My 3 year old has been fantastic to potty train and we thought he had really good muscles as really seemed to push when doing a wee. Then we noticed that his willy seems to blow up like a balloon when he starts to push and then after a delay the wee comes out. He also complains that his willy is sore sometimes. Anyway I took him to the GP whoh got me to pull the skin back and you could see that there is an excess of skin on the end and the opening is very tight. So we have an appointment with a urologist. Any advice, experience? The thought of my lovely little boy being cut is horrible!
