Most newborns who seem constipated are actually not. Newborns frequently strain, grunt, turn red, and cry before passing a bowel movement, and this is almost always normal. True constipation in newborns, meaning hard, dry, pellet-like stools that are difficult or painful to pass, is uncommon, especially in breastfed babies. Understanding what’s normal and what’s not will help you figure out whether your baby needs intervention at all, and if so, what’s safe to try.
Straining Isn’t Always Constipation
There’s a condition called infant dyschezia that looks alarming but is completely harmless. Babies with dyschezia strain, cry, and turn red for 10 minutes or more before passing a perfectly soft stool. It happens because they haven’t yet learned to coordinate the muscles needed to push: they bear down while simultaneously tightening their pelvic floor instead of relaxing it. This resolves on its own as their nervous system matures, typically before nine months of age.
The key distinction is the stool itself. If your newborn is straining but eventually produces soft, seedy, or pasty stool, that’s dyschezia, not constipation. No treatment is needed. If the stool comes out hard, dry, or in small pellets, or if your baby is clearly in pain during and after passing it, that’s more likely true constipation.
What Normal Newborn Stools Look Like
How often your baby poops depends heavily on how they’re fed. During the first month, exclusively breastfed newborns average about five bowel movements per day, while formula-fed newborns average around two. By the second month, breastfed babies still produce about three stools daily compared to one or two for formula-fed babies. Breastfed stools are also noticeably more liquid.
Here’s a counterintuitive detail: breastfed babies are actually more likely to go through stretches of infrequent stooling than formula-fed babies. About 28% of breastfed infants experience at least one episode of infrequent stools, compared to 8% of formula-fed infants. A breastfed baby who suddenly goes several days without a bowel movement but then passes a large, soft stool is not constipated. Breast milk is so efficiently absorbed that sometimes there’s very little waste left over.
Safe Home Remedies to Try
If your newborn is producing hard, uncomfortable stools, there are a few gentle things you can do at home.
Bicycle Legs
Lay your baby on their back and gently move their legs in a pedaling motion, as if they’re riding a bicycle. This helps stimulate the muscles of the intestines and can relieve gas pressure at the same time. Do this for a minute or two, several times a day.
Tummy Massage
Place your baby on their back on a soft surface in a warm, quiet room. Using gentle pressure, massage their belly in a clockwise direction. Start at the lower right side of their abdomen and move in a half-moon shape to the lower left. This follows the natural path of the large intestine. You can also try “paddling,” where you use the flat edge of your hand to gently press down from just below the rib cage to the lower belly, alternating hands. A baby-safe oil or lotion can reduce friction and make it more comfortable. Watch your baby’s cues throughout. If they seem distressed, stop and try again later.
Warm Bath
A warm bath can relax your baby’s abdominal muscles and encourage a bowel movement. It also tends to calm fussy babies, which can help if they’re tense from straining.
What About Juice or Extra Fluids?
For babies under six months, small amounts of sorbitol-containing juice (prune, pear, or apple) can help soften stools. Sorbitol is a natural sugar alcohol that draws water into the intestines. The recommended amount of prune juice for babies under six months is 1 to 3 milliliters per kilogram of body weight, which can be diluted with an ounce or two of water. For a 10-pound newborn, that works out to roughly 1 to 3 teaspoons. This is worth discussing with your pediatrician before trying, particularly for very young newborns.
Do not give your newborn plain water to drink. Their kidneys can’t handle excess water, and even small amounts can dilute sodium levels in the blood dangerously. Water intoxication in infants can cause seizures, brain damage, and in severe cases, death. All of your baby’s hydration should come from breast milk or properly mixed formula.
Formula-Feeding Considerations
If your formula-fed newborn is consistently constipated, double-check that you’re mixing the formula exactly as the package directs. Adding too much powder relative to water is a common mistake that leads to both constipation and dehydration. Even a slightly concentrated bottle can make a difference for a newborn’s small system.
Some parents wonder about switching formulas. There’s no single formula type that’s universally recommended for constipation, and switching without guidance can sometimes create new digestive issues. If proper preparation doesn’t resolve things, your pediatrician may suggest trying a different formulation, but this is worth a conversation rather than trial and error on your own.
Glycerin Suppositories and Rectal Stimulation
You may see glycerin suppositories marketed for children, but the labeling on these products specifies that children under two years old should only use them under a doctor’s direction. The same applies to rectal thermometer stimulation, a technique some parents hear about through word of mouth. While a pediatrician may occasionally recommend one of these approaches for a specific situation, they’re not something to try at home without being told to do so. Used incorrectly or too frequently, rectal stimulation can create a dependency where the baby’s body starts to “wait” for the stimulus before producing a bowel movement.
When Something More Serious Is Going On
True constipation in the first few weeks of life is unusual enough that it sometimes signals an underlying condition. If your newborn didn’t pass their first dark, tarry stool (meconium) within the first 48 hours after birth, that’s significant and should already have been flagged by your birth hospital.
Take your baby to the emergency room if they vomit anything green or bile-colored. Green vomit in a newborn can indicate a bowel obstruction and is always an emergency. Yellow spit-up, which is stomach acid, is not the same thing and is far less concerning. You should also seek prompt care if your baby is vomiting repeatedly and their belly looks swollen or feels firm to the touch.
Other signs that warrant a call to your pediatrician: your baby hasn’t had a bowel movement in several days and seems uncomfortable, there’s blood in the stool, they’re refusing to eat, or they seem unusually lethargic. A newborn who isn’t producing enough wet diapers (fewer than six per day after the first week) alongside infrequent stools may be underfed rather than constipated, which is a different problem with a different solution.
