I'm curious how usual this is. Our oldest grandson just turned three. He's been going potty by himself for just a little more than one year, but has the most unusual method.He shuns the training potty and the little seat which keeps him from falling through the big hole. If an adult tries to help (grandparents, parents, anyone), he pushes them out the door so we have to peek in a crack to make sure he's doing it right. He climbs up on the seat, squats with one foot on each side and dangles his junk down so he hits...
