as long as they grow out of it. It is funny how many things that we take for granted are brand new to young children. My kids were extremely fascinated watching (their own) poop spiral down the toilet for the first time. I suppose we all study and try just about EVERYTHING at least once before we grow up, even the gross stuff. Gotta remember to keep the electrical outlets covered. If they are anything like me, though, they won't rest until somebody gets really zapped.
