HELP!!!!!

OK, so I’m asking for help, especially from the moms of boys (but if your girls went through this then I’ll take that help too!). I think I’m also just soliciting confirmation that my son is normal and that there’s not something wrong with him (as I’ve heard this happened to another boy our old sitter watches as well).

Here’s the problem:
We potty trained my son in October. As you might know, it was a fairly easy process, and once we were done, he was good to go. We went to Disney World for goodness sakes and he did not have one single accident the entire trip!

So fast forward to about 2 weeks ago and all of a sudden he’s started having accidents. At first, it seemed he would have them when he was in the basement and we thought maybe he wasn’t making it all the way upstairs in time (because he would go a little, and then come up and tell us he had to go potty, and then he would go in the potty). But then it started happening at other times…he’d be playing in the family room with us (20 feet from the bathroom) and he do it. And then like last night, we were cuddling in my bed watching a movie (about ½ hour after he had gone potty), and he tells me he has to go. So we run into my bathroom, and he’s already started to go.

I just don’t get it…we haven’t had any of the big things happen that I’ve heard cause kids to revert back (new baby, moving, etc.). And hubby and I have worked really hard making him go more, and we’ve talked to the babysitter about it, and she reminds him to go more as well. We’ve tried everything from punishment to rewards and nothing seems to be working. And my daughter never did anything like this, so this is very new to us.

So tell me all my wise friends, what is going on??? We’re at our wits ends trying to fix this!
