What’s the Scoop on Newborn Poop?
Dr. Joseph is here to answer all your questions!
As a pediatrician and the mom of a newborn, I spend an inordinate amount of time thinking and talking about baby poop! Shout-out to Dr. Sexter (my baby’s doctor!) for entertaining all the questions my husband and I have about our daughter’s poop. Let’s dive in.
The First Poop: Meconium
Your baby’s very first stool is called meconium. It’s thick, sticky, and dark greenish-black—almost like tar. This forms during pregnancy and is made up of materials your baby swallowed in the womb, such as amniotic fluid and cells. Your baby should pass meconium within the first 24-48 hours after birth. Beware, it is incredibly hard to wipe off their soft newborn skin!
The Transition
After a few days, stools begin to change color and texture as your baby starts digesting breast milk or formula. After meconium, baby poops are usually loose, yellow/brown (or even green) and are often seedy/grainy.
Colors That Are Normal (and Not So Normal)
Newborn poop comes in an impressive range of shades. Here’s a quick guide:
Usually Normal:
- Yellow
- Green
- Brown
- Slightly orange
Green stool, in particular, often causes alarm—but it’s usually related to digestion speed and is not typically a concern by itself.
Call If You See:
- White or pale gray (may indicate a liver issue)
- Black after the first few days of life
- Red
When in doubt, take a photo to show us. We’ve seen it all!
How Much Should My Newborn Poop?
Poop frequency varies widely! It can be normal for a baby to poop 8 times a day, up to every 8 days, or anywhere in between.
Volume of stools can vary as well. Some stools may look like small smears in the diaper, while others may be full-on blow outs that ruin that cute new outfit you just dressed them in.
Why is she Straining?
Newborns often grunt, turn red, and appear to strain before passing stool. This is typically due to immature coordination of abdominal muscle tightening and pelvic floor relaxation—a common and harmless condition called infant dyschezia.
Diarrhea in Newborns
Because newborn stool is normally soft, diarrhea can be tricky to identify. Signs that may suggest a problem include:
- Sudden increase in frequency
- Very watery consistency
- Blood or large amounts of mucous
- Signs of dehydration (fewer wet diapers, dry mouth)
Always remember—no question is too small (or too gross) to ask your pediatrician. When in doubt, take a picture and give us a call!
