Most babies can get relief from constipation with a combination of gentle physical techniques, small dietary changes, and patience. The right approach depends on your baby’s age and whether they’ve started solid foods yet. Before jumping into fixes, it helps to know what constipation actually looks like in a baby, because irregular pooping alone isn’t always the problem.
What Constipation Actually Looks Like
Babies have wildly different pooping schedules. Some go after every feeding, others go once every two or three days. Breastfed babies tend to poop more often than formula-fed babies, but frequency alone doesn’t mean much. The real signs of constipation are about consistency and behavior, not just timing.
Your baby is likely constipated if you’re seeing at least two of these patterns over a period of a few weeks: fewer than two bowel movements per week, hard or pellet-like stools, visible straining or pain during bowel movements, or unusually large stools. It’s normal for babies to grunt and turn red while pooping. That’s just them figuring out how to coordinate their muscles. But if the straining is paired with hard, dry stools and your baby seems genuinely uncomfortable, that’s constipation.
A general rule: if your baby hasn’t pooped in four days, it’s worth calling your pediatrician even if they seem fine otherwise.
Physical Techniques That Help
For babies of any age, gentle movement and massage can stimulate the digestive system and get things moving. These are safe to try as a first step.
Bicycle legs: Lay your baby on their back and gently move their legs in a cycling motion, as if they’re pedaling a tiny bicycle. This helps move gas through the intestines and can encourage a bowel movement. There’s no set number of reps. Just do it gently for a minute or two and see how your baby responds.
Tummy massage: A technique called the “I Love You” massage follows the path of the large intestine. With your baby on their back, use gentle pressure to trace a line straight down the right side of their belly (the letter I). Then trace an L shape, going across the top of the belly from left to right and down the right side. Finally, trace an upside-down U, starting at the lower left of the belly, going up, across the top, and down the right side. Use a small amount of baby oil or lotion to reduce friction. You can do this daily or just when your baby seems uncomfortable.
A warm bath can also help relax the abdominal muscles. Some parents find that placing their baby in warm water before a massage makes the whole process more effective.
Dietary Fixes for Babies on Solids
If your baby is six months or older and eating solid foods, diet is your most powerful tool. Certain fruits act as natural laxatives because they contain sorbitol, a sugar alcohol that draws water into the intestines and softens stool. The easiest ones to remember are the “P fruits”: prunes, pears, and peaches. Pureed prunes are especially effective and can be mixed into oatmeal or other foods your baby already eats.
Other high-fiber options include peas, sweet potatoes, and barley cereal. If your baby has recently started solids and the constipation began around the same time, consider whether they’re eating a lot of binding foods like bananas, white rice cereal, or applesauce. Swapping rice cereal for oat or barley cereal can make a noticeable difference.
For babies over 12 months, a small amount of prune, pear, or apple juice can help. These juices contain sorbitol that increases the water content of stools. Limit juice to no more than 4 ounces per day for toddlers ages one through three. The American Academy of Pediatrics recommends against giving juice to babies under 12 months unless a doctor specifically suggests it for constipation relief.
Hydration Matters More Than You Think
For babies under six months who are exclusively breastfed or formula-fed, extra water isn’t recommended. Breast milk and properly mixed formula provide all the hydration they need. If your baby is formula-fed, double-check that you’re following the mixing instructions on the package exactly. Adding too much powder relative to water makes the formula more concentrated, which can cause both constipation and dehydration.
Once your baby is six months old and eating solids, you can offer small sips of water with meals. About 2 to 3 ounces at a time is appropriate. The goal isn’t to replace breast milk or formula but to add a little extra fluid that helps keep stools soft. Don’t overdo it, since too much water can fill up a small stomach and interfere with the nutrition they get from milk and food.
What About Suppositories and Laxatives
Glycerin suppositories are sometimes used for quick relief, but over-the-counter products are generally labeled for children two and older. For babies under two, you should only use them if your pediatrician recommends it and tells you the correct size and frequency.
An osmotic laxative (the active ingredient in MiraLAX) works by drawing water into the intestines to soften stool. A small study of 28 infants found it relieved constipation in nearly all of them with minimal side effects, mostly just temporary loose stools or extra gas. However, it’s not approved for infants without a doctor’s guidance, and the research in very young babies is still limited. If home remedies aren’t working after a few days, your pediatrician can advise whether a laxative is appropriate and what dose to use for your baby’s weight.
Breastfed vs. Formula-Fed Babies
True constipation is uncommon in exclusively breastfed babies. Breast milk is very efficiently absorbed, so some breastfed babies go several days between bowel movements without being constipated at all. As long as the stool is soft when it does come, infrequent pooping in a breastfed baby is usually normal.
Formula-fed babies are more prone to constipation. The composition of formula, especially iron-fortified varieties, can produce firmer stools. If your formula-fed baby is consistently constipated, talk to your pediatrician about whether a different formula might help. Some formulas are designed to produce softer stools. Never water down formula beyond the instructions to try to soften stool, as this dilutes the nutrition your baby needs and can be dangerous.
Signs That Need Medical Attention
Most infant constipation is functional, meaning there’s no underlying disease causing it. But certain red flags point to something more serious. Contact your pediatrician promptly if you notice blood in the stool along with a fever, if your baby is consistently not gaining weight, or if constipation started in the first few weeks of life (especially if your newborn didn’t pass their first stool within the first 48 hours after birth). A sacral dimple or tuft of hair at the base of the spine, while often harmless, can occasionally signal a nerve issue that affects bowel function and is worth mentioning to your doctor.
For the vast majority of babies, constipation is temporary and responds well to the combination of tummy massage, bicycle legs, and dietary adjustments once solids are in the picture. If you’ve tried these approaches for more than a week without improvement, that’s a reasonable point to check in with your pediatrician for next steps.
