There's all sorts of people allergic to every sort of protein imaginable - why not breastmilk proteins? Sure, most of the time, it will be a foreign protein (cow's milk, peanut, whatever), but is it really "impossible" to be allergic to the breastmilk protein? I always thought any protein was capable of triggering the allergic response. This, of course, would not be compatible with human life, in earlier times, but that doesn't mean it can't happen. Laurie >> Here is a quote from "The Womanly Art of Breastfeeding": "Protection against allergy is one of the many advantages a baby receives from his mother's milk. Your baby will not be allergic to your milk; you can count on this with certainty. It is a law of nature that infants never become sensitized to their natural food. Proteins make the critical difference. The protein in your milk is totally compatible with your baby. The proteins in cow's milk and in formulas based on cow's milk are potential trouble makers for the human infant." Kim
