How can it possibly be true that babies need cow's milk because there is a protein missing in breast milk?? What about all the babies around the world and throughout history who NEVER have cow's milk (including a couple of mine)? How can anyone, even a doctor, believe that Mother Nature forgot to put an essential protein in breast milk, requiring the human species to domesticate cows so that human babies can survive?? This just drives me crazy. (Oh, Jack - sorry for the "even a doctor" crack. I didn't mean you.) Teresa
