It is not unusual for breastfed babies to have various colors of poop. Green is something everyone worries about and mothers are warned about “foremilk-hindmilk imbalance” causing the poops to be green. But there's no need to worry if the baby is breastfeeding well and is content and gaining weight. To gauge whether your baby is drinking milk well, see the video clips at our website NBCI.ca.
Orange poop is not that unusual either and is normal.
Brown poop (that is consistently brown) may indicate inadequate intake of milk by the baby.
Black (or extremely dark-green) poop or meconium, is normal for the first three days, but if the baby is still having them four or five days after birth, this is a serious concern. For help, see the protocol to manage breast milk intake at our website and get information from the video clips there. Get good hands on help from your pediatrician as well.
Blue poop has been known to be caused by some formulas (though this is very rare). If you are exclusively breastfeeding, you shouldn’t encounter this. If you are supplementing with formula, though, speak to your doctor right away about switching or looking into what the problem may be.
