Leah didn't need any extra help in becoming a baby on her own, not even the laxative she was unaware of, really. She was already on the path after her "acting exercise". But now she found the distance between her and babyhood getting shorter. And Rita's treatment wasn't helping.
Leah's breakfast bowel movement turned into a blowout, dirtying her clothes and even getting on the chair she was sitting on. Rita insisted she wear a diaper cover and no bottoms, to avoid getting poop on any other clothes or furniture. Unfortunately, the laxative was still wreaking havoc on Leah's body, and less than an hour after her blowout, Leah had another one. While sitting on Rita's couch.
Rita's patience was gone at that point. She cleaned and changed Leah, but kept her in the bathroom while she "got something ready". After a few minutes, Rita came back and carried Leah into the living room, where a playpen was waiting.
"Look, you can't keep getting your waste everywhere," Rita said firmly. "This is the third time. I checked your bed, and your mess got onto it during the night." At Leah's tearful expression, Rita softened her tone. "It's not your fault, Tina just brought the wrong kind of diapers for you. I've ordered some thicker ones, but until they get here, you'll have to be in the pen. Sorry, but I have to protect my furniture."
"I get it," Leah muttered, slumping helplessly in the playpen. She felt warmth spread through her diaper as she peed again. She was startled by a sippy cup being shoved in her face.
"I don't want you to get dehydrated," Rita said. Leah reluctantly took it. She took a sip. It was apple juice.
"I don't need a sippy cup. I can drink from a regular cup," Leah pointed out. Rita patted her head.
"I know. But once you're out of the pen, you'll be using mess-proof, spill-proof things to keep my belongings clean."
"Why'd you agree to babysit if you were worried about cleanliness?" Leah snapped. The response made her cringe.
"I thought teenagers were a bit more capable than you're being. I guess I was wrong." With that, Rita walked away. Thirsty and ashamed, Leah shoved the sippy cup in her mouth and guzzled the contents.
"Want more juice?" Rita asked.
"Yes, please," Leah mumbled. Rita took her cup away to refill it. Leah's mouth suddenly felt very empty. Her thumb crept towards her mouth, but she managed to pull away at the last moment. A surge of pride filled her, along with embarrassment that not sucking her thumb was now something she felt proud of.
A rumble rippled through her tummy. Leah let out a little fart, along with some mushy poop. Her self-control failed. She shoved her thumb into her mouth, sucking on it desperately for comfort until Rita returned with her sippy cup of juice.
"Making poopy again? Let me know when you're done and I'll change you," Rita said. She handed over the sippy cup. Leah replaced her thumb with the cup, gulping down the drink as she felt the seat of her diaper expand, filling with more and more poop.
Leah knew what she looked like. A real baby in a playpen, using a diaper and drinking from a sippy cup. She couldn't keep this up, she had to do something, or she'd basically be ready to sign up for daycare by tomorrow!
