Ever since I handed Elizabeth her first pen or pencil months ago, she has been good about only coloring on paper. Of course I supervised her very closely, but she never tried to color on herself or any other object. Recently, she has been wanting her crayons more than any other toy. It seems she has discovered, their "power". Not only do they color on paper, but walls, booster seats, mommy's tupperware, etc. Oh boy, this will be a hard habit to break!
