A few weeks ago, when Leah realized her occasional nighttime accidents were bleeding into the daytime, becoming a pattern instead of a fluke, she did some research. On an incognito browser, of course.
Something she came across multiple times was the idea of re-potty training. Putting a child back in diapers exclusively, then, once their potty training was gone, starting to teach potty training again. The forums online vouched so strongly for this method that Leah felt it was the way to go. Sure, the people online were using the method on very young children, but she felt she could make it work.
But if she wanted to do that, she would need to tell Tina not just the plan but also about her accidents. So Leah didn't. Now, however, was the perfect time for Leah to put her plan into action. As much as it disgusts her, Leah decides she will forgive the toilet completely during her time with Rita, wearing diapers regardless of location and using them exclusively.
When they walk into Rita's very nice house (she is apparently quite wealthy), Tina shows Rita how to change Leah's diaper. Just in case. Tina then chats with Rita while Leah goes to get her stuff from the car. Outside, Leah feels a slight pressure in her bladder. She squats there in the driveway, tinkling just a little bit, not enough to make her diaper damp, let alone yellow. It was scarily easy to do. Clearly, her potty training is even worse than she thought.
After Leah is settled in, Tina says her goodbyes and leaves. Rita orders pizza for dinner and she and Leah watch a movie on Rita's very nice TV. At bedtime, Rita reminds Leah to use the bathroom before she settles in, to reduce the risk of accidents during the night. Leah nods, but doesn't do so.
Leah climbs into bed, her diaper fresh after her shower. But it won't stay that way for long.
The next day, Leah waddles to the bathroom in a soaking wet diaper, ready to change herself. But she still needs to go, so before she changes her diaper, she squats right next to the toilet and pees even more.
"Uh, Leah?" Rita's voice says. Leah's heart sinks. She forgot to close the bathroom door behind her! Hopefully, Rita doesn't get suspicious of her using a diaper right next to a toilet.
