Most of the time, a baby who hasn’t pooped in a while doesn’t need medication or a doctor’s visit. Simple changes to feeding, a few gentle physical techniques, and knowing what’s actually normal can save you a lot of worry. Here’s what works and when to be concerned.
What “Normal” Actually Looks Like
Before trying to fix anything, it helps to know whether there’s actually a problem. In the first three months, breastfed babies typically have about three soft bowel movements a day, and formula-fed babies average two to three. But the range is enormous: a breastfed baby can poop after every feeding or go five to seven days between bowel movements, and both can be perfectly fine.
Frequency alone isn’t the issue. Constipation is about consistency and comfort, not the calendar. A baby who poops every four days but produces soft stool without straining isn’t constipated. A baby who poops daily but produces hard, pellet-like stool and cries during the process likely is. The signs to watch for include abdominal bloating, hard or painful stools, changes in appetite, frequent fussiness that seems related to stomach discomfort, and blood in the stool or diaper from straining.
Physical Techniques That Help
These are the fastest, safest things you can try right now, no supplies needed.
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 digestive system and can encourage a bowel movement. Do it slowly and gently for 30 seconds to a minute at a time, and repeat a few times throughout the day.
Tummy massage: With your baby on their back, use two or three fingers to massage their belly in a clockwise direction. Start from the lower right side of the belly (where the large intestine begins) and work toward the lower left (where the colon is). This follows the natural path of digestion and helps push things along. You can also gently twist your baby’s hips and legs from side to side, which encourages movement through the digestive tract.
Warm bath: A warm bath relaxes the abdominal muscles and can help your baby pass stool more easily. It also tends to calm a fussy baby, which helps because tension and crying can work against bowel movements.
Feeding Changes by Age
Under 4 Months
At this age, your baby’s diet is exclusively breast milk or formula, so your options are limited. If you suspect constipation, you can try offering 1 ounce of prune, apple, or pear juice mixed with 1 ounce of water, once or twice a day. The natural sugars in these juices draw water into the intestines and soften stool. Don’t give plain water to babies under 6 months, as their kidneys aren’t ready for it, and too much can dilute important nutrients.
Formula-fed babies are more prone to constipation than breastfed babies because formula is harder to digest. If your formula-fed baby is consistently struggling, the formula itself may be a factor worth discussing with your pediatrician. Sometimes a different formulation makes the difference.
4 to 6 Months
If your baby has started solids (or is getting close), fruits like prunes, pears, and apples are your best tools. Pureed versions of these fruits work well and are easy to introduce. You can also continue with small amounts of diluted juice from these same fruits if needed.
6 to 12 Months
Once your baby is 6 months old, you can start offering small amounts of water, around 4 to 8 ounces spread throughout the day. This extra hydration helps keep stool soft. At this age, you also have a wider range of high-fiber foods to work with: pureed or soft-cooked carrots, broccoli, green peas, pears, and berries all help keep things moving. If your baby has recently started eating solid foods and constipation appeared around that time, their body is simply adjusting to digesting new things. Increasing the fiber and water in their diet usually resolves it within a few days.
Foods That Can Make It Worse
Some common early foods are binding and can contribute to constipation. Rice cereal, bananas, and applesauce (despite apple juice being helpful, the fiber composition of applesauce works differently) are frequent culprits. If you notice harder stools after introducing a new food, try pulling it back and replacing it with one of the softer-stool-promoting fruits and vegetables above. You don’t need to eliminate binding foods entirely, just balance them with higher-fiber options.
When Juice or Dietary Changes Aren’t Enough
If physical techniques and feeding adjustments haven’t helped after a few days, some parents consider glycerin suppositories. For children under 2, these require a doctor’s guidance, so don’t use them on your own for an infant. For toddlers aged 2 to 5, pediatric glycerin suppositories are available over the counter at a dose of one per day, but they shouldn’t be used for longer than a week without a doctor’s direction. They work by drawing water into the rectum and stimulating a bowel movement, usually within 15 to 60 minutes.
Suppositories are a short-term fix. If your baby needs them repeatedly, the underlying cause, whether dietary, related to formula, or something else, needs attention.
Signs That Need a Doctor’s Attention
Blood in the stool should always prompt a call to your pediatrician, even if it seems like a small amount from straining. For newborns and young infants, any suspected constipation is worth mentioning at your next visit (or sooner) because the causes can be different than in older babies. Beyond infancy, stools that are consistently large, hard, or painful to pass are a good reason to check in. Constipation paired with vomiting, refusal to eat, poor weight gain, or a visibly distended belly warrants a prompt visit rather than waiting for dietary changes to take effect.
