Hello Doctor My son is 1 month old from past 3-4 days he is vomiting atleast 2 time's a day after getting a burp also he is going vomiting

A. hello dear this is common Burp in sitting position better than on shoulder keeping the head and chest at a level higher than stomach helps to reduce vomit. if baby is passing urine more than 7 times a day is active and alert and gaining adequate weight ,at least 500 gram per month then do not worry
