Baby poop color differs according to the type of feeding your baby receives. During the first year of their life, your baby will go through a variety of poop colors, especially as their diet changes. Here's a quick guide for you to check as you stare into that diaper. The Normal Black and sticky: The very first few days with baby, their poop will likely be black and sticky. This is normal, and there's even a name for it specifically: "meconium." Yellow, orange, brown: All aspects of these shades are very common in breast-fed babies. Green(ish): Also completely normal, but often more common when baby is drinking formula where the protein has been either pre-digested or hydrolyzed. Dark Green: This could be due to iron supplements in baby's nutrition. Colors to look out for Red (blood spots): These would be a reason to consult your HCP (health care practitioner/pediatrician) for further analysis. However, if they are in small amount in healthy breastfed babies, this could be "allergic proctocolitis:" a benign condition that doesn't need a medical intervention in most cases. To be safe, however, consult your HCP if you see these spots.. Black (after those first few days): Could be a sign of digested blood. Consult with your HCP if you see those. White: White stools may indicate a liver problem, especially in combination with a yellow tint of the white of the eyes. Contact your HCP if you're seeing this color.
