Everything Melissa said about cow's and other animals' milks I have heard too. I fully agree with her. Cow's milk is for calves, goat milk for kids, and human milk for human babies. A doctor told me human babies make lactase (milk enzyme for digestion) for mother's milk up to 14 mos. old and then it tapers off. After that we shouldn't drink milk because of the antibodies we produce because of it. Cow's milk has been implicated through research as the culprit in certain autoimmune diseases, because of these antibodies.
