For newborns under one month old, you should not give any over-the-counter remedies without guidance from your pediatrician. For babies over one month old who are on breast milk or formula only, small amounts of fruit juice are the most common first-line option. But before reaching for any remedy, it’s worth making sure your baby is actually constipated, because what looks like a problem often isn’t one.
What Newborn Constipation Actually Looks Like
New parents frequently worry when their baby hasn’t pooped in a day or two, but infrequent pooping alone isn’t constipation. Babies who have been pooping normally in their first couple of weeks can go as long as five to seven days between bowel movements without anything being wrong, as long as they’re eating and growing well.
True constipation is defined by stool that is hard, dry, and difficult to pass. Think small pellets or firm, pebble-like lumps. If your baby strains, turns red in the face, or cries while trying to pass a bowel movement but the stool comes out soft, that’s normal. Babies are still learning to coordinate the muscles involved in pooping, and grunting or straining with soft stool is not constipation.
The key question isn’t “how often?” but “how hard?” If your baby’s stool is soft and comes out without much trouble, the frequency doesn’t matter much. If the stool looks like firm pellets or your baby seems to be in genuine distress trying to pass it, that’s when to consider intervention.
Fruit Juice for Babies Over One Month
For babies older than one month who are exclusively on breast milk or formula, fruit juice is the standard home remedy pediatricians recommend. Pear juice and apple juice work well because they contain sugars that draw water into the intestines, softening stool naturally. After three months of age, prune juice is also an option and tends to be the most effective.
The recommended amount is one ounce per month of age per day. So a two-month-old would get two ounces, a three-month-old three ounces, up to a maximum of four ounces daily. You can offer this between feedings, either straight or mixed with a small amount of water. This isn’t a daily dietary addition; it’s a short-term tool to get things moving. Once your baby is pooping comfortably again, stop the juice.
Glycerin Suppositories
Glycerin suppositories are sometimes suggested for infant constipation, but the labeling on pediatric glycerin suppositories states that children under two years old should only use them under a doctor’s direction. These are not something to try on your own with a newborn. If juice hasn’t worked and your baby seems uncomfortable, call your pediatrician before using a suppository. They can walk you through whether it’s appropriate and how to use one safely at your baby’s size and age.
What Not to Give
Corn syrup (Karo syrup) is an old home remedy that still circulates online and through family advice. Health authorities now recommend against it. The concern is that commercial corn syrup is no longer processed the same way it once was, and it may carry a risk of bacterial contamination that can be dangerous for infants. Honey carries the same risk and should never be given to babies under one year old.
Mineral oil, stimulant laxatives, and enemas are also off the table for newborns unless a doctor specifically prescribes them. Even “natural” or herbal remedies marketed for babies can contain ingredients that aren’t safe at this age.
Formula-Related Constipation
Formula-fed babies are more prone to constipation than breastfed babies because formula is harder to digest than breast milk. One of the most common and overlooked causes is incorrect formula preparation. Adding too much powder relative to water makes the mixture more concentrated, which can cause both constipation and dehydration. Always follow the exact measurements on the formula packaging, using the scoop that comes in the container and leveling it off rather than packing it.
If your baby is consistently producing hard stools on their current formula, your pediatrician may suggest trying a different brand or type. Some formulas are designed to produce softer stools. Don’t switch formulas on your own without checking in first, since frequent switching can sometimes make digestive issues worse.
Breastfed Babies and Constipation
True constipation is uncommon in exclusively breastfed babies. Breast milk is so efficiently absorbed that some breastfed infants simply don’t produce much waste, which can mean long gaps between bowel movements. This is normal as long as the baby is gaining weight and the stool, when it does come, is soft.
If a breastfed newborn hasn’t pooped in 24 to 48 hours during the early weeks, it may be a sign they’re not getting enough milk rather than a sign of constipation. This is especially relevant in the first few weeks when milk supply is still establishing. If your newborn seems hungry, isn’t gaining weight, or isn’t producing enough wet diapers alongside the missing stools, the issue is likely intake rather than constipation.
Simple Comfort Measures
Before trying juice or calling your pediatrician, a few physical techniques can help stimulate a bowel movement. Gently cycling your baby’s legs in a bicycling motion while they lie on their back can help move things along in the intestines. A warm bath can relax the abdominal muscles. Some parents find that gentle, clockwise belly massage (following the path of the intestine) helps as well.
These techniques won’t fix a structural problem, but they often provide enough stimulation to help a baby who is on the verge of pooping but struggling to coordinate the effort. They’re safe to try at any age and have no side effects.
Signs That Need Medical Attention
Blood in your baby’s stool always warrants a call to your pediatrician. In many cases it’s caused by a small anal fissure from passing hard stool, which isn’t dangerous, but it needs to be evaluated. A newborn who has never passed meconium (the dark, tarry first stool) within the first 48 hours of life needs immediate medical evaluation, as this can signal a bowel obstruction or other anatomical issue. Constipation paired with a swollen, firm belly, vomiting, or refusal to eat also needs prompt attention. These combinations can indicate something beyond simple functional constipation.
