What does mucus in baby poop mean?

First, a quick spin around the world of baby poop.

Baby poop goes through different stages. In their first few days of life, your baby produces what is called meconium. It’s really dark (almost black) in color, pretty sticky, and filled with all the leftovers of what they ingested in the womb. After that, their poop will turn a greeny-yellow color.

Yep, baby poop can be confusing.

Add mucus to the mix, and it’s hard to know what you’re dealing with.

Suddenly, you’re sending frantic texts to your partner/mom/friend saying “Baby has mucus in poop!”.

Which is really something you never thought you’d have to say, ever.

The thing is, if your baby has mucus in their poop, it may be totally fine. It also may not be.

Your baby’s intestines are working to help move that poop through them.

One way they do this is by secreting a mucus to help with the task.

Sometimes, you can see this mucus in your baby’s poop—and there’s no reason for concern.

Other times, it can signal an allergy, infection, or health condition.

How do you tell the difference? Well, it’s not always that easy.

What does mucus in poop look like?

Mucus in breastfed baby poop is particularly common since their stool passes through the intestine pretty quickly.

It may look like slimy green streaks that run through the poop and/or a bit like jello.

When should I worry about mucus in my baby’s stool?

Mucus in baby poop can simply be the result of drool that has made its way to the other end.

If your baby is teething, they might be particularly drooly at the moment.

Having a cold might mean they have some extra mucus in their system.

But there are some instances when mucus in your baby’s poop is worth paying special attention to.

Mucus in baby poop may be a sign of:

  • Allergy to animal protein, AKA allergic colitis. Your baby may be allergic to an animal protein that they are ingesting through your milk or through their formula. If you’re breastfeeding, this doesn’t mean you have to stop—it just may mean that you have to shift to a dairy-free diet. If you’re using formula, you may have to switch to a more hypoallergenic option.

  • Diarrhea. Bacterial and viral infections can both cause diarrhea, as can a change in their diet or yours. If your baby seems extra fussy, has a fever, or has blood in their stool, it’s definitely worth getting to the doctor. The big danger with diarrhea in babies is dehydration. If you notice your baby hasn’t peed in a while, is crying with no tears, or has sunken eyes and a dry mouth, get to the doctor ASAP.

  • Malabsorption. In some very rare cases, mucus in baby poop can signal a more serious health concern that might affect how your baby takes in nutrients. This can be caused by conditions such as cystic fibrosis—a genetic condition that can damage the respiratory and digestive systems. If your baby has cystic fibrosis, they might have trouble putting on weight, have very foul-smelling stools, and thick phlegm. If you suspect that malabsorption is causing the mucus in your baby’s poop, it’s worth getting to a doctor right away.

The bottom line

In many cases, mucus in baby poop is nothing to worry about.

If your baby has other symptoms, or if the mucus is very heavy and long-lasting, check in with a healthcare professional as soon as you can.

We know this can all be super stressful.

Good luck, mama. We’re rooting for you.
