M.B.
I also wet the bed for many years... I don't know when I outgrew it. I remember dreaming about going to the toilet, but would start to pee, and realize the toilet lid was down, and I got wet, and that was what woke me up to find out that I had wet the bed.
Unfortunately, there weren't goodnights or similar items.... I just had a plastic mattress cover under my sheet......
I remember going on sleep-overs and having the mother put a plastic bag under the sheet where I would be sleeping.... now that was humiliating!
Anyway, I am glad you have the goodnights for her..... I don't think I would get her the "cute" type, but something as plain as possible.
Now... why did she wet the bed more frequently this week? What happens when she does wet at night? Does she get up and take care of it herself, or does she sleep through it in the wet goodnights?
I wonder if they are making it too "easy" for her.... she doesn't feel it, so she doesn't waike when she wets.
I wonder if you put a regular pair of underwear on her first, then the goodnights.... she might wake when she wets, since she has the wet material next to her skin. Would that help "train" her to feel when she is wet? I don't really know... I'm just reaching for a solution here......
