Frustration....

So CJ seems to be really enjoying school and wanting to go there, in fact he gets upset when I leave him at day care now! However, he has also started having potty accidents again. I don't know if it is because he is reacting to the changes (even though he appears to like them), or if he's too involved in what he's doing at school that he forgets to go (because at day care they have bathroom routine, in that they are all sent to the bathroom at different times throughout the day so he's reminded to go)....or what is going on.....however, it is a little frustrating in that he was doing so well and now seems to be regressing! AGHHHH!!!!
