My ds is 34 months old and has been potty trained since last summer. He now goes on the toilet but I always end up having to help him otherwise he manages to spray wee everywhere! He has a child seat on the toilet. He is now having trouble when he goes to playschool and has had to go back to using potty there. Also - he always takes off trousers and pants otherwise he can't get on the toilet and this isn't helping him at playschool either. Any tips?? Thanks!
