For a constipated baby, the best first steps are gentle physical techniques like bicycle legs and tummy massage, followed by small amounts of fruit juice if your baby is old enough. Most cases resolve with these simple interventions, but what works depends on your baby’s age and whether they’ve started solid foods.
Before trying anything, though, it helps to know whether your baby is actually constipated or just on the slower end of normal.
What “Normal” Actually Looks Like
Baby poop frequency varies wildly, and many parents worry about constipation when their baby’s pattern is perfectly healthy. Normal ranges from several poops a day to one poop every several days. Breastfed babies generally poop more often than formula-fed babies, and younger babies go more frequently than older ones.
Here’s the part that surprises most parents: a baby who’s been pooping normally for a few weeks can go 5 to 7 days without a bowel movement and still be fine, as long as they’re eating well and gaining weight. The real signs of constipation aren’t about frequency alone. Look for hard, pellet-like stools, visible straining and discomfort that lasts more than a few minutes, a firm or distended belly, or a baby who fusses and arches their back during bowel movements. If the stools come out soft, your baby probably isn’t constipated, even if they grunt and turn red while pushing.
Tummy Massage and Bicycle Legs
Physical techniques are the safest, gentlest first option for any age. They work by stimulating the muscles of the intestines and helping move gas and stool along.
Bicycle legs: Lay your baby on their back and gently move their legs in a cycling motion, as if they’re pedaling a tiny bike. This puts gentle pressure on the abdomen and can help get things moving.
The “I Love You” massage: With your baby on their back, use gentle pressure to trace three shapes on their belly. First, draw a straight line down the left side of their belly (that’s the “I”). Then draw an upside-down “L” going from your left to your right across the upper belly and down (that’s “Love”). Finally, trace an upside-down “U” shape from the lower right, up, across, and down the left side (that’s “You”). Say “I love you” as you go, which helps you remember the pattern and keeps the mood calm.
Knee-to-tummy press: Place your hands on your baby’s calves, including the knees, and gently push both legs together toward their tummy. Hold for three to five seconds, release, and repeat three to five times. This mimics the squatting position that naturally helps with bowel movements.
Try these techniques twice a day for about two weeks to see results. A warm bath before the massage can help relax your baby’s abdominal muscles and make the whole process more effective.
Juice and Extra Fluids
If your baby is 6 months or older, small amounts of 100% fruit juice can act as a natural stool softener. The sugars in certain juices draw water into the intestines, which helps soften stool and get things moving. Prune, pear, and apple juice work best for this purpose.
For babies 6 to 12 months, offer up to 1 ounce (30 mL) of undiluted juice between feedings, up to a maximum of 4 ounces (125 mL) in 24 hours. Start small and increase gradually. For children over 1 year, keep juice to no more than half a cup per day.
Around 6 months, you can also start offering small sips of water in an open or sippy cup. The American Academy of Pediatrics suggests 4 to 8 ounces per day at this age. Extra fluid helps keep stool soft, especially once your baby starts eating solid foods.
Solid Food Adjustments
If your baby has started solids, what they eat makes a big difference. Some common early foods like bananas, rice cereal, and applesauce can actually worsen constipation. Shift toward higher-fiber options instead.
Good choices include pureed pears, prunes, peaches, and plums (the “P fruits” are easy to remember). For vegetables, try pureed peas, broccoli, and carrots. If your baby is eating finger foods, soft-cooked chunks of these same foods work well. Oatmeal tends to be a better cereal choice than rice cereal for babies who struggle with hard stools.
Formal fiber intake guidelines don’t exist for babies under 1 year, so there’s no specific target to hit. The goal is simply to include more fruits and vegetables in their daily rotation and cut back on the binding foods.
What About Switching Formula?
If your formula-fed baby is consistently constipated, you may wonder whether the formula itself is the problem. One common concern is iron, but there’s no scientific evidence that the iron in infant formula causes constipation. Don’t switch to a low-iron formula for this reason.
Goat milk-based formulas, which received AAP approval in 2023, have gained popularity partly because some parents report improved stooling and better digestive tolerance. Partially hydrolyzed or extensively hydrolyzed protein formulas, sometimes marketed for sensitive tummies, don’t have strong evidence supporting their use specifically for constipation. If you’re considering a formula switch, talk to your pediatrician first rather than experimenting on your own.
Glycerin Suppositories and Laxatives
When home remedies aren’t enough, glycerin suppositories are often the next step. These small, slippery inserts go into the rectum and draw water into the stool, triggering a bowel movement within minutes to an hour. For children under 2, they should only be used under a doctor’s guidance. For children 2 to 6, the standard dose is one suppository once daily, and they shouldn’t be used for longer than one week without medical direction.
Osmotic laxatives (the kind that draw water into the intestines to soften stool) have been studied in children under 2 and found to be effective, with no serious side effects reported. The most common issue was diarrhea, which resolved when the dose was lowered. However, the pediatric preparation is typically labeled for children over 2, so using it in younger babies requires a doctor’s recommendation and dosing guidance.
These are not tools to reach for casually. Try the physical techniques, dietary changes, and juice first. If those don’t work after a week or two, that’s when it’s time to call your pediatrician for next steps.
Warning Signs That Need Medical Attention
Most infant constipation is harmless and temporary, but a few red flags call for a prompt visit to your pediatrician. Blood in the stool always warrants a call. If your newborn (under a few weeks old) seems constipated, contact your doctor rather than trying home remedies, since very young babies who aren’t stooling may have an underlying issue that needs evaluation. Persistent vomiting, a visibly swollen or hard abdomen, refusal to eat, or stools that are consistently large and painful to pass also deserve professional attention.
