I have a 2 1/2 year old boy. He is fully potty trained and its wonderful. I made a huge deal out of it and would play games. One time we put a bowl of gold fish crackers in the bathroom and we would toss one in the toilet. I would laugh and say haha lets peepee on the fish and watch him swim around. Then we would laugh & laugh about it after he did it. If he had an accident we would act silly about it, laugh & then start over. He picked out his favorite underwear. I never rushed or got upset if he messed up! It will happen over nite just have patients for the little guy and love & praise him when he makes you proud.
Good luck!!!
