She will gonna like it soon mommy.. my son has allergic reaction to any kind of milk too. We used nutramigen when he was 9 mos - 1 yr and i switched to NAN HA infinipro after that. At first, he didnt like the taste but wala na syang choice bec. i stop breadfeeding na dn so ayun no choice na sya and he like the milk na after a couple of days. Basta ipatikim mo lang sa kanya everyday
