Cutie Mark Cry Babies

Sweetie Belle awoke the next morning to the sound of birds chirping outside her bedroom window.

As she began to stir awake, her eyes coming into focus, she became aware of her new surroundings.

All around her bed were bars that were just high enough that her chin barely touched the top bar.

The bed where she’d gone to sleep in the night prior was now a crib, with just a single pillow and blanket.

Through the bars, she could see her room now looked like a nursery.

Where her trunk once sat was now a rocking chair, and below it, a few toys on a rug that were designed for foals. A ring stack game, a rattle, little pop up toys, and a few others designed to stimulate a simple minded baby.

Her dresser was also gone, a changing table now in its place.

Sweetie could already see a drawer was open and some diapers sticking out.

She froze.

She looked down at herself.

Her bottom half was still covered by her blanket.

She could feel something bulky wrapped around her waist, and even worse, it felt damp.

No…no please not that….

She didn’t want to look, but had to confirm her worst fears.

Upon pulling back her blanket, her suspicions were confirmed.

Wrapped around her waist was a thick and poofy disposable diaper, complete with a yellow stain right on the front.

Sweetie couldn’t believe it. She was now a complete baby in the eyes of everypony.

The realization was overwhelming for her and she began to cry.

She wasn’t entirely sure why she was crying, her natural instinct previously would’ve been to curse or perhaps punch something, but she couldn’t seem to control herself as her emotions caused her to wail and cry like the baby she knew she now was.

A few minutes later, she heard a door open.

“Sweetie? Oh dear what’s wrong? Come here.”

Sweetie felt herself being picked up and held, cradled in somepony’s arms.

The effect it had on her was immediate, and she began to calm down, her crying turning to sniffles as she was held and had a hoof rubbed against her back.

She felt a lot better knowing somepony was there to comfort her.

Upon being shifted in the pony’s arms, she saw it was her big sister Rarity, beaming up at her with a smile.

“That’s right baby sister. There’s no need to be upset. Let’s get you ready for the day shall we?” She said as she carried Sweetie out of her crib and over onto the changing table.

Sweetie began to feel upset again, starting to fuss at the embarrassment of her big sister changing her, but before she got started she felt something slipped into her mouth.

Without even thinking, she began to suckle on it, the object bobbing in her mouth. Like magic, she felt calm again, enjoying the sensation.

“None of that now. Let’s get you changed.” Said Rarity as she got to work, making a quick job of stripping Sweetie’s wet diaper off her and wiping her crotch and butt down with a baby wipe disposing of both in a diaper pail by the table.

She then got out a new diaper, opening it up and laying Sweetie’s tushy on top of it and sprinkling her whole area with foal powder. She then fastened the new diaper tightly around her little sister’s waist, picking her back up and giving her diapered bottom a pat.

“All better. Let’s get you some breakfast and then it’s off to your play date.” Said Rarity as she carried Sweetie downstairs.

Sweetie tired to organize her thoughts as her sister brought her downstairs and sat her in a highchair.

It was so hard to focus on things now for some reason without getting worked up or consumed.

She realized she must’ve fallen asleep last night and missed the plan. She hoped Scootaloo and Apple Bloom had gone on without her and were speaking to the Princesses right now to undo this mess, but she knew this was unlikely.

They would’ve made it to Canterlot long before now, and the fact that things now only seemed to have gotten worse for her likely meant they were in the same boat.

Breakfast consisted of a sweet tasting mush that although Sweetie had found the idea of repulsing, had actually quite enjoyed, even if a good bit ended up on her bib and muzzle.

She especially found herself giggling at her sister making airplane noises as she maneuvered the spoon into her mouth, but each time after she swallowed was upset that she found such a foalish thing amusing.

She was then feed a bottle, an activity she thought would be difficult but was actually quite easy as she suckled the formula from the bottle’s nipple.

She found it to be a familiar action, like she’d done it a million times.

After she’d finished and been burped, Rarity had stuck her on her back and headed out the door, grabbing what looked to be a diaper bag and slipping what Sweetie now realized was a pacifier back into her muzzle.

The two of them were now headed through the streets of Ponyville, headed Celestia knows where.

She hoped it was to see her friends. With any luck maybe they could still figure out a way to fix things, even if everypony thought they were now foals.

Sweetie spent the trip on her sister’s back trying to spit her pacifier out, but found herself unable to.

Any time she tried she couldn’t help but enjoy the satisfying sensation of the soother bobbing in her mouth.

She noticed ponies they passed would occasionally coo at her and say how adorable she looked.

This made her blush deep red with embarrassment, but made her want to giggle at how silly they were talking.

Before long she found that Rarity was taking her to Sweet Apple Acres and in the direction of the clubhouse.

She could see Applejack and Scootaloo’s Aunts were outside, appearing to have a picnic.

“Hey there Rarity! Glad you could make it. Go ahead and drop Sweetie in the play room with her friends.” Said Applejack.

Rarity carried her up the tree house stairs and up to the entrance.

A baby gate was attached to the doorway, allowing the door to remain open and allow the three mares outside to hear if anything was wrong.

Rarity sat Sweetie down and the floor, placing a bottle next to her in case she got thirsty.

“Play nice with your friends sweetie while sissy has brunch with her friends!” Said Rarity, turning away and walking back down to Applejack and Aunt Holiday and Lofty.

Looking around, Sweetie could see the tree house was now much different.

The room looked much like how her room had looked.

Baby toys were strewn around the floor. A changing table was against one wall and three large cribs were nearby.

Baby pictures of Sweetie Belle and her friends playing together adorned the walls, with them playing, taking baths, and doing other foalish things together.

On an area rug not too far from her, she saw Apple Bloom and Scootaloo, both sitting in their own diapers.

It appeared they may’ve forgotten about the plan too.

Sweetie walked over to them, nuking on her pacifier as she went. She hardly realized it was in her mouth anymore.

“Sweetie Belle! Are you ok?” Asked Scootaloo.

Sweetie tried to answer, but her pacifier was in the way.

“Try this.” Said Apple Bloom, leaning over and pulling the pacifier out of her mouth.

With the paci gone, Sweetie found she was able to talk again.

“Thanks Apple Bloom. I’m fine. Apart from, you know this.” She said gesturing at her diaper.

“I know. We woke up wearing ours too. Don’t bother try’in to take it off though. I wasted about ‘n hour this morn’in try’in and nothing worked.” Said Apple Bloom.

“I take it none of you managed to stay awake last night either huh?” Asked Sweetie Belle.

“Nah. My Aunts put me to bed and read me to sleep. Don’t even remember them turning out the light.” Said Scootaloo.

“Same happened to me too. Never even saw the sun go down.” Said Apple Bloom.

“What’re we gonna do? The magic seems to be affecting us now. We can’t even take these stupid diapers off!” Said Sweetie, hitting it with her hoof.

“We could try sneaking out again tonight.” Said Scootaloo.

“Even if we manage to stay up late enough we wouldn’t be able to get out of our cribs. Plus I tried talk’in to my family this morning and they couldn’t understand me. I doubt the Princesses would be able to either.” Said Apple Bloom.

“Well we gotta do something! I don’t wanna be a baby!” Scootaloo yelled.

“And you think I do?” Apple Bloom yelled back.

Sweetie watched as her friends argued back and forth. It looked like they were out of options. She hung her head and began to tear up, thinking of all the fun things her and her friends would probably never get to do again.

Out of the corner of her eye, she saw her reflection in the mirror on the wall.

At least, it looked like her reflection.

While her reflection did show her as a baby in the mirror, her mirror self appeared to be smiling, and motioning her to come closer with her hoof.

Curious, Sweetie walked over to the mirror, watching as her foalish reflection peaked its head out.

Sweetie just stared, astonished at what she saw.

“Why so sad little one?” Her reflection asked.

“I’m not supposed to be little! I’m supposed to be a big mare!” Said Sweetie.

“Aw being little isn’t so bad. No cares, no worries. All you have to do is have fun!” Her reflection beamed.

Sweetie thought about this. Her reflection did have a point. Foals didn’t have to worry about anything. Big ponies took care of everything for them. Even so though, she still didn’t want to be one.

“But I’m in a diaper!” Sweetie whined.

“Those are great too! You don’t have to stop playing to go potty. You just keep playing! Here! Let me show you!”

Before Sweetie could react her reflection reached out and touched her diaper. In an instant, she could feel her diaper getting heavier.

Looking down she saw her diaper front yellowing as she wet herself. From behind, her rear was turning brown as she messed herself.

Although Sweetie wanted to feel gross and disgusted with herself, she found instead she was feeling giddy, and more so by the second.

The warm confines of her diaper hugged her bottom and crotch as they clung to her body like a warm hug.

Her head was also starting to feel warm and fuzzy, like it had been covered in a warm blanket.

Her mind was beginning to change, forgetting everything she knew about being a big mare and only focusing on being a proper baby filly.

Suddenly being a foal didn’t seem so bad. In fact, it was beginning to sound like a great idea!

Sweetie began to drool and giggle at her reflection as she finished using her diaper.

She knew she felt sad a minute ago, but couldn’t care to remember why! She was just a little foal, and foals just focused on being happy!

“See? Isn’t it better being a foal then a boring old big mare?” Her reflection said.

Sweetie nodded dumbly, shifting in her seat to feel her warm mess shift and squish.

“Now go play with your other baby friends Sweetie. Here’s a toy they’ll really like!” Her reflection said as it placed a red rubber ball with stars on it in Sweetie’s hooves before disappearing back into the mirror.

Sweetie looked down at the ball. It felt smooth and squishy. She wanted to show it to her friends!

She turned and rolled it over in their direction.

As Scootaloo and Apple Bloom continued to argue, they noticed a ball roll in between them.

Their eyes locked on it, unable to focus on anything else.

Scootaloo walked over and sat down in front it.

She wasn’t sure why the toy had captured her attention, but she felt an overwhelming need to examine it further.

She reached down and touched the ball with her hoof.

In response, she felt a warm feeling begin to spread from her hoof throughout her body, making her feel warm and fuzzy.

Suddenly she began to feel confused.

What had she been doing? She and Apple Bloom had been talking about something. But what?

This round thing in front of her was pretty! What was it called?

Her mind began to simplify, focusing only on here and now. The pretty thing made her happy! Her friends were here and they made her happy! She began to smile, giggling as drool began to poor down her chin and onto her chest.

She felt a warmness spread around her crotch as she wet her diaper without warning. That was normal though. She liked how her warm diaper made her feel!

It made her feel safe and comfy!

She brought her hoof off the ball and stuck it in her mouth, sucking on it as she looked up at her friend Apple Bloom.

Apple Bloom was now walking forward and sat down opposite Scootaloo.

Like her she couldn’t seem to keep her eyes off the red orb. Her only thought was to reach out and touch it, even though a small part of her was telling her to stay away.

An empty eyed Scootaloo noticed Apple Bloom in front of her.

“Bwa!” She said, taping the ball with her hoof and rolling it toward her friend.

Apple Bloom instinctively put a hoof forward to stop the sphere coming at her, and all of a sudden everything seemed to fall into place.

Things in her mind blew past her subconscious at a break neck speed. Calculus, times tables, history, reading, writing, counting, talking, potty training, as these things registered in her mind she realized she couldn’t recall what any of them were.

She knew she remembered them before, but now they seemed entirely new.

Her mind felt like it was filling with hot air. It tingled and made her feel funny.

She began to giggle, drool running down her chin as her mind finished clearing out all its pesky big pony thoughts.

She looked down at the ball in front of her.

It was pretty!

She babbled at it, pressing her hoof against it.

Scootaloo babbled at her friend, happy to see she liked the toy she’d shared with her.

Meanwhile Sweetie had come over, happy to see her friends partaking with the reflection’s gift.

The three spent the next hour like this, babbling and playing like little foals do, sticking things in their mouth and batting at them with their hooves.

As they played Scootaloo soon joined Sweetie in the droopy diapee department, stopping and bending down for a rattle. She grunted as she pushed a nice load into her awaiting diaper. She let out a sigh, enjoying not feeling so full and uncomfortable, grabbing her rattle and plopping down on her messy seat with a squish. Her messy bottom was the perfect place to rest her plot.

Apple Bloom didn’t last much longer, wetting her diaper thoroughly in the front and only a few minutes later, finding her tummy cramping and leaving a load of horse apples in her diaper. Her foalish mind didn’t mind it one bit, if anything liking the warm feeling she now felt her diaper giving her as she continued to play.

After a while their caregivers came up to check on them, finding the three babies in need of a change and setting to work, laying them down on changing mats and cleaning their mare bits with practiced care before powdering and diapering the three little foals.

All the while above them, invisible to anypony, was Discord, laughing manically as he enjoyed a bowel of popcorn.

Oh how he had enjoyed seeing the CMCs struggle with becoming younger and younger in the eyes of everpony in Ponyville.

It had been just the sort of little chaos he’d needed to entertain his bored mind.

He could barely contain himself as he saw them resist his magic and fall into the warm embrace of foalish ignorance they were now experiencing.

The uncomfortable looks on Applejack, Rarity, and Aunt Holiday’s faces as they changed their charges messy diapers was priceless too. In fact…

The three had just placed the CMC’s in their cribs for naptime.

“Whew wee! They sure did a number on those diapers. Hopefully they won’t have gone too much when we get them up in a few hours.” Said Applejack as her and her fellow grownups left to go back to their picnic, Rarity and Aunt Holiday nodding in hopeful agreement.

Discord couldn’t help himself.

He shot bolts of magic at the three crusaders, causing the three sleepy big foals to suddenly start squirming in their cribs before their diapers began to fill once more with mess, the magic causing their diapers to fill to cartoonish proportions, looking as if they were wearing beach balls around their waists.

As the three fillies finished and began to drift off to sleep, Discord burst into wild laughter. He couldn’t wait to see them try and change those dirty diapers!

He wasn’t sure how long he was going to keep the crusaders this way. Probably until he got bored with seeing them humiliate themselves or torture their older sisters and Aunts with gross messes.

He’d make sure they all remembered nothing of this. As far as anypony would remember, the Crusaders were just away on a vacation, and had come back feeling refreshed.

But until then, he was going to enjoy seeing what mischief he could get up to with the Cutie Mark Crybabies.
