Did you really think you would be excited to learn about baby poop? Well, that’s what happens when you have your first baby. And from talking to mothers with grown children, they still like talking about it.

It’s the first thing that happens when you bring your baby home. It’s a bonding experience with mom, dad and baby. It’s as natural as breathing. And it’s not going to go away…no matter how much Dad wishes it would.

So it’s time to learn everything you’ll need to know to impress your mother-in-law, entertain your friends and give yourself a little peace of mind.

Newborn Poop. What’s Normal?

You bring your baby home and you know your baby is going to poop. But did you know there are stages of newborn baby poop?

Stage 1: Meconium Poop

This is your baby’s first poop. It’s usually tarry black and will stick to your baby’s skin. And the good news…it has no smell! It contains everything that was in your baby’s intestines during pregnancy. But don’t fret because it’s black and tarry…it means everything is working properly.

Stage 2: Transitional Poop

This poop shows up after your baby’s first day, and is brown or green in color. It’s no longer sticky and may contain milk curds or “seeds.”

Stage 3: Milk Poop

This poop appears around the 3rd day and is affected by how you feed your baby. If you breast feed, your baby’s poop will be loose, yellow curdy and look like mustard. And there will be a lot of poop. IT’S A GOOD THING!—It’s not diarrhea…just means your baby is getting enough to drink and gaining weight!
If your baby is formula fed, the poop will be yellow to tan with an odor. It will be more pasty, like peanut butter, and you’ll also see fewer and larger poops.

Poops of Concern

Most of baby poop is absolutely normal, but it pays to keep your eyes open for a few poops that may need closer attention. Consult your health care provider if you notice any of the following:

• Blood in your baby’s poop
• Dark sticky poop (meconium) after baby’s 4th day of life
• No poop in the last 24 hours if baby is less than 3 weeks old. Can be normal but make sure baby is drinking well.

The Colorful World of Baby Poop

Yes, new mother. Baby poop comes in colors. And each color means something that you need to know regarding your baby ‘s health and wellbeing.

Let’s start with baby’s first poop, the one that may not make it into the photo album, but will forever be etched in your memory:

Darkish Green-Black

Baby’s first poop, called meconium, is usually sticky and is made up of everything your baby ingested in utero, including amniotic fluid, skin cells and water.

As your baby continues to become acclimated to a new environment, the color of poop takes on an array of colors.

Here are the other colors you will notice:



Colors of Concern

What do the colors white, red and black have in common? These are the colors you should be on the look out for that will prompt an immediate call to your pediatrician.




Food additives

Keep a watchful eye on any products you are feeding your baby, and keep in mind that the foods you eat will show up in your breast milk…and can be passed on to your baby. 

Be mindful. Be careful. Be happy when your baby’s poop is the color of healthy.
