I have posted this here instead of the TT section, as I think it more behavioural than anything. Jack will not keep a nappy on, and if he wears undies will wee or poo in them. He has been doing this for a couple of weeks, and today it has escalated. He keeps taking his DRY nappy off to wee or poo on the floor. He knows how to go to the toilet by himself but just isn't. We even put his nappy and cover on backwards to make them harder to get off - he got them off more easily than we could put them on LOL!! He said he wanted to wear undies so I put him in undies and despite using the toilet twice in a short space of time, still managed to wet his pants. Any ideas??
