My son is now 3.5 yrs old and still isn't fully potty trained. He goes #1 in the potty like a big boy, but when it comes to #2, he simply refuses and would rather do it in his pants. Even when I catch him in time, I put him on the potty and tell him to go #2 there, he will sit for up to an hour, refusing to do his business there. Why is it that some children rather poo in their pants? I don't see why that would be satisfying.
