Goats milk is the closest milk to breastmilk out of all the non-human milk options
Actually I believe that is a myth. I have heard that from many places but I have heard some very well-respected paediatricians (with an international reputation) speak on this topic and apparently the statement is not true and goats milk is not recommended for young children as it has totally the wrong balance of proteins, fats etc. If my memory serves me 'Dr V' - Dr Bryan Vartabedian who wrote the brilliant book "Colic Solved" - is one of them (I hope I got that right!!).
