I Don't Need This!

Josey has slowly been regressing back to a non-toilet trained state over the past month or so. He went quite a long time with no accidents at all, then he'd pee his pants once in a while, then he was peeing his pants about once a day, then the past week or so he's been peeing in his pants more than he has been going in the toilet. To top it all off, this morning he pooped in his pants (fortunately he was still wearing his overnight pull-up so clean up was easy). This is really the last thing I want to be dealing with right now with the move coming up, especially since he really doesn't care that it's happening. He'll even tell you he doesn't have to go, then pee his pants 30 seconds later. We're torn between rewarding him for not having any accidents all day or punishing him for having one. Right now he's not even close to being accident-free so we've been giving him timeouts every time he does it. I don't know whether this is a reaction to being stuck inside all the time, or to the move, but it's driving me insane and I want it to stop!
