Evan met Chloe in one of the empty hallways before school started. The place was barely recognizable as a high school anymore. Only a few teens were even wearing pull-ups, the vast majority had thick, crinkling diapers taped around their waists. Clothing consisted mostly of sleepers and t-shirts, a couple teens weren’t even wearing anything aside from their diapers. A couple still had cell phones or computers, but those objects seemed to quickly turn into stuffed animals and other baby toys in the new reality.

As for Evan, his upper half was that of a teenager, with his headphones around his neck, but the only thing he had on below his waist was a thick, disposable diaper. Chloe had the opposite problem as him. Her hair was in pigtails and she had a pacifier in her mouth, except the rest of her was dressed like a normal 18 year old, though she did have a pull-up on under her jeans.

“Sidney’s managed to do a lot of damage.” Chloe muttered around her pacifier “A lot of students are permanent babies.”

“I’ve noticed.” Evan said “Looks like most of the school is a full-time nursery too.”

“You know I was thinking, shouldn’t we be able to change it back? I mean we hypothetically have some control over the two realities too don’t we?”

“We do, but I think it’s a lot easier to change things to the baby reality than it is to change them back. I turned a cup into a baby bottle in 20 seconds last night but it took me 5 minutes and a lot of focus to just make it a sippy cup.”

Chloe sighed “Well, it looks like we’re about halfway in between the two realities. My Mom fed me cereal this morning but she used… um, her milk.”

“Same here.” Evan said “I mean, not with the milk, but I, er, mess myself but I can still control peeing.”

He sniffed.

“Speaking of which, what’s that smell?” Evan said, fanning the air “I thought there weren’t any babies around here.”

“Um…” Chloe glanced at his diaper. Evan looked down.

“No way.” He pushed a hand into the seat of his diaper “Come on, this is the third time this morning that I’ve needed a diaper change! Can you help me here?”

It took Chloe a moment to realize he was asking her to change him.

“Er, can’t you just do it yourself?” Chloe asked. Evan blushed.

“I, uh, don’t know how to take my diaper off.” He said

“Um, I don’t really want to…” Chloe said

“Come on, my Mommy does it all the time! How hard can it be?”

“Evan…” Chloe said

“What?” Evan looked at her curiously. She could see that he didn’t see any problem with asking for a diaper change. She knew he’d be another baby soon too.

“Nothing. See you later.”

“See you.”

Evan was surprised to see Mia and Sidney in his first class, but then realized that if Sidney could change reality, changing who was in what class couldn’t be that hard. He toddled over to them.

“Hi!” He said cheerfully “Wanna pway?”

“Yeah!” Mia said happily

“Mmm…” Sidney was focused on Evan’s headphones and t-shirt. They shriveled out of existence and a pacifier appeared in Evan’s mouth. She glanced at his diaper and seemed satisfied that it was already messy.

“Sidney!” Mia said

“Huh?”

“We’s gonna pway house! Evan’s baby!”

“Ga ga goo!” Evan said. Even though he was playing pretend, it wasn’t too far off from how he would usually act.

After the loss of Evan, Chloe braced herself for Sidney to come and regress her too. It never came though. Maybe Sidney just didn’t see her as a threat, maybe she forgot about her, Chloe didn’t know. Either way, within a day Chloe found herself completely immersed in the new reality.

Though she was still potty trained, her mother changed her into a thick diaper that night. The packages of pull-ups in her room changed into diapers. The first few times, Chloe’s mother still let her use the potty when she asked to go, but after a few more days she just laughed at the idea that an eighteen year old could use the potty. Chloe couldn’t use the toilet without help, her hands were far too uncoordinated to get her diaper off. She held it for as long as she could, but her mother decided that she was constipated and gave her a laxative. Chloe whimpered as she filled her diaper like a baby.

Chloe could feel her brain atrophying from sheer disuse. Intelligent conversation was impossible since everyone perceived her words as little more than baby talk. The best Chloe could get was a game of peek-a-boo. She began peeing and pooping in her diapers in an effort to make something, anything, interesting happen in her life of endless diaper changes, bottle feedings and naps.

It wasn’t long before pooping became the high point of Chloe’s day. She got so excited whenever she felt her stomach rumble, letting her know that soon her bowels were going to be full. She would just start pushing, trying to get it out into her diaper as soon as possible. Once she was messy she would bounce and squish her diaper as long as she could before her mother would come and comment what a stinky baby she was before changing her.

Despite being reduced to a diaper dependent infant, she still did her best to keep her intelligence. She would scribble calculus problems with crayons to try to keep herself thinking like an adult but as soon as the paper left her hands they always turned into childish doodles. Her mother showered praise on her for her artwork and would tape them to the fridge, which made Chloe feel proud. Eventually she just drew pictures. What was the point of writing numbers that even she didn’t really understand anyways?

One day, three months later at daycare, Chloe was sitting on the floor in just her diaper chewing on a teething ring, expected of someone her age. She still had fleeting thoughts about college and being an adult, but even to her they were little more than a fantasy.

Across the room, Sidney was sitting on the floor, playing with dolls. She wasn’t really into it though. She’d discovered that it was actually kind of boring being the best at everything. Sidney got showered with a near endless stream of praise from adults for getting into pull-ups so quickly and walking and talking like an adult. At first it had been great, but it was starting to get a little old. She had accelerated her own growth so much that she was almost a year ahead of her classmates. They wouldn’t be able to walk for another month or two, potty training wasn’t even on their radar. No one wanted to play with her because she was too mature.

Suddenly an idea popped into Sidney’s mind. She remembered changing reality once or twice from a couple months ago. Maybe she could do that? Change reality so she had a friend?

She looked around the room. She recognized Chloe as a familiar face, though she couldn’t say why. It didn’t matter to her though, she got up and toddled over.

“Big giwl!” She said, pointing at Chloe. Nothing happened. Chloe looked up at her curiously.

“Big giwl!” Sidney said again. She vaguely realized that the new reality had hardened in place, it was almost impossible to change anymore. Unless…

Sidney felt her butt. Pull-ups were nice, but honestly she preferred diapers. Besides, she could go through potty training a third time.

“Big giwl!”

This time she pointed at herself and then Chloe to transfer a little of her reality. Sidney’s butt crinkled and puffed out as she returned to diapers in one last reality shift. Chloe watched in amazement.

“Wow!” She said. She pushed herself onto her feet to get a better look at Sidney’s diaper. Then she gasped, realizing what she was doing.

“I walk!” She said

Sidney grinned. It had worked! Her knees bent slightly and her stomach rumbled. She snickered as she made a mess. She definitely wasn’t potty trained anymore.

Chloe saw what she was doing and mimicked her, squatting and pushing a load into her own diaper.

“Oopsie, went poopy!” Sidney said

Chloe grabbed her and hugged her tightly.

“Tank you!”

She understood what Sidney had done for her. Sidney grinned.

“Wet’s be fwiends!”

“Bestest fwiends!” Chloe agreed

They turned to play but just then they felt their diapers be pulled back. They didn’t react, they were used to diaper checks.

“Looks like both of you stinkers need a clean diaper!” Mr. Tyler declared, looking from one diaper to the other. The girls giggled.

“I didn’t poopy!” Chloe said

“I didn’t go poopy either!” Sidney added

Mr. Tyler rolled his eyes “Then we’re just going to need to change those clean diapers. Come along now, onto the changing mats.”

Chloe and Sidney held hands and toddled together to get their stinky diapers changed.
