Sophie, I'm intrigued! I understand that cow's milk is designed for the digestive system of cows but it raises a few questions (genuine): - does this extend to all dairy products? If so, what would the alternate source of calcium be? If not, why not? - what foods are actually meant for the human digestive tract? Or, are you saying that if solid dairy products are part of the child's balanced diet then there is no need to add a glass of milk in the morning and evening?
