my baby doing green with white granules liquid type potty . what is the reason behind that ?

A. white colour / greyish white stool can be a normal phenomena many times when the child is taking formula milk. in other cases you will have to rule out some liver pathology which might be causing this problemz. if it continuous beyond 3 days it is advisable to get a stool examination and urine examination along with physical examination by the doctorz
