Have you ever tried bathtub body paint? I get it from Avon and my 2 and a half year old knows that the only way she can paint with it is if she gets in the tub. I always make sure I have some. They come in different colors and they are dirt cheap! They are totally skin safe. Both my kids have skin allergies and this stuff has never broken them out. It's the only stuff I have found that doesn't irritate their skin.
