Hi, twin boys 6 week old having combination of similac and breast feeding older one have soft stool but younger one has constipation.

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't give bonnisan drops and some enzyme preparations in pgroper 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 .
