I'm on day 3 of potty training. It's going well. Day 1 was crazy, but day 2 we only had 2 accidents in the morning. So far day 3 is going very well, no accidents.

I'm looking for advice on getting my son to poop in the potty. Day 1 he pooped twice in his underwear. He didn't go poop yesterday. He'll probably go sometime today. I really want him to try to go in the potty, but he won't sit on the potty for any longer than the time it takes to pee.

Suggestions?
