My 5 month old was dry heaving and vomiting what appeared to be water.  He is on formula with small amounts of rice cereal mixed in.  His tummy sounds bubbly and he is passing gas that smells like rotten egg.  Need for alarm or to see his normal pediatrician?
Thanks for consulting in Chat Doctor. I think you should stop to introduce cereal till she will well, better start later, from 5,5 months. The digestive system is not ready eat. It is heavy for her, he doesn't have enough enzymes. Nowadays, we usually introduce solids from 6 months, we start from boiled potato or cereal. I advise to your bay for improving digestion take eco norm(saccharomyces) 1/2 Sasha 2 times 3 days, then Darla 1 caps 1 time 1 month(open capsule and give powder with small amount of water), it is our normal flora, which take part in digestion. From nausea and vomiting give to your baby antiemetic- coastal or ondansetron, keep HY Chat Doctor.
