My DS is nearly 4; he starts school in September and we started potty training 14 months ago. At first he was dry all the time; never poo-ed except in potty, even went some nights dry. For the last 6-8 months he's wet himself almost every day, sometimes 3-4 times a day. It's only a little, but enough to leak through his clothes. He sometimes goes several weeks without being wet, so I know he can do it. He has a tell-tail jiggle when he needs to go, but when you ask him directly if he needs a wee, he says no. Then he wets himself a few minutes later. We've done reward charts, encouragement, treats etc. I'm at the end of my tether and getting very nervous about him starting school. As it is he'll only be just 4 when he starts and if he's not potty trained as well, I'm very anxious about him coping. I'm also getting cross when it happens, and although I try my hardest not to let him see this, I'm sure my frustration must show. What can I do? I need some help here, and soon!
