The effort of trying to make it to the door while trying to stop filling her diaper had worn Leah out, despite her failure to achieve either task. Her eyes slowly drifted shut. She slid from her squat into a seat on the floor, then curled up in the fetal position, still sucking her thumb.
In the morning, Rita finished setting the table for breakfast and frowned, wondering where Leah was. She went to Leah's room and pushed open the door. Her eyes widened in surprise at the sight of Leah in a fully packed diaper, curled up on the floor, fast asleep, sucking her thumb.
"Oh, sweetie," Rita sighed. She felt she could connect the dots. Leah clearly had sleepwalked last night. It wasn't safe for anyone to sleepwalk, let alone someone Leah's size, so as Rita carried Leah to get a change, she thought about how to keep Leah from getting hurt in the night.
Leah woke up during the diaper change, seeming confused.
"What- Rita-"
"It's okay, I figured I'd change you," Rita said soothingly. Leah winced.
"Thanks. I, uh, I really went last night, huh?"
"Yes, you did," Rita chuckled. Thankfully, Rita being so casual seemed to soothe Leah. She relaxed and laid back casually for her change. Though she did squirm a bit at the cold wipes. "So, I found you on the floor..."
"Oh. Um..." Leah winced again.
"Don't worry, sleepwalking is nothing to be ashamed of!" Rita reassured. Leah relaxed again. "But given your size and nighttime incontinence, I think some measures should be taken to keep you from getting hurt sleepwalking in the future."
Leah, for her part, was more than willing to go along with what Rita said. It was less embarrassing for her to be thought of as an incontinent sleepwalker than to tell her what had really happened last night. If that meant going with whatever Rita thought would "keep her safe", so be it.
"Okay. What did you have in mind?" Leah asked. Rita smiled at her as she taped on Leah's fresh morning diaper.
"Well, I was thinking..."
