Different colour of poop

If you're a new parent, you might think about your baby’s poop more than you ever thought you would. Different colors and textures pop up all the time. During the first 24 hours of life, a newborn will pass meconium. This is thick, black stool. What a baby eats makes a difference in what winds up in their diaper. The body tends to absorb breast milk more completely -- sometimes there’s so little left that a baby may not poop for days. On the other hand, many breastfed babies pass a mustardy, "seedy" yellow stool with each feeding, at least for a short while. Formula-fed babies tend to have darker, tan-colored stools that happen less often. But remember: Every baby is different, and there is a very wide range of normal when it comes to poop. The color and timing of a baby’s poop changes as their diet changes, as their digestive tract matures, and as it gets more new, normal bacteria. It's rare that color changes are signs of a digestive problem. Usually, they just mean that there is more or less of the yellow/green/brown/orange pigments that stool picks up along the way.
