my baby is going to 4 month old in few dys.. m giving him nan pro formula powder milk .. bt aftr burp he vomit milk....why its hpning???

A. dear it 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
