I put ds in real underwear yesterday. He held it from 7am to noon. Once he had a pull up on, he immediately had a big pee and poop. He did sit on the potty a few times, but wouldn't do anything. Is this a sign that he's not ready? I don't want to force him if he 's not ready. I 'm just confused because last week we had 3 pees on the potty and now nothing. Wwyd?
