2-month-old baby has green poop—what happens?

Green poop in a 2-month-old is usually not a concerning situation. The most common cause in breastfed babies is an imbalance between foremilk (milk high in lactose, watery) and hindmilk (milk high in fat). If the baby is switched to the other breast before staying long enough on the first, too much foremilk is taken, making stools green and frothy.

Other than that, green color can come from iron supplementation (especially iron drops started in the 2nd month instead of vitamin D), iron in formula, or simply faster intestinal transit.

However, I recommend seeing a pediatrician if: there's mucus in the stool, there's blood, the baby seems uncomfortable, has fever, is vomiting, or is not gaining weight. Green poop alone is not a problem if the baby feeds well, gains weight steadily, and seems content.
