In my opinion starting and stopping isnt a good thing. With all 3 of mine I commited to doing it and stuck with it. I found naked or bottomless worked MUCH better than training pants. They seem ( or at least my boys did) to remember better naked. I would keep trying but naked. Like the pp said make sure he goes in the bathroom to get cleaned up. Give him a wipe and have him wipe the pee off himself but be positive and say "next time we can make the pee go in the potty and not on your undies"

Everything happens for a reason, sometimes the reason is you're stupid and make bad decisions
