My son will go potty when reminded (though sometimes he has to be bribed), will poop in the potty if he happens to be there when he needs to. Sometimes he will go days without a wet pull up. But he won't tell us he needs to go, unless we are out and about, because he likes seeing the different bathrooms. And if I can tell he's about to poop and try to take him to the potty he gets really mad and tells me to go away. He gets really excited when he uses the potty, he knows it's a good thing. He tells me when he needs to be changed. And he begs to wear his big kid underwear. So why aren't all the pieces connecting? Any ideas?
