T.Y.
S., first start off rewarding your son with jelly belly beans or m&ms. One little jelly bean can make the difference.
So when his diaper is off and you tell him that if he sits on the potty, he can get a jelly bean of whatever his favorite color is. Let him know that he does not have to pee, reward him at first for just sitting on the potty with his diaper off. The first time he urinates on the potty make a big deal out of it with hugs and kisses and jelly beans. Be patient and consistent and he will it time become potty trained.
Remember reward him with something he really likes, it doesn't have to be jelly beans or m&ms. Angie
