Dear Beth I would make sure he only puts on the nappy only when he is just going to get into bed! as if he has no problems with night time wetting then obviously it is making him be a bit lazy ie his way of thinking!(oh what the heck I got a nappy on I cant be bothered to go to the toilet ill just wet so what!.) and so by ensuring that he takes it off immediately he gets up as well and make sure he washes as in school he can be ridiculed for smelling !all other times make sure he doesnt have one on except immediately before getting into bed! hope this is of help!
