I used character underwear to enforce the potty training. My son’s favorite character was Mickey Mouse and you can’t go peepee on Mickey Mouse. So he was very good about it when he wore his big boy pants, it is important to use regular thin briefs not padded or training pants. Be prepared for accidents. Try to time the trips to the potty. Run water when he is standing or sitting on the potty. Keep the potty in the bathroom. Stress the big boy part of the whole thing and if there is even a little drop, praise him. Good luck.
