kids who not feed by their mother end up having weak immune system for whole life,.
my sisters breast fed all 3 of her kids til age 2..... exclusively (no bottles). They are always sick. Then have my little cousins who were bottle fed.....they dont get sick as much.
breastmilk is best of course no doubt. but this evidence they tell us about breastfed kids having a stronger immune system seems bogus to me.
