Can Breastfed Babies Get Constipated?

Constipation in the breastfed baby is uncommon, although the introduction of solid foods can sometimes cause constipation. When it comes to a baby's stools, there is a broad range of normal.

So, How Often Should Your Baby Have a Bowel Movement?


Before Six Weeks

Dark, tarry stools are to be anticipated during the first few days; these stools are referred to as meconium. Colostrum, also known as "pre-milk", helps to clear meconium from the gut, and within a few days, the stools become yellowish-tan and soft. The stools will have a not-so-unpleasant kind of "porridge/popcorn or cheesy" smell to them. The consistency is usually compared to custard or mustard because it usually contains small seedy-looking bits.

After the meconium has been cleared from their systems, most babies will have two to five soft stools every 24 hours for the first six weeks of life. BUT - it is also normal for them to have more or less frequent bowel movements. As long as the baby has regular wet diapers (about six diapers every 24 hours) and is gaining weight, you don't need to worry about it. 

Be sure to breastfeed your baby on demand (at least eight times per day). Avoid pacifier use because this will replace valuable time at the breast. 

To ensure adequate milk intake, it is essential that your baby drinks more during the day if he/she is sleeping through at night. 


After Six Weeks

After six weeks you may notice that your baby has fewer stools than before, sometimes only one bowel movement every ten days or longer; this is because breast milk is so easily absorbed. Again, it's also normal for them to have one stool after every feeding. Less frequent bowel movements should be easy to pass and soft. After the six week mark, your baby will be wetting about five diapers daily, but they should be considerably heavier than before; this is because your baby is now able to hold more urine in their bladder. 


Six Months Onwards

As soon as solids are introduced at about six months, your baby's digestive system will be working through many changes. The stools will start to smell stronger, and the color and consistency will change. You may find pieces of food in the stool that have not been digested. During this time babies often struggle with diarrhea or constipation when they are not tolerating a particular food well.

Any Iron-fortified, or cow's milk-based cereals and formulas are common constipation triggers in babies. Always breastfeed your baby before offering solids, and if your baby becomes constipated, try to breastfeed more often; breastmilk acts as a natural laxative. The frequency of bowel movements should increase when solid foods are introduced. Call your pediatrician if you believe your baby is constipated.

Foods that cause constipation in breastfed babies who have started solids:

  • Banana.
  • Rice cereal.
  • Carrots and squash.
  • Cow’s milk.


Breastfed Baby Constipation & the Mother's Diet
 

Could anything in a mother's diet cause constipation via her breast milk?  

Yes, caffeine can cause constipation in babies. So, try to limit your intake of chocolate, coffee, tea, and sodas, as the caffeine in these may pass through your breast milk to your baby. Your baby's liver is too immature to break down the caffeine; as a result, this could affect your baby's bowel movements. 

Cow's milk protein can also cause constipation in breastfed babies via the mother's milk. Sometimes a mother will need to eliminate all dairy from her diet. In the same way, a mother can eat prunes, and this may help to soften her baby's stools. 


Baby Constipation Signs

  • A constipated baby will have dry, hard stools. The stools may look like little pellets.
  • A baby with constipation may start vomiting.
  • The baby cries when straining to have a bowel movement. 
  • Refusing to breastfeed.
  • Baby seems weak.
  • Insufficient wet diapers.
  • Baby seems to have a dry mouth.
  • Weight loss or poor weight gain.
  • Disturbed sleep.
  • Excessive crying.
  • A hard, distended belly.
  • Drawing of their knees up towards their tummy.
  • Please contact your pediatrician if your baby has blood in their stool, or has a fever. 

"My baby is straining to poo and goes red in the face, but when it comes out, it is soft..."

Some babies may seem to struggle during bowel movements; this is normal and is partly their reaction to new sensations, which they are still growing accustomed to. They are also developing strength in their abdominal muscles needed to push the poo out. As long as the stool is soft, you don't need to worry. 


Medical Treatment for Constipation in Breastfed Babies

  • For babies younger than six months, try to avoid laxatives that need to be mixed with water as these might be difficult to feed to a breastfed baby and may interrupt the breastfeeding relationship. Oral laxatives, such as Lactulose or Senna are recommended, as well as Glycerine suppositories. 
  • For babies older than six months, ask your doctor about products containing polyethylene glycol (Miralax), which are more effective than other forms of constipation treatments. 


Natural Remedies for Constipation in Breastfed Babies

What can I do if my Baby is Constipated?

  • The best way to get a breastfed baby to poop is to breastfeed more frequently; breast milk is a natural laxative.
  • Never give your baby water unless instructed to do so by your doctor. Water can result in electrolyte imbalances. 
  • If your baby is older than six months, you can give him/her small amounts of pear, peach, plum, prune, or apricot. A well-known baby constipation remedy is apple juice; it can be given twice a day to soften the stools. 
  • A warm bath followed with a tummy massage can help to "get things moving." 
  • Move your baby’s legs in circular motions; this is especially helpful in constipated infants and those with gas.
  • If you find that the stool is sticking out and hurting your baby, you can smear some coconut oil around, and a little on, the inside of the anus, to help the feces glide out. 

If your baby has repeated episodes of constipation, you should see your pediatrician.

Newborn Constipation Formula Fed

by Heather (Jamaica)

I have a 6weeks old premature baby boy. He is on formula and iron because I'm not producing enough milk. 

I realize that he has a problem passing his stool on his own, so I assist by giving massage and using the q-tip. I'm concerned. Advise as to what I can do, other than what I am doing.

Constipation and Formula

Hi, Heather. Many times moms have found that if they change the type of formula they give their babies, constipation goes away. 

Why do you say your milk supply is low? 

Newborn Constipation Poop

by Anonymous

My baby is a week old, and her poop is hard, and she has had 2 of these today! She is formula fed, is this normal? Or should I panic?

Newborn Constipation 

by Tracy 

Hey! Have you thought of changing the formula? How was baby's poop before this? How often does your baby have a bowel movement? Does it look like your baby is in pain?

Average frequency is between 1 and 5 poops per day; this is for a formula fed baby for the first couple of weeks. The poo should be soft.

If the baby is in pain or poops less than once per day, you need to see your pediatrician. (this advice is only for newborn formula fed babies)

Breastfed Baby Constipated

by Rachel (Minnesota)

My baby is four days old and is breastfed. She is in the low levels of jaundice, and our doctor said to stick to just breastfeeding. 

She's been feeding frequently daily and has wet diapers, but she hasn't had a bowel movement in over 24 hours, but less than 48.

I'm anxious. My baby is gassy and seems to try to poop, but cries and fusses a lot. Is there anything I can do to help her? And when should I be worried about her poop, if she doesn't go still?

Breastfed Newborn Constipation

By Tracy

Hi Rachel, I would suggest that you breastfeed as much as possible. Let your baby comfort feed during the day as well. Breast milk is a natural laxative and will help clear jaundice as well. Have your doctor keep an eye on baby’s weight gain and count of wet nappies.

Babywearing can help reduce gas symptoms and will comfort your baby. You can keep your baby in a sling during the day, with as much skin to skin contact; this will also increase the time your baby spends at the breast.
