A lot of things can cause tooth decay. You guys would have us believe one should only give their kids whole wheat and lettuce apparently. I don't see that letting one's kids drink milk in a bottle until they are 7 in the DR will have any more adverse effect than them growing up in the States and eating what kids commonly do. BTW, both my other daughters who both drank milk, mostly chocolate after they were 2, until they were 4 have no cavities. Next.
