New parents spend a surprising amount of time thinking about poop, and for good reason. Your baby's bowel movements can tell you a lot about their health. When things slow down, it is natural to wonder if something is wrong.

The truth is that baby poop habits vary enormously, and what looks like constipation is not always a problem. Here is what you need to know to tell the difference and when to check in with your pediatrician.

What Is Normal for Baby Poop?

Before we talk about constipation, it helps to understand the wide range of normal:

Breastfed Babies

Breastfed newborns may poop after nearly every feeding, sometimes 8 to 12 times a day. After the first month or so, many breastfed babies naturally slow down and may only poop once every few days, or even once a week. As long as the stool is soft and your baby seems comfortable, this is usually normal. HealthyChildren.org notes that some exclusively breastfed babies can go up to a week between stools without being constipated.

The thing pediatricians wish parents knew: frequency is almost never the issue. Consistency is. A breastfed baby who poops once a week with soft, mushy output is fine. A baby who poops twice a day with hard pellets is constipated. If you are tempted to call for "he has not pooped in 4 days," first ask yourself whether he seems comfortable and whether the next stool, when it comes, is soft. That one question saves most unnecessary ER trips for infant constipation.

Formula-Fed Babies

Formula-fed babies tend to have more predictable patterns and typically poop at least once a day. Their stools are usually firmer and darker in color than those of breastfed babies.

Babies on Solid Foods

Once your baby starts eating solid foods (usually around 6 months, with your pediatrician's guidance), their poop will change in color, consistency, and smell. This is also when constipation becomes more common.

Signs of Constipation

Constipation is defined by the consistency of the stool, not just the frequency. Your baby may be constipated if you notice:

Common Causes

Several things can contribute to constipation in babies:

Straining vs. Actual Constipation

Here is something that surprises many new parents: it is completely normal for babies to strain, grunt, and turn red while pooping, even when they are not constipated. This is sometimes called "infant dyschezia." The Mayo Clinic's overview of constipation in children draws the same line we draw here: hardness of stool, not amount of grunting, defines whether it is actually constipation.

Babies are still learning how to coordinate the muscles needed for a bowel movement. They may push and strain for several minutes before producing a perfectly soft, normal stool. If the stool that eventually comes out is soft, your baby is not constipated, even if the process looked uncomfortable.

True constipation produces hard, dry stools. If your baby is straining but producing soft stools, this is usually not a concern. Talk to your pediatrician if you are unsure.

What Can Help

If your baby does seem constipated, here are some things that may help. Always check with your pediatrician before trying home remedies, especially for young babies:

When to Talk to Your Pediatrician

Contact your pediatrician if:

Your pediatrician can determine the cause and recommend safe, appropriate treatment for your baby's age. If you are having trouble remembering the last few days of diapers when you call, a quick diaper log gives you an honest two-week picture to read from.
