#AskTheExpert 1month old baby is passing stool of dark color (pic attached) with very strong smell. Baby is inactive and sleeping all the time.. Also she is moaning in sleep.

A. hi dear Stools are normally brown due to a pigment called bilirubin. Bilirubin is made in the liver. Bilirubin starts off a greenish-yellow and from the liver it is secreted into the small intestine with meals. As it travels through the intestine and is broken down by the body, it becomes brown.
