Should you go for a soy-based formula or a cow milk based formula?

Between the two, there is no difference in terms of nutrients. Soy-based formula does not have nutritional advantage over cow milk-based formula and vice versa. Both are fortified with the same vitamins and minerals. Parents would choose soy-based formula when their baby is sensitive or allergic to cows' milk protein, or when a baby is having trouble digesting lactose or milk sugar. So it's really up to what your baby can or cannot ingest :) http://www.babycenter.com/404_soy-or-milk-based-formula-which-is-better-for-my-baby_1962.bc
