dear ******
thanks for writing to health care magic
small amount of regurgitation of milk by breast fed baby is normal.............and not a cause of concern particularly if the baby is gaining weight normally.......and no other problems exist...........
proper burping will help to reduce the problem
no medication is required for this condition
regarding
constipation part........................
a breast fed baby may not pass stool for 3-5 days occasionally and some time they pass 5-6 stools per day...................not a problem if not associated with any other problem
take care
