The baby yawns. Leah yawns, too. The baby's eyes close, and Leah suddenly realizes how comfy she is right now. A nap sounds great...
The woman with the baby in her cart leaves the aisle, but the smell of poop doesn't leave with her. Tina looks around, confused, then her eyes land on Leah. Her teenage stepdaughter is fast asleep in the cart seat. And...smelly.
Tina carefully lifts the skirt of Leah's dress. She gasps. There's a massive load of poop in her underwear, staining it and the dress, to boot! Tina shakes her head. She knew that Leah sometimes wore pads to bed because she was prone to nighttime accidents, but this is something else entirely.
Tina grabs a package of diapers in Leah's size as well as a very cute baby shirt that says "Mommy's Little Poopy-Pants" on it. It will look so adorable on her.
Leah sleeps through Tina cleaning her up, putting the diaper on her, and dressing her in the shirt. Tina opts to not have anything cover the diaper, that way it's easier to tell when she needs a change. Until Tina feels sure that Leah won't mess herself in her sleep, the girl is going to be diapered while sleeping.
Leah doesn't wake up until they're already in the car and almost home. She looks around, confused. She's in a car seat?
"Sorry for the car seat, sweetie, but you look like a baby right now, and I didn't want to be pulled over," Tina says. Leah looks down at herself. "Look, you messed yourself while you were sleeping in the store. Completely ruined your clothes. I had to find something new for you to wear. And some protection, of course. Until you sleep without accidents for a week, I want you sleeping diapered, okay?"
"But-" Leah starts. She stops. It's less embarrassing for Tina to think she had a sleeping accident than to tell her that Leah pooped her pants on purpose because she saw a baby do it. "...Okay."
"Thank you for cooperating," Tina says. Leah grumbles. As does her tummy. She has a sinking feeling that she's not going to have a clean diaper for long.
