He's a champ at peeing on the potty, but he absolutely refuses to poop on it. He held it for 4 days-until he made himself sick and I finally put a diaper on him and he UNLOADED. I can tell when he's about to go and rush him to the potty but he just puckers up. Now he's taken to pooping in his undies or pull-ups at daycare. Help! I just don't know what to do to get him to poo on the potty. I've gone in front of him (TMI I know), tried bribery, I just don't know what else to do. Suggestions? TIA!
