My 7 month old DS2 has been on Neocate for about 4/5 months for Cow's Milk Protein Allergy. He saw a gastroenterologist recently and we have been advised to do a soy formula challenge when DS2 is 9 months old. I believe that there are only 2 soy formulas on the market - Karicare and S26. Can anyone recommend one over the other? I have a bit of a bee in my bonnet about Karicare, but I could be wrong (maybe!).
