Twilight groaned as she rubbed her head and looked around at what appeared to be a nursery. The mare turned little filly blinked as she looked down at her body. She now had a grey coat and there was a poofy white diaper with some cute little pink hourglass patterns strapped around her rump. Patterns that were quickly disappearing due to her diaper’s damp condition. The filly blinked as she turned to see Dr Whooves across from her sleeping in the same crib. She was quite surprised as she turned over to the colt. “Pssst! Hey…”
Dr. Whooves whimpered as he turned to Twilight with a smile. “Hey, you had a good night's sleep?”
The little filly climbed over the crib, showing off her soaked diaper and snapped. “What's going on? Why am I a foaw and why is my coat a different colow now?”
Dr. Whooves yawned as he stretched his hooves, showing his diaper was also soaked as he slowly got up. “Oh, that’s so we can sell it to the other foals that you’re my sissy and not ‘Twily’.”
Twilight squeaked as she stammered. “Seiwouswy?! Ten who’s gonna be owa mommy?!” And she blinked. “Why did I tawk so funny just now?”
“Ya a foaw now, so you gotta tawk wike a foaw to not wook suspicious,” Dr. Whooves explained as he spoke in the same lisp. “Now be quiet, owa mommy’s gonna be here soon.”
Twilight then turned to see a mare that looked like Dr. Whooves come into their nursery. The mare in question was a brown coated pegasus with her wings folded to her sides, bright blue eyes, and a pink tie around her neck as she waved a hoof. “Hello, my little foals!” The two foals both squeaked as they were raised up for diaper changes on a changing table.
“Now, Dr.Whooves, did you explain the whole situation to Twilight?” The mare cooed. “She looks rather confused.”
“Not weally, sowwie, didn’t gots awot of time to say what was happening,” The little colt giggled as his rump was cleaned with wipes and freshly powdered. “Is funny to tawk wike this. Now I can tawk to foaws without tem thinking I weird.”
The older mare got quite frustrated and snapped. “Ugh, really? You were supposed to explain everything to her before she got here,” She turned to the little chubby Twilight as this alternate version of Dr. Whooves started the diaper change, unstrapping Twilight’s soaked padding and wiping her down as she explained. “I’m so sorry about all of this. You’re probably quite confused right now. I wish my partner would’ve explained things better. My name is Time Flies by the way, but just call me Timey.”
“Ok...Timey,” The little foal was quite nervous as she asked. “So, is tis Stawlight Glimmew twying to make me stay as a foaw forevew?”
Timey sighed as she shook her head as she replied. “Look, I’ll brief you on what's going on soon, ok? And trust me, if everything goes well you’ll only be a foal for a day.” The mare then picked the foals up onto her back and trotted downstairs.
Twilight squeaked as she kicked about in her pampers. Seeing so many other ponies turned into foals, she should’ve guessed it was only a matter of time before she would be wearing diapers again. It was such an odd feeling being in a diaper, as it was rather comfortable and snug around her rump.
The mare then placed the two foals into two highchairs and slipped bibs around their necks. Timey giggled as she chirped. “Alright, now for breakfast!” A bowl of oatmeal was nearby, and she took a rubber spoon as she started to spoon feed the two and sent the glop into their mouths.
As the two chomped down on the foal food. Dr Whooves seemed to be used to this munching away. But for Twilight it was odd not having teeth as she smashed the foal food in her mouth, swallowing it down and getting it all over her face.
Timey dawwed as she slowly wiped their faces. “So Dr. Whooves, I heard you were a baby for a while? And then even diaper dependent as an adult for a month?!”
“Y...yeah, guess ya can say I used to being in diapews,” The doctor sighed as he scrunched the padding around his legs. “I even had to teach twins about ta potty.”
The mare snickered behind a hoof. “Oh, don’t be so embarrassed, you always were such a cute foal. Now come on and finish your breakfast.” She then continued shoving more oatmeal into his mouth along with Twilight. After the two had finished their oatmeal, she plopped two bottles of formula into their mouths as they suckled the chalky formula down their throats.
Twilight squeaked at the taste. It was actually really good! No wonder Celestia, Luna, Cadance and Shining had loved this stuff during their regressions, it was so creamy and sweet. She barely even noticed she was sucking down air from the bottle until it was removed with an audible pop.
After their mouths were wiped the foals were picked up from their highchairs, and placed down in a playpen as Timet got out a chalkboard, rolling it in front of the two as explained. “Let me explain everything, Twilight. Dr Whooves and I are a part of Whooves Space and Time Bureau. Our job is to protect the space time continuum and ensure that no one interferes with it. We recently noticed a time rift caused by Starlight Glimmer, who is heading here tomorrow. Our job is to stop her from giving you, Twilight Sparkle, a potion that’ll have you remain a foal indefinitely.”
Twilight gulped, If she stayed a baby forever she was sure she’d never meet her friends and Nightmare Moon, Midnight or Discord would take over Equestria. As the mare turned foal thought this over in her head Timey continued to explain the situation.
“While on this mission, I'm posing as your mother and you two and Dr. Whooves are my twin foals. I can understand your foal babble but no other adult can. However, that also means you’ll be able to communicate with the other foals that'll be with you at the daycare,” Timey then warned them. “You cannot tell any one of them your true identities, you’re just average, one year old foals. We’re to stop Starlight from giving Twilight the potion, snatch it and send her back to her original timeline. Once we're done, we send you, Twilight back to your original timeline as an adult and our mission is complete. Pretty simple really, now are there any questions?”
Twilight raised a hoof as she waited to be called on.
Timey giggled as she asked. “Yes, Twilight?”
“Got a few questions...um...bout me I guess…” Twilight commented. “Ya see, I guess we gotta be awound me as a foaw, so I feel as if I shouldn’t be hewe, wight? I could mess up ta timewine by even tawkin’ to her, wight”
“Well as long as you don’t tell her you’re Twilight you should be fine,” Timey answered. “That reminds me. You and Dr. Whooves will have code names to avoid attracting suspicion,” She pointed a hoof at the baby version of Twilight. “Dr. Whooves will be Choca Butter and Twilight will be Muffin Top. I should’ve explained earlier, my codename is Sweet Bread and my fake backstory is I’m a baker that recently came here to start my own bakery with my husband.”
“Muffin Top?!” Twilight whined, being quite disappointed in her name.
Timey laughed as she flapped her wings and explained. “Yep, my husband picked that one out for our first daughter. Now, your goal today is to observe baby Twilight and the schedule of the daycare. We need to know what she does, and make friends with her mom/your mom, Twilight Velvet. My job then will be to have you two sleepover at their house tonight to make sure Twilight is watched the whole time. All we know is that Starlight will be here tomorrow and we have to be there to stop her no matter what it takes!”
“Right!” The foals chirped as they were picked up and strapped in a two seated stroller.
“Now, Dr. Whooves has done this a few times actually,” Timey explained before looking to Twilight. “But Twilight, this is your first time as a baby so you have to act the part. That means use your diapers, play with the other foals and don’t be afraid to get messy.”
Twilight sighed as she scrunched her pampers, feeling embarrassed that she’d be using diapers all day as she asked. “Yeah, yeah I got it...tough, why did ya give me a gwey coat?”
“Oh just to make you more like me. Ponies might find it odd that you're my daughter being a unicorn. But I'll tell them I do have a few unicorns on my mother’s side.” Timey explained with a smile on her face.
Just then an earth pony stallion came through the door. He had a grey coat with gold eyes and a short blonde mane and tail. He was rather chubby with a chef’s hat on his head and an apron tied around his body. “Hey! Your um Time Space buddies set up our shop! Everything is good to go!” He then turned and dawwed at the two. “You made Twilight look like our daughter, she's perfect!”
Timey flew over and nuzzled the two as she made sure they were snug in their stroller. “Well, it can sell our little fantasy more easily, right? We do have twins that look exactly like them at home.”
Twilight blushed as she asked. “So, ya ta male vewsion of Dewpy, wight?”
The stallion scratched his head, looking confused by Twilight’s response. “Um well my name isn’t Derpy, it’s Derp o Muffin Top...but friends call me Derp for short.”
Twilight giggled at the silly name. “Weww, guess ya my fake dad.”
“Yep! And you two look exactly like my foals in our dimension! Timey keeps trying to explain everything but I don’t follow…” He blushed while looking down, feeling a bit embarrassed for not really knowing what was going on.
Timey nuzzled him. “Oh stop, not everypony needs to be super smart. I love your baking and you're an amazing dad. But I just don’t want you having to worry about not messing up the timeline. So all you need to do is sell muffins that should only cause a few minor differences in the timeline, nothing major. What Starlight is planning could alter history all together.”
Her husband nodded as he kissed her and Dr Whooves blushed. “Is so weiwd being babied by an awternate version of yasewf and your wife.”
Twilight sighed as she looked upwards. “Yeah, it's wather cute, but I tink that what I’m gonna do is weird. I'll be the first pony eva to actuawwy meet mysewf as a baby.”
Dr Whooves blinked as he tapped a hoof to his chin. “Ya wight! Tis quite a histowical moment.”
Twilight scrunched the padding between her legs with a blush growing on her face as her diaper started yellowing again and she squeaked. “Maybe this is one of those histowical moment betew weft buwied.”
Dr Whooves laughed at Twilight soaking her diaper and exclaimed. “Nah uh! I gonna wecowd ya with ya weaw baby sewf! It’ww be interesting on what ya two tawk about.”
Twilight blushed. “Yeah, maybe...tough befowe I went ta Ponviwwe I wasn’t ta nicest pony. I hope tat if anyting, maybe I can teach hew abit about fweindship and not be so bossy. Otherwise, being my fwiend is gonna be hawdew ten it wooks.”
