Most babies who seem constipated can be helped with simple changes at home: gentle movement exercises, small dietary adjustments, or a bit of extra fluid. Before trying anything, though, it helps to know whether your baby is actually constipated or just following a normal pattern that looks worrying.
What “Normal” Looks Like at Each Age
Babies poop on wildly different schedules depending on how they’re fed and how old they are. Breastfed newborns average about five bowel movements a day in their first month, dropping to around three a day by month two. Formula-fed newborns average about two a day in month one and closer to one or two by month two. Breastfed babies also tend to have looser, more liquid stools during the first three months.
Here’s the part that surprises many parents: after the first six weeks or so, some breastfed babies go several days, even a full week, without pooping and are perfectly fine. Breast milk is so efficiently absorbed that there’s sometimes very little waste. As long as the stool is soft when it does come and your baby seems comfortable, infrequent pooping alone isn’t a problem.
How to Tell If Your Baby Is Actually Constipated
Constipation in babies is defined more by how the stool looks and feels than by how often it comes. Pediatric guidelines consider a baby constipated if, for at least a month, they show two or more of the following:
- Two or fewer bowel movements per week
- Hard, pellet-like, or unusually large stools
- Signs of pain or straining during bowel movements (crying, arching, turning red)
- A large buildup of stool that you or a doctor can feel in the belly
Newborns often grunt, turn red, and strain even when passing normal soft stool. Their abdominal muscles are weak and they haven’t learned to coordinate pushing yet. If the stool that comes out is soft, that straining is not constipation.
Bicycle Legs and Tummy Massage
Two physical techniques are safe, free, and often surprisingly effective. You can use them anytime, though many parents find they work well about 30 minutes after a feeding.
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 contracts the abdominal muscles and puts gentle, rhythmic pressure on the intestines. Do this for a minute or two at a time, pausing if your baby seems uncomfortable.
Tummy massage: With warm hands, place your palms flat on your baby’s belly at or below the navel. Using a gentle paddling motion, stroke downward with alternating hands. Then switch to slow, circular strokes moving clockwise (this follows the direction of the intestines). One popular technique is the “I Love You” stroke: trace the letter I down your baby’s left side, then an L from their right side across the top of the belly and down the left, then an upside-down U from lower right, up and over, and down the left side. Finish by stroking gently downward a few times.
A Warm Bath Can Help
A warm bath relaxes the muscles around the abdomen and can sometimes get things moving on its own. The warm water eases tension, and many babies will have a bowel movement during or shortly after bath time. You can combine this with tummy massage for extra effect.
Fluids That Soften Stool
For babies under six months, breast milk or formula should be their only nutrition. But small amounts of certain fruit juices can act as a gentle, natural stool softener. Juices that contain sorbitol, a sugar alcohol that draws water into the intestines, are especially effective. Prune juice, pear juice, and apple juice all contain sorbitol.
For babies younger than six months, the recommended amount of prune juice is roughly 1 to 3 milliliters per kilogram of body weight, which can be diluted with an ounce or two of water. For a 12-pound baby, that works out to about 1 to 3 teaspoons. Start small and see how your baby responds before offering more.
Once your baby is between 6 and 12 months old, you can offer 4 to 8 ounces of water per day alongside their regular milk feeds. Extra fluid helps keep stool soft, especially once solid foods are in the picture.
Foods That Get Things Moving
If your baby has started solids (typically around six months), the foods you choose can make a real difference. The classic “P fruits” are popular for a reason: pureed prunes, pears, peaches, and plums all have fiber and natural sugars that help draw water into the stool. Green peas are another good option.
On the flip side, some common early foods can contribute to constipation. Rice cereal, bananas, and large amounts of dairy (like yogurt or cheese) tend to firm up stool. If your baby is backed up, try swapping rice cereal for oat or barley cereal and favoring the high-fiber fruits and vegetables for a few days.
Formula Adjustments Worth Considering
Formula-fed babies are more prone to constipation than breastfed babies, and the type of formula matters. Research has found that formulas containing prebiotics (specific types of plant-based fiber), partially broken-down whey protein, and a fat structure that mimics breast milk tend to produce softer stools in constipated infants. In one clinical trial, significantly more babies on a formula with these ingredients had soft stools compared to those on a standard formula.
If your formula-fed baby is regularly producing hard, pellet-like stools, switching to a formula marketed for digestive comfort or “sensitive” digestion may help. These typically contain the prebiotic and protein modifications shown to soften stool. Talk to your pediatrician before switching, especially if your baby is under three months old or has other health concerns.
What About Glycerin Suppositories?
Glycerin suppositories are sometimes suggested as a quick fix, and they do work by lubricating the rectum and stimulating a bowel movement. But they come with risks worth knowing about. Possible side effects include irritation of the rectal lining and, in rare cases, small amounts of bleeding. They’re best treated as an occasional rescue tool rather than a regular solution, and you should check with your pediatrician before using one, especially for babies under six months.
Rectal thermometer stimulation (gently inserting a lubricated rectal thermometer) works on a similar principle and carries similar risks. It can become habit-forming in the sense that the baby’s body may start to rely on the stimulation rather than learning to pass stool independently.
Signs That Need Medical Attention
Most infant constipation resolves with the home strategies above. But certain signs suggest something more is going on. Red streaks in the stool or blood on the diaper, a visibly swollen or tender belly, vomiting along with constipation, or constipation that started in the very first days of life (which can signal a structural issue) all warrant a call to your pediatrician. Severe constipation that doesn’t respond to dietary changes and physical techniques within a week or two is also worth getting checked out, since your doctor can rule out less common causes and recommend safe treatments appropriate for your baby’s age.
