I know people who raised their kids on goat milk because they could not tolerate anything else as infants, even the formulas etc.
I think goat’s milk is under rated. It is very healthy and far easier to digest than cows milk. Especially for the little ones. I am sure many have used it, I have never heard of a doctor recommending it though. My oldest daughter is a nurse and said she learned in nursing school that it was the best alternate to human breast milk out there. Then she told me she had never heard a doctor recommend it. Does not make sense.
