its looks like there is red blood in stool of my 2 months old daughter. is it a cause of concern ?

A. Many babies have blood in their stool during infancy. Small anal fissures and other minor conditions may cause blood streaks in a baby's stool. Black stools or severe bloody diarrhea may indicate a cause for concern. More serious issues — such as bleeding in the intestines — may also cause bloody stool, however.
