Potty Time?

Brody has taken to hiding behind chairs, under tables, or wherever he feels invisible in order to "do his business". Okay, this means he's ready for the potty, right? I mean, he understands that it is no longer alright to stand in the middle of the room and grunt while people watch. But when I try to convince him to sit on the toilet, he gets so upset! He'll sit on it and read a book when he doesn't have to go, but if I catch him heading for the back of the chair and try to take him into the bathroom, he yells "No, Mama!" So, at the advice of every "expert" out there, I am letting him decide when he's ready to use the potty like a big boy. Heaven forbid I force the issue and he spend the rest of his life in thearpy! ;)
