Oh, one other thing, he no longer has a potty pad in the ex-pen. It was there in hope that he would use it if he was going to have an indoor accident. Well, he never once managed to hit the pad, so since I do not want him going inside anyway, I figured it was defeating the purpose. I never did put him on that particular pad to go, but it is the same as what is in the potty box in the garage, so I thought maybe he'd use it, but it is probably best that it is gone now. It is just so hard to know what is right when you start out with your first.
