Let your kid draw on the bathroom floor with washable crayons
Elizabeth's toddler art solution:
My son is just about to turn two. He loves to color, but gets very frustrated at how the paper slides around on the tile floor. So I give him washable crayons and let him color directly on the floor! When he's done, I take some pictures of the latest masterpiece, then break out the Swiffer WetJet or a sponge and clean up!
The only problem I could see with this is if he gets the idea that any crayon can be used to color on any surface (floor, wall, etc.). But it's different for every kid! I had one who would color on anything he could reach, and another was born a neatnik.
