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 cagyn give bonnisan drops and some enzyme preparations in proper dose suggested by doctor and cow's milk should be avoided before 1 year of age . Medicrations are required but it should be given only in medical supervision .
