I give my 14 m/o a bottle of cow's milk before bed (after bath and teeth-cleaning), which makes her nice and sleepy. But I've just read that this is really bad for baby teeth, and I should be cleaning her teeth after the bottle. She goes mental when I brush her teeth, so I'm reluctant to get her all awake and angry just before bed! She only has six teeth at the front, so should I be worried? Has anyone experienced actual tooth decay as a result of bedtime milk?
