B..
Your child should be on some kind of formula until 12 months. After that, he does not NEED milk, unless he has a very incomplete diet. I have a milk protein allergy. This means I can NOT drink goat's milk. (Also, it's very expensive.) Lactose intolerant people can sometimes do well on goat's milk, because the lactose proteins are smaller. However, with an actual milk allergy, it doesn't matter how small the proteins are. A true milk allergy can't handle goat's milk. Anyway...I have gone my whole life with no milk. I have great health, and I did as a child. My son is 3, and he does not drink milk. He has a very nutritious diet gets his vitamin D from sunshine. (Milk does not actually have good amounts of natural vitamin d, it's mostly added synthetically.) Like I said, when your child turns one...if he has a good balanced diet of proteins and lots of veggies and fruits...he doesn't need to drink milk.
