Your self-determined toddler can sometimes present a challenge when it comes to brushing her teeth. Try this: Sit on the floor cross-legged, placing your child on her back, resting herself on your leg. You are now looking down at her, while she is looking up at you. Let your child brush your teeth while you brush hers. You'll get loads of cooperation, as well as a good look at those molars! Connie Giarratana, M.D.
