My sister has a 5 month old baby and I was talking to her today about breast milk. She was telling me that the consistency of her milk changes as Harry's requirements change. How does this work? How does her body know to change the consistency? The only explanation I can think of is that the baby gives off pheremones signalling that it requires more protein/calcium/whatever, and the mother's body picks up on these pheremones and responds by adjusting the milk accordingly. Any experts care to comment?
