Kids are smart, aren't they? He's waiting until he has his pull-up on to poop. That alone says that he's ready... having control over his bowels like that. My boys used to BEG me to put a diaper or pull-up on them so that they could poop... because they hated going on the potty. One thing that helped them was taking them to Toys R Us and picking a toy that he will get to have when he goes poop on the potty. Maybe take a picture of it even, to remind him at home that the prize is his as soon as he goes poop on the potty. What a joyous day that will be for everyone when it happens!!!
