He is nearly 6, and keeps wetting himself - we have tried all the positive encouraging sticker reward charts lots of praise etc but he just seems to be getting worse instead of better. We have told him he will not have any chocolate until he can get to the toilet in time. He has had a sore willy and we have pointed out it is because he wets himself, we have had him checked and he hasn't got a uti. What would you guys do if you think iambu?
