What to do when my 4 and hlf month old child did not poop for last 3 days. He had 30ml of bottle feed as well in last 3 days

A. Constipation in Babies less than 1 year is very common and more in formula fed babies and also when initially the semi solid food has been started after 6 months . you can give bonnisan drops ahjnd some enzyme preparations in proper dose suggested by doctor and cow's milk should be avoided before 1 year of age . Medications are required but it should be given only in medical supervision .
