Hi Pamperslover, text me soon. Do you think that your nephew is really loosing his bladder and bowel control or do you think he's playing along? What I would do is to check his diaper, like a diaper check. Like wait for a few minutes and if he doesn't say anything just pull the back of his diaper. Maybe I should send another one so he can be more babyish.
I can text you, just give me your number in the private messager
