she had sent the shelf of plushies flying all over the place, making quite the mess.

“Hehe, wow! She’s about as messy as Flurry. “ Spike commented.

“Aww, it's okay little star, Mommy isn't mad,” Twilight cooed, lifting Starlight out of her carrier. Despite the soothing words, Starlight couldn't stop blushing. But the princess kept snuggling her, using her magic to float the teddies back in place. She took the yellow colored one and offered it to Starlight. “Is this the one you wanted?”

Delighted, Starlight took the bear and hugged it close, sighing with a sudden sense of bliss. “Thank you.” she lisped.

After they had bought everything, and Starlight had been changed into one of the pink colored diapers to see how they fit, the group headed back towards the castle.

Along the way Twilight dropped by Applejack’s fruit stand, pulling out some plastic keys while she spoke. “Hey Applejack.” She greeted, jingling the keys above Starlight, who was in a new pink colored stroller they had bought as well.

“What happened to Starlight?” Applejack asked as she approached the little filly. The odd flow of magic pressed lightly on the farmer’s perception of reality a bit, and she couldn't help but chuckle as Starlight seemed fixated on the colourful toy, batting at it with her hooves to try and get the keys.

“Well, it’s a long story, but Moondancer had this book that apparently had magic similar to Spike's comic.” Twilight explained.

Applejack nodded. “Oh, I remember when that happened. But how’d that make Starlight a foal?” She took the keys from Twilight and kept jingling then for the foal, smiling at the squeaks and cheers.

“Well we all sort of ended up as foals while inside, and since Starlight ended the game it rewarded her, more or less.” Twilight told Applejack, drawing on what memories she could recall.

“Oh,” Applejack replied. “Well, hope it ain't permanent. Even if Starlight’s plum adorable in this state.”

“Not to worry, it’s just until the end of the week,” Twilight reassured her friend. “And in the meantime, I get to be her mommy.”

Meanwhile, Starlight’s horn glew, as she yanked the toy from Applejack’s hooves and shook them about by herself. “Mine!” She squealed!

Applejack was a little startled, but let it be as Twilight scolded the filly. “Now Starlight, that wasn't very nice. Say you're sorry.” The foal just looked up and stuck her tongue out, her pacifier hanging from her neck as she resumed rattling the toy around, seemingly entranced by it.

Applejack snickered. “Uh oh, Twilight. Looks like ya got a rebel on your hooves!” She teased. “Applebloom used to be the same way.”

“Isn't she still kind of like that ?” Spike quipped.

“She might be a bit rebellious from time to time, but she’s growin’ up well.” Applejack explained, ruffling the foal’s mane. The disruption was enough to snap Starlight out of her trance.

“Huh? What?” Starlight blushed harder, letting out an eep.

“Oh, did I distract ya from your playtime?” Applejack mothered, lighting bopping Starlight’s nose.

Starlight squeaked, covering her nose with a hoof. “Uh, hi Applejack. I-I am not a foal!” She blushed, even if her size spoke to the contrary.

“Oh, don't be silly, little one. You’ll be big someday soon, but for now, you’re just the cutest little filly I've ever seen,” Applejack cooed, the words left her mouth naturally, as Applejack tickled Starlight’s tummy a bit.

“No fair, this magic is cheating!” Starlight thought, even as the little filly began to giggle and kicked her hind legs about. When the tickling stopped, Starlight pouted again but not as grumpy as before. The attention was nice, even though she didn’t want to admit it..

Applejack giggled, getting Twilight her bushel of apples. “Starlight’s so cute when she pouts,” Starlight protested with a whine, only to be unbuckled and scooped up into Applejack's hooves giving the foal a hug while supporting the diaper. She watched as Starlight slowly smiled and cuddles into the warm fur. “See? All she wanted was to cuddle.” She rubbed Starlight’s back, as Twilight and Spike watched.

Starlight didn't stop cuddling once she settled in, feeling comfort as she leaned on the warm fur. The farm pony pat her back some, before hoofing her back to Twilight. The little filly caught herself trying to reach out to Applejack and quickly put her hooves down. “Stop it! Ugh! Why is slipping into the foal mindset so easy?! This magic is pretty strong,”She thought, and squeaked a little when Twilight nuzzled her. “Okay, the attention isn't all bad I guess, but does it have to be so embarrassing?” She thought, but out loud she asked Twilight.“Where to now?”

Twilight held the foal to her warm chest and looked at the list in Spike’s claw. “Just a few more things to buy,” She cooed making sure her foal had her pacifier. “And this time, you get to ride in the basket.”

Despite trying to act more like an adult, Starlight can't help but bounce a little as the shopping cart was wheeled down the aisle. She hugged her new teddy, beaming as she looked around, while Twilight picked out ink and the like from the various shelves of the grocery store. A few ponies look at the grayish-purple colored unicorn and smiled when Starlight waved back at them. The cart was a little least embarrassing then her stroller which spike was pushing behind them.

By the time they were heading back to home, Starlight began to yawn. Her tiny body needing to nap. She kept a hold of her plushie friend as she laid back in her stroller sinking into its comfy embrass. Spike dawwed, “Don’t worry, Starlight. We’ll get home soon, then you can nap.”

Starlight nodded slowly as she yawned, the gentle rocking as she pushed along helped l to lull her to sleep. By the time they had arrived at the castle, she was fast asleep mumbling in her sleep with a smile.

As Twilight took Starlight to bed, she heard her mutter about mommy and other such things. It snapped Twilight out of the trance for a second as she thought about it. She’d never really asked about Starlight parents. Now that she thought about it, where had Starlight’s parents been when she revealed her past? Surely they would’ve tried to help their child cope with the loss of her best friend, no? Oh well, those were all questions for later, Twilight supposed. Starlight was soon laid down on the mattress and tucked in under a pink, fuzzy blanket. Twilight stood there for a moment and simply watched, feeling at peace keeping care of her charge. It was going to be a nice week, she could tell.
