My son is 2 yrs and 3 months old. He knows how to go to the bathroom by himself, and if prompted to he will do everything by himself even wash his hands. He even does the potty dance to hold in his pee. So I know he understands his body cues. But he just wont stop and go to the bathroom. He will pee his pants then go change his underwear. I have tried everything under the sun. This is after the typical potty training which he was doing great for about a month but now he just has had a major regression.
