Whether you’re a new or seasoned parent, I’m sure you can agree: your baby poops a lot, and you talk about it even more. You’re constantly wondering when the next poop is coming, which diapering essentials are worth buying and why it suddenly feels very concerning when there’s not enough poop.
And let’s be honest, it’s confusing! Why is today’s poop light green when yesterday’s was dark green? Is it normal that my baby poops three times before lunchtime? And why are we suddenly in the middle of a poop strike? If you’ve ever stared into a diaper with extreme confusion (and maybe mild concern), just know I’ve been there. Millions of other parents, too.
To help you make sense of it all, we’re breaking down everything you need to know about the poo-niverse and how to accurately decode what’s happening in your baby’s diaper. So grab a fresh pack of wipes, take a deep breath and let’s dive right in.
Baby’s first poop.
Your baby’s very first poop is a big deal. In fact, it’s a full-on milestone. Your baby’s first poop is called meconium, and it’s thick, sticky and black or dark green in color, with a tar-like consistency. Meconium is made up of materials your baby accumulated in their intestines before birth, and typically passes within the first few days of life, most often within the first 24 to 48 hours after birth.
Once your baby poops meconium, their stools will begin to change in both color and consistency. These changes are normal and largely depend on how your baby is fed, whether through breast milk or formula (more on that below).
Breastfed vs. formula-fed poop patterns.
Every baby is different, and so is every baby’s pooping pattern. That said, stool frequency, consistency and color are largely influenced by how your baby is fed. Understanding what’s typical for breastfed versus formula-fed babies can help you know what’s normal and when to check in with your pediatrician.
Breastfed babies
Babies who drink breast milk generally have yellow, seedy (small, grainy bits that look like tiny seeds) poops that are very soft, loose or runny. In terms of frequency, it can vary widely. In general, breastfed babies tend to poop more frequently than formula-fed babies.
Some babies have multiple bowel movements per day, while others may poop only a few times per week, and both patterns are considered normal. As long as your baby’s stools are soft and easy to pass, and your baby is feeding well and gaining weight appropriately, infrequent stools are generally not a concern. Always check with your doc!
Formula-fed babies
Babies who drink formula tend to have stools that range in color from yellow to green. Their stools are usually firmer than those of breastfed babies, though they should still be soft. Formula-fed babies often have more predictable bowel movements and typically poop at least once per day. If your baby is having fewer bowel movements and appears to be straining and uncomfortable, this may be a sign of constipation. In this case, it’s best to check with your pediatrician for guidance on how to manage it safely.
What’s normal vs. what’s not?
It can sometimes be difficult to tell what’s normal and what may be a problem, especially in young babies. Here’s some general guidance:
Diarrhea
Diarrhea can be tricky to identify, particularly in breastfed babies whose stools are normally loose. Signs of diarrhea include a sudden increase in stool frequency and stools that are more watery than usual. If you suspect your baby has diarrhea, it’s important to contact your pediatrician.
Constipation
True constipation isn’t too common in babies, especially in newborns, but it can happen. Signs that your baby may be constipated include hard, pellet-like stools, poop that is difficult or painful to pass, or fewer than two bowel movements per week. If your baby seems very uncomfortable, is in pain or you notice blood streaks in their stool, contact your pediatrician for next steps.
It’s important to remember that grunting, turning red or straining while pooping is completely normal. Straining only becomes a concern if it lasts longer than 10 minutes or appears very painful.
A guide to baby poop colors.
Baby poop comes in a whole spectrum of colors, and most of them are totally normal. However, some colors can signal an underlying issue. Here’s a chart to guide you:
Should baby poop stink?
Unlike adult poop, baby poop usually isn’t very stinky, especially in newborns and before they start solids. In general, breastfed babies’ stools have milder smells, while formula-fed babies’ stools can have a bit more odor, though it’s usually nothing that makes you want to squeeze your nostrils shut. Once your baby starts eating solid foods, their poop will become more pungent, and you might want to wrap dirty diapers in a bag or invest in a diaper pail.
Psst: If you notice unusually foul-smelling poop, it could be a sign of a food intolerance, allergy or another health issue, so it’s a good idea to check in with your pediatrician.
Why do babies poop so much?
Let’s wrap up by answering the age-old question: why do babies poop all the time? Even though the frequency of bowel movements varies from baby to baby, many pass a poop soon after breastfeeding or a bottle. This happens because of the gastrocolic reflex—a natural reflex that triggers the digestive system to get moving whenever the stomach is full. TLDR; milk goes in and poop often comes out shortly after.
At the end of the day, poop is simply part of life with a baby. Some days it feels like a miracle how quickly milk turns into diapers. Other days, you’re wondering if you’ll ever reach the bottom of the diaper stash. Either way, you’re not alone in this messy + surprisingly fascinating stage—and we’re here to help, every step (and diaper) of the way.
