Hi my ds (7 mnths) has had vomiting and diahorrea frequently since going onto formula - today our gp said he is likely to have an allergy to cows milk. We have bought some soy based formula for now but long term (if is an allergy to milk) I am not so sure as I read that long term use can cause reproductive problems. I was wondering if anyone has tried Neocate or have had any concerns themselves about soy based formula. It's all really confusing!
