Everything you need to know about infant constipation.

It has been days since you last changed a dirty diaper. Naturally, you are starting to worry. While you might secretly enjoy the break from poop-stained clothing, the panic is setting in. Is your baby okay? Are they backed up?

We have all been there. You find yourself obsessing over bowel movements, wondering if your little one is uncomfortable or in pain.

Knowing the difference between a normal pause in pooping and actual constipation can save you a lot of stress. We consulted the experts to break down exactly how long breastfed and formula-fed babies can go without pooping. We will also cover the real signs of constipation, how to treat it at home, and when you need to call the pediatrician.

Key Takeaways

  • Normal varies: Infant bowel movement frequency changes drastically based on age and diet; there is no single “right” schedule.
  • Breastfed babies: It is normal for them to poop after every feed or go over a week without a single bowel movement once they pass the six-week mark.
  • Formula-fed babies: These infants typically poop once a day or every other day, but their stools are generally firmer than breastfed babies.
  • Watch the consistency: Hard, dry, pebble-like stool is a bigger indicator of constipation than frequency.


How Often Should My Baby Poop?

Breastfed Babies

“Normal” looks different for every exclusively breastfed baby. Your little one might poop after every single feeding, or they might go days (or even a week or two) without a single poop once they are older than six weeks.

During the first 24 hours of life, your baby’s poop will be a black, tarry substance called meconium. Breastfed babies should have at least three bowel movements within their first 24 hours. As colostrum changes to mature milk, your baby’s stools transition from black to greenish, and finally to yellow, seedy, and loose (1).

Colostrum acts as a natural laxative. This means exclusively breastfed babies usually poop frequently during those early newborn days.

Take Note

After the first six weeks, bowel movements often decrease. Exclusively breastfed babies over two or three months old can easily go one or two weeks without a poopy diaper.

Breastmilk is perfect for the human body. It is absorbed so efficiently that there is very little “waste” left to leave your baby’s body. They use almost all those nutrients to grow, leaving you with fewer messy diapers to change.

Formula Fed Babies

Baby formula is slightly harder to digest than breastmilk. Consequently, it is typical for formula-fed babies to have fewer bowel movements than breastfed babies during the newborn stage. A formula-fed newborn typically poops three to five times a day.

After the first six weeks, formula-fed babies typically settle into a routine of one bowel movement every day or every other day.

Common Causes of Infant Constipation

If your baby is truly backed up, there is usually a specific culprit. Here are common reasons for newborn constipation:

  • Powdered formula: Formula often creates firmer, bulkier stools. This can happen if the ratio of powder to water is incorrect.
  • Dietary changes: Switching from breastmilk to formula, or even changing formula brands, can temporarily disrupt your baby’s digestive system.
  • Introduction of solids: When babies start eating solid foods (around 6 months), their poop often becomes harder and less frequent as their gut adapts.
  • Allergy or intolerance: Your baby might have an intolerance to the milk protein found in formula or passed through breastmilk.
  • Dehydration: If a baby lacks fluid, their body absorbs moisture from the waste in their intestines, creating hard, dry stools.
  • Physical issues: Rarely, physical abnormalities like a tight anus or bowel obstruction can cause issues.
  • Medical conditions: In very rare cases, conditions like hypothyroidism or Hirschsprung’s disease affect the large intestine and make passing stool difficult (2).

Signs of Infant Constipation

Frequency is not always the best indicator since babies have such different schedules. Instead, look at the consistency of the stool and your baby’s behavior. Here are the major signs your baby is constipated (3):

  1. Painful passing: The baby cries in obvious pain when stool is actually coming out.
  2. Tight belly: The stomach feels firm or hard to the touch.
  3. Hard stool: The poop is dry, hard, and looks like rabbit droppings or pellets.
  4. Loss of appetite: The baby is eating less than usual due to discomfort.
  5. Bloody stool: Small streaks of blood caused by tiny tears (fissures) from passing hard stool.

Take Note

Note: Babies often grunt, turn red, and strain when pooping because they lay flat and cannot use gravity to help. This is often “infant dyschezia,” not constipation, provided the poop comes out soft eventually.

Relieving Baby’s Constipation

If your baby is fussy, has a firm abdomen, and is passing hard pellets, they likely need help. Here are some effective ways to get things moving:

how to relieve baby constipation

  • Bicycle legs: Place your baby on their back and move their legs in a circle, as if they are pedaling a bike. This motion relieves belly pressure.
  • Warm bath: A warm soak or a warm washcloth on the belly helps relax tense muscles.
  • Change formula: Your baby might need a sensitive stomach formula or a different brand. Consult your doctor before switching.
  • Dietary adjustments: If breastfeeding, try eliminating dairy from your diet. If the baby is on solids, offer “P” fruits like pears, plums (prunes), and peaches.
  • Tummy massage: Gently massage their tummy in a clockwise motion near the navel. Use baby lotion or coconut oil to help your hands glide.

If home remedies fail, consult your pediatrician about these options:

  • Rectal stimulation: Taking a rectal temperature can sometimes stimulate the bowels.
  • Fruit juice: A small amount of prune, apple, or pear juice (usually 1 oz per month of age) draws water into the stool.
  • Glycerin suppositories: These can lubricate the rectum but should only be used under a doctor’s direction.

Take Note

Never use mineral oil, enemas, or stimulant laxatives on a baby unless explicitly told to do so by a medical professional.

When Should I Worry?

Call your doctor immediately if home remedies do not work or if you spot these warning signs:

  • Blood: Bloody or black stool.
  • Dehydration: Fewer wet diapers, dry mouth, or no tears when crying.
  • Illness: Fever or persistent vomiting.
  • Refusal to eat: The baby will not breastfeed or take a bottle.
  • Vomit color: Green or yellow spit-up or vomit.
  • Weight loss: The baby is losing weight or failing to gain.
  • Severe pain: Inconsolable crying for long periods.

Warning

If a baby is vomiting bile (green/yellow) and has a swollen abdomen, go to the emergency room immediately. These are signs of intestinal obstruction, which is life-threatening (4).

Baby Constipation FAQs

How Long Is It Ok for a Baby to Be Constipated?

For breastfed babies older than six weeks, it is safe to go more than a week without pooping as long as the stool is soft when it comes out.

For formula-fed babies, going more than 3 to 5 days without a bowel movement is rare and may warrant a check-up. However, if the baby seems happy and is eating well, a delay isn’t always an emergency.

What Foods Make a Baby Poop?

Foods high in fiber and natural sugars help draw water into the gut. The “P” fruits are your best friends here: pears, peaches, plums, and prunes.

You can offer these as purees or diluted juice. Chia seeds and flax seeds mixed into food can also work wonders for older babies eating solids.

How Do You Massage a Baby to Poop?

Lay your baby on their back. Using your fingertips, gently massage the abdomen in a clockwise circular motion around the navel.

Do this for about 3 to 5 minutes. The clockwise direction follows the natural path of the large intestine, helping push gas and stool toward the exit.

Does Tummy Time Help With Constipation?

Yes, tummy time helps. Placing your baby on their belly puts gentle pressure on the abdomen.

This pressure, combined with the baby’s wiggling and movement, stimulates the digestive system and can help eliminate excess gas and move stool along.

How Often Can I Give Mommy’s Bliss Baby Constipation Ease?

Follow the package directions strictly, which usually recommend no more than two doses in a 24-hour period.

Remember that supplements like this are temporary aids, not permanent fixes. If your baby needs daily medication to poop, you need to speak with your pediatrician to find the root cause.

How Do Hospitals Treat Constipation in Babies?

If a hospital visit is necessary, doctors may use a glycerin suppository or an enema to clear the blockage.

They will also check for dehydration and physical obstructions. In most cases, they will provide a plan for maintaining soft stools at home using diet or mild stool softeners like polyethylene glycol.

Do Iron Supplements Cause Constipation in Babies?

It is a common belief that iron causes constipation, but studies show that the iron in iron-fortified formula usually does not cause bowel issues.

However, standalone iron drops supplements (prescribed for anemia) can sometimes cause harder stools. If you suspect the drops are the issue, talk to your doctor about dosage or timing; do not stop the supplement without medical advice.


The Poop Scoop

If your baby seems painful, has hard, pellet-like poops, or strains constantly without success, they likely need a helping hand. Try warm baths, tummy massages, bicycling their legs, or a splash of pear juice.

Call the doctor if home remedies fail, if you see blood, or if your baby is vomiting.

However, if your baby is simply popping less frequently but remains happy, eating well, and producing soft stool when they finally go, take a deep breath. Enjoy the break from the diaper changing station!
