My baby is 9 months old now from last 3 4 days he is vomiting during eating... if I burp him 2 3 times between feeding he is fine otherwise vomits everything.. what could be the reason and any suggestions to avoid this

A. vomits and make faces to throw as taking meals.. baby will do if baby have no interest having food, forcefully fed.. keep baby well hydrated.. maintain gap between feeds.. give small feeds.. try developing food interest.. add variety and creativity.. you can give saunf water for good digestion..
