Silly question: DS, 3yo, has been completely toilet trained during the day for 6 months +. However, he still sits down to wee. When do people teach them to stand up to do it?? I am fine with him sitting down (it's much tidier!) but don't want him to be teased at nursery if sitting isn't really the done thing. As an added complication, unlike the usual reputation of little boys, he hates touching his penis, so will really need encouragement if we are going to teach him to wee standing up...
