It sounds like some tough love is due here.He is at the age where he knows right from wrong. He shouldn't be wetting his pull-up then taking it off. What are you doing as far as disciplinary action toward him after he's wet himself? I really hope he's not going poop in his pull-up too. Have you gone shopping with him and let him pick out some cool undies  to wear (but only if he agrees to go potty when he feels like he needs to)? Are you vigilant with asking him if he needs to go potty. Every 45 minutes to an hour make him go to the bathroom. Interrupt his playtime. Take away toys and sweet treats until he gets it right. He is far to old (in my opinion) to be in pull-ups. Don't offer a treat for going potty. Or praise even, take that privilege away. But he needs to understand that because he is not using the bathroom where he needs to that there will be disciplinary actions. Let us know how it goes. By the way is he your first? I say that because once a child starts walking they be introduced to the idea and notion of going potty on the pot. 12-18 months is a good time to start introducing it. It does take awhile. Part of the problem could be that he had the capacity to "get" it long before you started training him. We underestimate how smart our little ones are. Please don't take offense, it's not a judement call on your parenting.Just trying to break it down so I can understand. Also, is he in a toddler bed? If so, have him remove the sheets and take themto the laundry room. It sounds like a lot, but my daughter has just turned 4 and she's been taking her dirty clothes to the laundry room since she was 2 and a half. He can handle something like that.He needs to understand the frustration and work it causes you. Once again, let us know how it goes.
