Our 6 year old frequently wets and soils himself, even when at home and we don't know what we can do to curb the behaviour. His excuses are he is too busy playing, doesn't like using the toilet, doesn't want to use the toilet, too scared to ask to use toilet (he doesn't need to when at home)....at school he is reluctant to use the toilet, at home we're always suggesting he uses the toilet, he says he doesn't need to and then his trousers are wet. We don't know what to do, seem to have tried everything from encouraging him to threatening him and still no progress. Any ideas on how to deal with this?
