A few months ago, Colter decided his Duplo man needed a diaper. The Duplo man is only two inches tall! It didn't work so well, and I finally got a tissue out to use instead of a diaper. It was really funny!
He has been more interested in matters of the diaper lately. We got a potty chair a few weeks ago, and he likes to sit on it, pretend to wipe, than flush toilet paper down the toilet. It's a very environmentally friendly game. I have not really tried to get him to actually use the potty yet, but it's here for when he is interested. Maybe he'll potty train himself sometime. :)
