My newborn (8 days)hasnt had a bowel movement in 2

Patient: My newborn (8 days)hasnt had a bowel movement in 2 days. Is this an issue of immediate concern?

Doctor: Hello dear,Thanks for trusting us about your health care.I can understand your concerns.Newborn can pass motion in every 2-3 days or 7 days or they may pass stool 3-4 times in a day, all considered normal.But he should pass urine and flatus that is very important.You should change your diet, if he is on breat feed.Hope it is useful, feel free to ask more.Regards
