Some kids draw on the walls, mine color their hair. My daughter and son think being blond is "too boring" and took changing things up into their own hands . . . and heads. Since we exhausted wigs and hair pieces and dye has been vetoed, my 6-year-old let a red marker bleed onto a carefully selected clump of her hair (Julia Roberts style), and a few days later my son drew a blue circle on his head. A $3 pack of washable markers made them happy until shampoo washed away their artistic expression.
