Momlestia comes to the rescue

Fluttershy was back in her hut, drinking a nice cup of tea, quite relieved after all the craziness with Philomena that she hadn’t done anything that had harmed the princess’s pet. The pegasus sat back, still thinking about how Philomena had scared her half to death. “It's almost a relief that this was just one big misunderstanding, but I can’t believe that Celestia's bird pretends to be sick.” She thought aloud.

Fluttershy turned to Angel, seeming to be quite annoyed she was back already from the lunch with Celestia. She laughed as she turned to the bunny. “Oh, I bet you wanted the cottage to yourself, huh?”

Angel rolled his eyes as Fluttershy continued to enjoy her teacup, still feeling relieved that nothing terrible happened to Philomena. But then the mare squeaked as she felt her body starting to shrink. Her muscles contracted as the chair beneath her rump seemed to be coming towards her. The pegasus then tumbled onto her seat and fell backward, her hooves now looking quite pudgy and seeming uncoordinated.

She tried to walk but it was more of a clumsy waddle. The now little filly squeaked as her hooves were relatively uncoordinated, and she continued to plop onto her rump as she headed towards a mirror; looking up and gasping upon seeing her reflection! Her plump cheeks, chubby belly, bulging baby blue eyes, tiny little wings and blank flank indicated that she was a foal!

Celestia sighed in relief as she rested comfortably in her chariot. She turned to Philomena and brushed her bird. “Can’t believe you caused so much trouble, young lady. You nearly gave Twilight and Fluttershy a heart attack.”

Philomena threw a wing over its beak and snickered as Celestia gave her pet a few more strokes through her feathers. One of the guards ten looked over and asked. “Princess Celestia, are you ready to go?”

“Oh, yes, let’s leave,” Celestia replied. Yet as soon as the carriage had lifted off, the princess realized something was off and her eyes suddenly lit up. “Oh my me! I forgot about what sometimes happens to ponies who are exposed to a phoenix’s rebirth!”

The royal guards both turned around, looking quite surprised as the princess shouted. “We need to go to Fluttershy’s hut, now!”

The guards were quite concerned as the princess got up. “I need you two to go get some packages of foal diapers, wipes, foal powder and maybe a plush bunny...also get some pull-ups for colts just in case.”

Both of the guards gulped as one asked. “We were exposed too?”

The princess's cheeks flushed with a chase of pink. “Yes, I apologize for not telling you about the dangers of Philomena’s rebirth sooner but it completely slipped my mind. Please just do as I ask, I'll take care of everything!” She then took Philomena's cage into her mouth and flew off through the air heading towards Fluttershy’s cottage.

The alicorn princess was soon at the pegasus’ cottage door and knocked while shouting, “Fluttershy, are you ok?!” The princess didn’t hear anything but a strange amount of cooing and babbling. Celestia was quite surprised as she slowly opened the door and looked around the room. On the ground was a small, yellow coated pegasus filly.

Celestia sighed. “Oh dear...I should’ve known this would happen,” The alicorn slowly came over to pick up the pegasus and nuzzled her as she then cooed, “I know you probably can’t understand me, but being so close to Philomena for so long you were exposed to some of her magic, which in this case caused you to regress in age. This sometimes happens to ponies who witness a phoenix’s rebirth.”

Celestia then turned to see Twilight burst through the door as she exclaimed. “What happened, Princess?! I saw you fly across the sk-” Then the mare’s eyes went wide as she saw Fluttershy was now a little baby, waddling aimlessly with Celestia standing overhead with a blush as she whispered. “Oh no...I forgot you were exposed to Philomena’s rebirth too.”

Twilight blinked. “What are you sa-” Before she could say anything further though, she felt her body shrink and squeaked as she plopped down on her rump. Her body slowly bloated out as her limbs turned stubby and stocky.

Celestia took the little filly within the hold of her magic. “I'm so sorry, I forgot to mention earlier that if ponies are exposed to a phoenix going through its rebirth cycle, they may regress. Don’t worry though, it's only temporary. You'll be back to your normal age in a few hours,” Then she snickered, turning to Fluttershy wadding about and blowing bubbles through her mouth as she dawwed. “I guess this is a suitable punishment for Fluttershy for kidnapping Philomena.”

Fluttershy giggled and clapped her hooves, before Celestia saw the filly had left a puddle on the ground. “Oh my, of course you’d lose control of your bodily functions too. Hopefully my guards will be back soon with protection.”

The royal guards did return, but they had now shrunk to toddlers as they waddled through the door, carrying saddlebags full of foal supplies. One guard looked at his stubby form and asked. “Princess, what happened to us?”

Celestia blushed, “I am so sorry I forgot to mention you would regress due to being around during philomena’s rebirth. You were less exposed and were turned to toddlers; so that's why I had you also get pull-ups.”

The other royal guard gulped as he asked. “B...but, do we need pull-ups?”

The princess nodded, then took the two colts and slowly placed pull-ups around the toddlers' rumps. Then she took out two cute looking diapers with little pink rattles on the padding and went about diapering up the foals in her care. “There you go, now there won’t be any more puddles to clean up.”

Twilight gulped as she saw that glint in Celestia’s eyes, knowing that they were going to be babied until the effects of Philomina’s rebirth wore off.

Princess Celestia went about going through the necessary foal supplies that the guards had brought out. “Hmm, guess we can use a few more toys...and I think both me and the foals would go crazy if I were cooped here with just four foals to watch. ”

She turned to see her toddler guards already running around, knocking stuff over, and quickly scooped them up. “Hey, stop that! This isn’t your house!” She held the two colts close as they both grumbled. “Ok, princess. We sorry.”

Celestia then spotted Twilight and Fluttershy crawling across the floor, chasing Angel across the ground. He hopped over to Philomina and crawled on top of her as he hid behind the bird’s wings. Celestia scooped up the fillies. “Stop pestering Angel, you two, that's not nice!” All four foals were now in her hooves as they kicked and whined, getting all antsy.

The princess quickly got out pacifiers and plopped them into each mouth of her four charges, placing them on a couch as she started to tickle them with a wing, making them giggle and coo as the princess pondered on what to do. “It would be strange for me to go out with foals, and the paparazzi will be on me...I have an idea.”

She then stopped the tickling as the princess stepped back with all four foals looking quite confused on what was going to happen. The princess then lit her horn, and her wings disappeared and her horn shrunk down, her mane turned bright pink and her cutie mark turned into a smiling sun. The newly transformed princess struck a pose. “Tadah! Meet my alter ego Sunny Days,” The foals were all stunned at Celestia’s disguise as she explained, “I was saving this for Twilight, but this is a better opportunity to reveal this little surprise.”

The unicorn blushed, seeing how cute and straightforward Celestia looked in her simple unicorn disguise.

“Now come on, let's get going to the store; it seems we're going to need a lot more supplies,” Celestia replied as she scooped the two fillies on her back, then turned to the toddler guards and asked in a motherly tone. “Now, do you two mind holding my hoof? I don’t want you getting lost or hurt.”

The two regressed guards groaned but grumbled. “Ok, princess.” They said as they latched onto the alicorn’s hoof and followed her out of the cottage.

Celestia continued her walk towards the store as Fluttershy and Twilight both were babbling adorably; one of the toddler guards looked up at the two foals. “Um, Fluttershy, is it?”

The pegasus looked down and waved a hoof as the other guard whispered. “We sowie for being rude to you before. We didn’t know you were one of Celestia’s guests.”

The pegasus blushed as she babbled. “Is otay, ya was just doing your jobs.”

Twilight shrugged. “I thought I gave you guys ta guest list earlier, and ya knew who was invited?”

“Yeah, I tink tat we lost tat list or something.” One of the guards whispered.

Twilight scoffed. “Tats not good, ya gots to keep that stuff.”

“Um...what's your names?” Fluttershy asked

One guard stood up on his hind legs. “My name is Silver Wing!”

The other colt blushed. “I Braveheart…”

Twilight nodded. “Well, ya two been around Celestia ta most. Um, what she like?”

They both blushed as Silverwing responded, “She wuvs being a mommy…She and Princess Wuna talk about babying ya aww ta time and Rainbow Dash, Rarity and Pinkie Pie.”

Fluttershy’s eyes went wide. “Really!? Why is tat?”

Before Twilight could explain, Celestia placed the two padded foals into a shopping cart and turned to her regressed guards. “Stay by me, and don’t let go, okay?”

Silver Wing whined. “But we supposed ta be protecting ya!”

“Yeah, we royal guards!” Braveheart cried out, and many shoppers nearby dawwed as Celestia ruffled their manes.

“Yes, you’re still royal guards. But for now you’re toddlers and I’m your mama, so please behave and stay close to me.” They both wanted to throw tantrums, but Celestia instincts kicked in, plopping pacifiers into their mouths and leading them through the store. The princess hummed while going through the aisles, picking up toys for the fillies like plush animals and foam blocks while getting foam swords and spears for the colts.

As they were scooted about, Fluttershy turned to Twilight, who was getting a bit fussy. “Ugh! I still can’t believe that ya kidnapped Tia’s birdie! Now we foaws, and worse ya might’ve just made me worse despite all ta efforts Wuna did trying not to make me wet ta bed!”

“Sowie, Twily, I didn’ mean for tis ta happen.” Fluttershy whimpered as she started to tear up.

Twilight gulped as she saw her friend starting to cry. “W...wait, I didn’t mean for ya to cry. I just stressed out.”

The pegasus nodded and wiped the tears. “It's otay. I get it, tis has been one crazy day...tough being a foal isn’t tat bad. Chasing Angel was fun, and these diapers do feel good on my rump.”

Twilight laughed.” Angel was fun! He was such a cute bunny, tough Tia was wight, we probably shouldn't have done that.”

Fluttershy cheeks flushed pink as she whispered. “So, when ya was a big pony, ya wet ta bed?”

“Ye...well...yeah…that's not ta point.” Twilight whimpered, scrunching her padding while feeling so embarrassed at telling the last one of her friends about her embarrassing predicament.

“Oh? When did ta bedwetting start?” The pegasus filly asked, getting quite surprised while bouncing on her padding.

Twilight sighed. “When we defeated Nightmare Moonie, I started peeing ta bed at night.”

Fluttershy sat closer to Twilight and nuzzled her. “Why did you keep tat a secwet? Ya know tat we friends.”

“Well..I...I was embewassed, I didn’t want anypony ta know.” Twilight whimpered, kicking about.

Celestia noticed the foals talking; she didn’t understand what they were saying and bent down as she nuzzled her student. “You were telling Fluttershy about your little secret...well don’t worry, the regression shouldn’t make you wet the bed more or have day accidents. You’ll be back as a big bedwetter by tomorrow. And then maybe we can work on the re potty training.”

Twilight whined and babbled angrily as Celestia laughed as she headed to the cash register and bought the foal items.

There was a stallion behind the cash register there with a blush on his face seeing all the foals. “Wow, you have a lot of foals, ma’am.”

The stallion continued scanning the items as the princess giggled and waved a hoof. “Oh, thank you…”

The stallion turned to the two toddler pegasi. “Three pegasi and a unicorn. And these two pegasi look like little royal guards I saw earlier.”

They both blushed and slinked behind the mare as she laughed. “Oh, I know! They talk about being royal guards all the time; they're just so adorable. Maybe when they grow up they’ll join the ranks, guards have to be able to stand at attention all day without having accidents.”

Both colts were too embarrassed to say anything as the stallion laughed. “Oh, and I bet your fillies will do some impressive things when they're older. They look kind of like Twilight Sparkle who defeated Nightmare Moon and Fluttershy, that impressive model for Photo Finish from a few weeks ago.”

Celestia laughed as Fluttershy groaned, not wanting to be reminded of her short-lived time being a model while Twilight held her head up. “Yeah, tats wight, I beat Nightmawe Moonie!”

Fluttershy grumbled. “Not by yourself, tough.”

“I know tat! He was just saying I helped!” Twilight stomped about and whined.

The stallion blushed, not hearing the conversation. “Oh, wow, they got fussy fast. Did I say something wrong?”

Celestia shook her head. “Nope, they're just foals, I’ll calm them down,” She scooted them off, placed the fillies in a double-seated stroller she’d just bought and placed the items under the stroller’s basket. “Now, it's time to get your energy out.” Celestia then scooted them off towards the school playground.

The princess watched from afar as the toddler guards ran around the playground, whacking each other with their foam weapons. The two fillies were in the sandbox, trying to build a sandcastle with plastic shovels and buckets.

The toddler guards waddled over, now being quite interested in what the fillies were doing. Silverwing plopped down and asked. "Hey, can we help?"

Fluttershy gave a small nod as she hid her face, being a bit shy as the two toddlers sat down and tried showing the fillies how to make their sandcastles.

Twilight blushed as Braveheart showed her how to mix water and sand. "it's weird having two older brothers. It was crazy enough with one, espicawwy when we competed over everything.”

Fluttershy giggled at the two colts became more excited over the sandcastle. “Ya cute pretending to play royal guards, and I like ya more ten my brudda. He was awways so lazy.”

The colts held their heads up in pride just as Celestia came over and asked, “Hey little ones, do you need to go potty?”

The guards squeaked, seeming to have forgotten, and the fillies burst into fits of giggles as the colts both got up while shouting. “Yeah, we need to go potty!”

Celestia picked the regressed guards up from the sandbox and strapped them into a two-seated stroller, leading the toddlers to Sugarcube Corner since that was the closest location that had a public bathroom.

Celestia knocked on the door as Pinkie Pie opened it and gasped. “Oh my, I haven't seen you in Ponyville before!”

“Yes, my name is Sunny Days, and I just need to let my toddlers use the bathroom if that's ok.” The mare asked with a blush on her face.

The two regressed guards were doing “potty dances,” as Pinkie waved a hoof. “Of course, they can use the bathroom right upstairs!”

Sunny Days nodded and replied. “Thanks, we’ll be quick. Can you do me a favor and watch the younger ones for a few minutes? They aren’t quite ready for potty training just yet.”

Pinkie bounced over and scooped Twilight and Fluttershy onto her back as she chirped. “No problem! It’ll be great practice for when Mrs. Cake has her foals.”

“Ok. Thank you, Pinkie. Come on little ones, let’s get you to the potty.” The mysterious mare escorted the toddlers away upstairs as the energetic pink pony plopped Fluttershy and Twilight into two highchairs and she exclaimed. “Oh, wow, you turned to foals!”

The foals glared at the mares and started to babble angrily at the mare. Pinkie burst out into laughter. “Oh, I know, I probably should’ve warned you two. I thought my ‘Pinkie Sense’ was acting up today, and now I know why,” She then took out two bowls of mush and exclaimed, “Now it's time for Pinkie’s num nums!”

After the feeding, Celestia came down with the colts with a smile on her face. “Oh, thank you, Pinkie Pie! They were probably quite hungry.”

“Oh, it’s no problem, princess.” Pinkie hoofed the foals back to the alicorn in disguise, who blushed at Pinkie, knowing she was Celestia somehow.

Meanwhile, Mrs. Cake had woken up from the commotion and had come down to see what it was all about. Her eyes lit up upon seeing the strange mare and all the foals. “My goodness, you brought quite the family.”

Sunny Days looked up and waved a hoof. “Oh yes, these are all my precious foals.” She nuzzled them all as Mrs. Cake asked. “Are you staying in Ponyville?”

The mare gulped and shook her head. “Oh no, I um...live in Manehatten. I only came to uh get away from the big city for a while.”

Pinkie bounced over. “Oh, that's cool! How do you like it here so far? Also, what's your name again?”

“Oh, it’s...um Sunny Days.” The princess stammered, knowing Pinkie was trying to help, but it also felt odd lying to ponies that had catered to her a few hours ago.

Mrs. Cake came over and replied. “Well, Sunny Days, you and your foals are welcome here anytime you like, please make yourselves at home.”

Sunny Days nodded and continued. “Sure...I'll be back one of these days, but I should get these foals home. They played for a good portion of the day, and I think they're ready for a nap.”

“Well ...I am having a foal soon...maybe you can give me tips…” The mare squealed, and Sunny Days was a bit stunned. “Well, I guess…” She felt really awkward now seeing she was pretending to be a mother with foals.

Mrs. Cake shook her head. “Oh, you don’t have too. I just found out I'm pregnant, and it’ll be awhile before I start raising foals of my own.”

Sunny Days laughed, turning to Pinkie. “I daresay that you have raised a foal already.”

“Hey, I'm not a foal!” Pinkie exclaimed!

Mrs. Cake snickered. “You sure act like one.”

Sunny Days turned to see the sun was setting and sighed. “We better get going...it’s getting late.”

“Of course, please don’t let me keep you here,” Mrs. Cake waved a hoof. “Pinkie, would you mind escorting Sunny Days and her foals?”

“Oh, sure! That’ll be super fun!” Pinkie cheered, plopping the regressed royal guards onto her back and skipping out of Sugarcube Corner as Sunny Days followed along.

As they went towards Fluttershy;s cottage, Twilight and Fluttershy were barely awake as the stroller's motions rocked them to sleep, and the colts were quite exhausted lying across Pinkie Pie’s back as she asked. “So, Celestia, can I be a foal too?!”

The princess’s eyes went wide and asked, “You want to be a foal?!”

“Yeah, it sounds like fun.” Pinkie chirped, looking quite excited.

Celestia laughed. “Sorry, but Philomena won’t have another rebirth for another few years, and this regression is only temporary, luckily.”

“Awww.” Pinkie cooed as she pouted and skipped along and responded. “But you can maybe find some magic to regress ponies, right?”

The princess blushed, “I could look into it…” They then opened the door to the cottage and found something quite surprising. Philomena was holding a bottle of milk to Angel’s mouth, who was suckling it like a foal.

They both squeaked, and Philomena flew off to her perch while the bunny bounced off. Celestia and Pinkie Pie both burst into laughter as they placed the foals down. Pinkie Pie took out some sleeping mats and placed them on the ground, tucking the two colts into bed.

Celestia took the two foals, laid on the couch and placed them next to her breasts. Twilight and Fluttershy were a bit stunned as they placed their mouths over the teats and slowly suckled on them. Fluttershy cooed as she nursed down the warm creamy milk and slowly soaked her padding, making it yellow and swell. Twilight squeaked as the same happened to her.

The fillies both felt embarrassed, but they could barely concentrate as they suckled out Celestia’s milk and drifted off to sleep.

Twilight woke up the next morning in a fresh diaper and was quite surprised as she turned to see both Pinkie Pie and Fluttershy in pampers. Twilight was a bit stunned as her eyes adjusted from her sleep but were relieved to see her friends were full-grown adults now, even if they were both wearing Luna special nighttime diapers. She sighed in relief. “Ok, we're back to normal, more or less…” She gulped as she got up and began to waddle downstairs to see that the two royal guards were in thick diapers too and were asleep on their mats, sucking on their hooves with big dumb smiles on their faces.

Celestia was coming back through the front door and turned to Twilight. “Ah, it looks like you're the first one up.”

Celestia came over, checking Twilight’s padding as the unicorn asked. “So...we turned back to normal during the night?”

“Yes, thankfully, it was fun babying you, Fluttershy and my guards, but I was worried that you would’ve stayed as foals longer….though,...did I do a good job? I never cared for actual foals before.” Celestia whispered, feeling a bit unsure of Twilight’s answer.

Twilight waddled over and nuzzled the princess. “You were an amazing mother! I wish you could have foals of your own.”

Celestia laughed as she nuzzled her student back. “Yes, it would be great, though finding a suitable partner with which to have them would be hard, and adoption would be just as tricky. But I guess, for now, caring for you and your friends are good enough,” She turned to the two royal guards who squeaked upon seeing their padded rumps. Celestia laughed. “Don’t worry, you didn’t use them.”

Silverwing sighed and then asked. “Um, princess...may we remove our padding?”

“Hmm, not yet. Not until after breakfast.” The princess proclaimed as she turned to Twilight. “Wanna help?”

“Sure!” The unicorn shouted and rushed off with Celestia to the kitchen leaving the two padded stallions alone.

Fluttershy was the last to wake up; a bit embarrassed at seeing she was still in her freshly changed pampers as she waddled down the cottage stairs and turned to see Celestia.

Twilight went about serving pancakes and eggs with every pony getting a coffee bottle mixed with the princess’s milk.

Celestia turned her attention to Fluttershy and waved a hoof. “Come on over; there’s plenty of food,” Fluttershy nodded a bit shy, seeing so many ponies in her home as she plopped down in her padding, the two guards instantly went about putting a bib around her neck and placed some food near her. “Oh, thank you...you didn’t have to do that.” Fluttershy whispered.

“No problem.” Both guards exclaimed as they plopped on either side of her.

Celestia giggled. “Awww, they act as your big brothers still.”

Fluttershy blushed and explained. “Yes, well, they are rather nice.”

The guard's cheeks flushed red as Twilight gulped. “So Fluttershy….d...do you like um…”

“Wearing diapers?” The pegasus mare asked as she poked her padding. “Well, it does feel rather nice around my rump.”

Twilight sighed and asked. “Ok...would it be ok if you wore a diaper to the gala? Everyone else is gonna wear one, aside from Rainbow Dash but that’s because she’ll be wearing pull-ups.”

Fluttershy gulped as she whispered, “Actually I...I was thinking about things…” The pegasus mare turned to Celestia. “Princess Celestia, yesterday was one of the most fun days I've ever had, and for the gala, I wish to go to your garden and see all the exotic animals there… But w...would it be ok...if...if I went to the gala..a...as...as….as…”

Celestia blushed and whispered. “You mean, as a foal?”

Fluttershy nodded, hiding her face behind her hooves and the guards stood up; one responded, “If that's the case, we will gladly be her escort.”

“Yes, we shouldn’t leave a helpless foal by herself if that's the case,” Braveheart responded, standing up in his pampers with a puff of foal powder billowing from his leg holes.

Celestia sighed as she pondered the idea. “I guess I can look into Philomena's feathers and see if I can make a compound to regress ponies...but I think I would need to experiment on other ponies…”

Both guards stood up and exclaimed. “We would gladly be your test subjects!”

The princess dawwed, “Oh, you two liked being my little colts, huh?” She gave their pampers a few pats.

Twilight shrugged. “Ok...I mean, if you want to, I guess…”

Pinkie raised a hoof as she bounced on her padded rump. “Oh, I want to be a foal too please!”

Celestia laughed. “Ok, ok...but it’ll take some time to make the regression potion. And your exact ages may vary.”

“Thank you, mo- I mean princess.” Fluttershy squeaked as she continued eating her food.

Celestia sat down with Philomena perched on her shoulder as she pondered how she would make an age regression potion before the gala.
