What to Do If Your Newborn Is Constipated

Most newborns who seem constipated aren’t, and that’s the first thing worth knowing. True constipation in newborns is uncommon, especially in breastfed babies. Before trying any remedy, you need to figure out whether your baby is actually constipated or just learning how to poop. The distinction matters because the solutions are completely different.

Straining Doesn’t Always Mean Constipation

Newborns often grunt, turn red, cry, and strain for 10 to 30 minutes before producing a bowel movement. This looks alarming, but it has a name: infant dyschezia. It happens because babies haven’t yet learned to coordinate two things at once, relaxing their pelvic floor while pushing with their abdomen. They’re essentially working against their own muscles.

The key difference is what comes out. If your baby strains and then passes soft, pasty, or seedy stool, that’s dyschezia, not constipation. The poop itself is normal; the process of getting it out is what your baby is still figuring out. This resolves on its own, usually within a few weeks, as your baby’s coordination matures. No treatment is needed, and rectal stimulation can actually delay the learning process by doing the work for them.

If the stool is hard, dry, pellet-like, or unusually large, or if there’s blood on it, that points to actual constipation.

What Counts as Real Constipation

Constipation in infants is defined by stool consistency and difficulty, not frequency. A baby who poops every three days but passes soft stool without distress is not constipated. A baby who poops daily but produces hard, painful stools may be.

The clinical definition is a delay or difficulty in defecation lasting two or more weeks that causes significant distress. Signs include extremely hard stools, large stools, visible pain during bowel movements, and a baby who seems to be actively withholding rather than pushing. Stool frequency varies widely among healthy newborns. Some poop after every feeding, others go two to three days between bowel movements. Breastfed babies tend to poop more often than formula-fed babies, but both ranges are normal.

Gentle Physical Techniques to Try First

If your baby’s stools are genuinely hard or they’re clearly struggling with more than just coordination, a few physical techniques can help move things along.

Bicycle legs: Lay your baby on their back and hold one foot or leg in each hand. Slowly move their legs in a cycling motion, bending one knee toward their belly while extending the other leg. This gentle compression on the abdomen can help stimulate the bowel. Watch your baby’s reaction and stop if they seem uncomfortable.

Tummy massage: Place your baby on their back and use gentle pressure on their belly. One effective method is the “I love you” technique: trace an upside-down letter I on the left side of your baby’s belly, then an upside-down L starting on the left and moving across, then an upside-down U crossing over the whole tummy. Another option is to massage slowly in a clockwise direction, following the natural path of the intestines. You can also use the sides of your hands to stroke gently from the rib cage down to the pelvis, alternating hands in a paddling motion.

A warm bath before trying these techniques can help relax your baby’s muscles and make everything more effective.

Fruit Juice for Babies Over One Month

For babies older than one month who are exclusively breastfed or formula-fed, small amounts of fruit juice can help soften stools. The American Academy of Pediatrics recommends 1 ounce (30 mL) per month of age per day, up to a maximum of 4 ounces. So a two-month-old would get up to 2 ounces daily.

Pear and apple juice work well for younger babies. After three months, prune juice is also an option and tends to be the most effective. The natural sugars in these juices draw water into the intestines, which softens the stool. This isn’t a daily habit to maintain long-term; it’s a short-term tool for relieving a bout of constipation.

Formula Changes That May Help

If your baby is formula-fed and regularly constipated, the formula itself could be a factor. Some formulas are processed to break down proteins into smaller molecules, making them easier to digest. Others contain added prebiotics that support softer stools.

Babies with signs of dairy sensitivity or food allergies are more likely to have digestive trouble, including constipation. If your baby also has excessive gas, skin rashes, or unusual fussiness, switching to a formula with different protein sources may improve digestion. Talk to your pediatrician before switching, since they can recommend a specific type based on your baby’s symptoms rather than having you guess your way through the formula aisle.

Glycerin Suppositories as a Last Resort

Glycerin suppositories are sometimes used for infant constipation, but they should not be your first move. A small sliver of a glycerin suppository can help a baby pass a stubborn stool by drawing water into the rectum and triggering a bowel movement. These should not be used more than once every 12 to 24 hours.

They should never be used if your baby is dehydrated or has rectal bleeding. And they’re not effective as a preventive measure. Research on preterm and low-birthweight infants found that routine glycerin suppositories didn’t speed up feeding tolerance or improve outcomes. These are a tool for occasional relief, not a regular solution. If your baby needs them repeatedly, the underlying cause needs attention.

How to Spot Dehydration

Hard stools and dehydration often go hand in hand. When a baby isn’t getting enough fluid, the body pulls water from the stool, making it harder and more difficult to pass. From day six onward, your newborn should produce at least six wet diapers in a 24-hour period. Many babies produce eight to ten.

If your baby has fewer than six wet diapers a day, goes more than eight hours without urinating, or has a dry mouth or sunken soft spot on their head, dehydration may be contributing to the constipation. For breastfed babies, this usually means increasing feeding frequency. For formula-fed babies, make sure you’re mixing formula exactly as directed, since over-concentrating it reduces the water content.

Signs That Need Medical Attention

Blood in your baby’s stool always warrants a call to your pediatrician. It can result from a small anal fissure caused by passing hard stool, which is usually minor, but it can also signal something that needs evaluation.

Other red flags include a visibly distended or tight abdomen, vomiting (especially green or bile-colored), refusal to feed, and constipation that starts in the first few days of life before meconium has fully passed. Constipation present from birth can occasionally indicate an anatomical issue or a condition affecting the nerves of the bowel, which your pediatrician will want to rule out with a physical exam.
