it doesn't smell like normal baby spit up. He is 3 1/2 months old, and currently breastfeeding, formula feeding, and eating rice cereal (sometimes plane and sometimes with banana or pears in it) which was recommended by his doctor. Last week he was really sick with bad coughing, a fever, and some diarrhea. He since has gotten a lot better, but when he spits up it smells really sour like the through up of an older child. Any ideas of what could be wrong?
