We have tried everything to assist with potty training. The challenge with this is that when you are first teaching your son to use the potty, it is best for them to sit down to understand both pee pee and poo poo. We used this and he loves it, but he refuses to sit on the potty. We have resorted to bribes and taken Peter Potty away in order to get him to sit down. However once he understands the sensation for each pee pee and poo poo, then I'm sure we will bring this back out again. The other challenge we had is that he keeps going in and holding the water button down until it is empty and we spend a lot of time dumping the water and refilling it so that it can be in a ready status for him to go to the potty when needed.
