What I did was have a few potties around the house for a start,like in front of the TV and in the bathroom. I also put a special packet of smarties on top of the TV so that he could see his prize and everytime he asked for them or even if I'd walk past him watching tv, id tell him that when he did a wee in the potty he could have them. When we'd go for a shower I'd turn on shower and I would sit on the loo and while i was on, i made him sit on the potty too, eventually this was where he did his first "wee" or should i say about 1/2 teaspoon of wee. We made such a fuss for him, giving him high 5's and of coarse his Prize, we also made him call my mum and tell her that "he did a wee in the potty" From then on it happened really quickly, we still did the party thing when he wee'd and he got a funsize smarties for a couple more times until he really got the idea of when to go. Then it was number 2 time......

Good luck anyway
