Gerber Rice Cereal (過敏)

when my baby is 5 month old, i gave him rice cereal and he had rash. so i thought maybe he is allergic to rice cereal.  but doctor suggested us to give him rice cereal since baby needs a lot more iron than before. so i tried again when he is 7 months and his rash came back. so maybe i'll try organic oatmeal latter.
