<s>[INST] Hi, my daughter is 3 months old. She was born with RH-incompatablity and i was told if her stools are ever brown or gray to take her. but, i recently j strted feeding her ceral in her bottle and her stool last night n this morning was gray-ish in spots. Can rice ceral do this or should i take her to the er? [/INST] You should not give cereals to the baby in 3 month of age. Complimentary feeding should be started at 6 month of age. </s>
