S.E.
I found training underwear helpful. It keeps that little bit of pee as they realize they are going from leaking all over the place, but wont help full blown accidents. Saves washing pants. Pull ups are not motivating. They are too much like diapers. Buy about 12 or so. Gerber makes them and they can be found near onsies and cloth diapers at Target and Walmart. If you have to, put training underwear on then a pull up if you need to go out of the house and he isn't completely trained. That way he feels the wet and is uncomfortable if he does pee. The best thing I did was let my son go totally naked from the waist down. He was so much more aware that he didn't have a diaper on.
