You'll never care about (or talk about) poop as much as you will when you're a brand-new mama. From the color to the texture to -- sorry -- the odor, you'll wonder, "Is this normal?" almost every time you change your baby's diaper. And that's a good thing! "The extra attention to stool is very well-deserved," says Laura Jana, MD, co-author of Heading Home with Your Newborn: From Birth to Reality. "Your baby's poop tells a whole lot about how he or she is doing with eating." So get over any squeamishness over the squishy stuff, and check out our baby poop primer.
What it is: Meconium When: Within the 24 hours after birth What you need to know: You've probably never seen something as sticky, thick, tar-like and greenish-black as your baby's first poo. Meconium is "what’s been sitting inside the intestines while the baby is forming," says L.E. Wolovits, MD, a general pediatrician at Children’s Medical Center in Dallas and an assistant professor of Pediatrics at UT Southwestern Medical School; it's a combination of amniotic fluid, mucus and cells shed during the baby's development. It's also extremely messy and sticky! Expect to be cleaning up a meconium mess for a while. The good news is that the meconium stage only lasts a few days.
