I bought this for my son, who is now two, for christmas '05.His rear fits on it snugly and the guard on the front cuts into his legs so I have to take it off. It totaly defeats the purpose of the guard 'cause we can't use it.The music goes off everytime he moves...not just when he goes potty, so he just thinks it is a fun toy instead of a potty chair and would rather play with it then sit on it. Not worth the money in my opinion...I was very disapointed...looking for something different.
