If you try to force him to do it, he'll be less interested. You know how men/boys can be, it's got to be their idea! My youngest of 3 is in the transition now. His potty seat sits out where he can get to it any time. Sometimes he goes...sometimes not. When he does, me and his older brothers make the goofiest big deal you've ever seen. Unfortunately, I'm more done with buying and dealing with diapers, than he's done using them!
