Normal baby poop can be greenish-tan. It can also occur in babies who are teething or when they have just gotten over a stomach bug. If your baby regularly has greenish-tan poop and is also fussy at feedings, gassy and uncomfortable they could be experiencing a cow’s milk allergy from their formula.

Bright Green

Newborns are more commonly affected by bright green poop and one cause of it could be an imbalance of foremilk and hindmilk. Mothers with an oversupply who breastfeed may notice this baby poop color more often.

Foremilk is high in sugar and less fatty than hindmilk. Foremilk is usually clear or blue in color and it tends to be the milk baby gets at the beginning of a feeding. 

To correct this imbalance, mom should express some of the foremilk before a feeding so baby gets a better mix of both foremilk and hindmilk.

Bright green baby poop can also indicate a tummy bug or a sensitivity to a food or drug. When a baby reacts negatively to their breastfeeding mother’s diet this can result in mucusy bright green poop as well.

If you have a teething baby, you know all about the extra drooling. This excess drool also ends up back in baby’s stomach which can create a mucusy texture and looser than normal stool.

Teething babies also tend to have greenish colored poops due to the increased amounts of saliva they swallow.

Bilirubin is what makes newborn’s stool mustard or dark yellow. If your baby is receiving phototherapy to treat Jaundice, they might have frequent dark green or black stools as the bilirubin is being removed from the body.
