C.B.
I tried potty training my 2 year old son and he did the same thing. He wanted to, but when it came down to it, he was NOT interested. I am going to try again when he is closer to 3. I think boys are a lot slower at that sort of thing. When he is ready, i am going to use the "potty training in a day" book. I've heard GREAT things from my friends that have used it.
So, like my son, maybe he is interesed, but just not ready to master the skill of potty training.
Hope this helps!
