to first comment i agree i think he is jus being defiant. i will try tge cheeros thing.

I've heard that you can potty train a baby boy with Cheerios, throw them in the toilet and he has to score my peeing in the middle! Heard that has helped a lot of moms!

i dont want to sound like the mean mama but my son was like that which showed me he knew to go to the bathroom just refused with me and his dad so for two days we only wore underwear ( except to bed) and every time he weat his underwear we popped his butt it only took two days and now he is potty trained with us.
