Newborn poo: a quick and dirty guide

Before your baby came into the world, you may not have wanted to spend much time thinking about anyone’s bowel movements, but it’ll be a while before she will be able to tell you in words if something is wrong, so in these early days, what’s coming out of her digestive tract can speak pretty loudly.

On the other hand though, there is a lot of variation in what’s normal for newborns and their pooping habits. If your baby seems healthy, has relatively soft stool, and is gaining weight, there’s probably nothing to worry about.

Now that your baby is a few days old, she will probably have finished excreting most of the meconium that coated her intestines during pregnancy, and will have moved on to a fairly liquid, yellowy-green mixture, though little dark flecks of meconium may show up in her new, yellowish stool for a little while longer. your baby will probably start by pooping between three and five times a day, before settling in to the schedule that’s right for her. This could be as many as eight times a day, or as infrequently as every other day, or even more infrequently in some rare cases. As she gets a little older, this pattern will even out pretty quickly, and by the time your baby is about 3 weeks old, she will probably be pooping on a pretty regular schedule. And if she has been pooping a lot, which is common in breastfed newborns, she may settle into a pattern of pooping less often.

What kind of newborn poop is normal if I’m breastfeeding?

If you’re breastfeeding, your baby’s pooping schedule, when she settles into one, may be pretty infrequent, because your breast milk may be well balanced enough for your baby’s system that there won’t be a lot of waste. On the other hand, though, she may poop as often as after every feeding, since she can metabolize breast milk so easily.

your baby’s stool texture will probably be fairly loose and soft, with a curdled quality from the milk solids, ranging from yellowish to greenish.

What kind of newborn poop is normal if I’m feeding your baby formula?

Newborns who are formula fed from the start, as well as those who have transitioned from breastfeeding to formula-feeding, will have a slightly different texture of stool, because your baby may be able to digest less of the formula. This means that her regular stool may be thicker and more solid in texture, may be more yellow-to-brown than yellow-to-green in color, and may be stronger smelling. Formula-fed newborns often poop less often than breastfed ones, so as long as your baby is developing healthily and gaining weight the way she should, any pattern she gets into is probably healthy.

What to look out for

Some variation in your baby’s poop is normal, and most color changes (from yellow to green to brown) just have to do with how much time it takes her to digest. There are some changes in color and texture that could mean trouble though, so it’s important to know what these are.

If you notice that your baby’s stool is coming out red, black or white, you should definitely call the doctor. White poop could be a sign of an infection or jaundice, while red or black could mean trouble with either fresh or digested blood.

And as far as constipation goes, texture is a better indicator than is the time between bowel movements. Poop that is hard or pellet-like (either small and dry or large and hard) is probably signs of constipation, which can be caused by dehydration. If you notice something like this, it’s a good idea to check in with the doctor.

On the other hand, watery or runnier-than-normal poop, especially in large amounts very quickly, could be diarrhea. Diarrhea usually clears up on its own, but if it sticks around longer than a day, it's a good idea to check in with your doctor, just to be safe. Diarrhea can be a sign of an infection, a food allergy, or a reaction to a medication.

A look into the future

your baby’s poop, just like the rest of her, is going to keep changing, and the next big shift will happen when she starts eating solid food. Breastfed babies' poop might grow more solid when she starts solids, while formula-fed babies' poop might become looser and runnier, but there’s no one standard way that her dirty dipeys will change once she reaches this point, except for a more poopish smell - you can pretty much count on this.
