Breastfed Babies and Constipation: What Parents Need to Know - Pediatrics

Can breastfed babies also experience constipation?


My baby has been having irregular bowel movements, about once every six days.
Although she is active, I am still very worried.
Could it be because I have been eating too much spicy or hot food? My older child was breastfed as well and did not have this issue, and had many bowel movements.
I read online that there are records of babies going up to 20 days without a bowel movement, but my baby seems to be holding it in, as she keeps passing very foul-smelling gas.
Today, I tried using a cotton swab to stimulate her anus, which resulted in a large amount of mushy stool, indicating that she is not constipated but rather has stool backed up in her little belly.
I am sure she must be uncomfortable.
What should I do? Should I change my diet? Is it bad to frequently stimulate my baby's anus to help her have a bowel movement? Could this cause her anal sphincter to relax? Thank you for your help, doctor!

Hello: The characteristics of breast milk stools can vary significantly; some infants may have multiple bowel movements in a day, while others may only have one every few days.
This is because the baby absorbs the milk completely, and the excess fluid is excreted through urine, which may result in fewer bowel movements over several days.
If there is no bowel movement after five to seven days, you can use a cotton swab to stimulate the rectum.
There is no need to worry about structural relaxation.
However, if there are concerns, a physician should evaluate the situation, as some infants may have a tight anal structure that requires assessment.

Breastfeeding is widely recognized for its numerous benefits, both for the baby and the mother. However, concerns about constipation in breastfed infants can arise, particularly when parents notice changes in their baby's bowel habits. In your case, your baby is having bowel movements every six days, which is concerning, especially since you mentioned that your older child did not experience this issue while breastfeeding.
First, it’s important to understand that breastfed babies can have a wide range of normal when it comes to bowel movements. Some breastfed infants may go several days without a bowel movement, and this can be completely normal, especially if they are otherwise healthy, active, and feeding well. Breast milk is highly digestible, and many babies absorb most of it, leading to less waste. However, if your baby is showing signs of discomfort, such as excessive gas or straining, it may indicate constipation.

Constipation in infants can be influenced by several factors, including dietary changes, hydration levels, and the baby’s overall health. Since you mentioned that your baby is experiencing discomfort and has not had a bowel movement in several days, it’s crucial to address this. Here are some steps you can take:
1. Dietary Adjustments: While breastfeeding, your diet can influence your baby's digestion. If you suspect that your diet might be contributing to your baby's constipation, consider incorporating more fiber-rich foods into your meals, such as fruits, vegetables, and whole grains. Additionally, ensure you are staying well-hydrated, as this can also affect your milk supply and the consistency of your milk.

2. Tummy Time and Movement: Encourage tummy time and gentle movement for your baby. This can help stimulate their digestive system. You can also try bicycle legs, where you gently move your baby's legs in a cycling motion to help relieve gas and encourage bowel movements.

3. Warm Baths: A warm bath can help relax your baby’s abdominal muscles and may stimulate a bowel movement. The warmth can provide comfort and help ease any discomfort they may be feeling.

4. Gentle Stimulation: While you mentioned using a cotton swab to stimulate the rectum, it's essential to do this sparingly. Overstimulation can lead to dependency, where the baby may rely on this method to have a bowel movement. Instead, focus on natural methods of stimulation, such as gentle abdominal massage in a clockwise direction.

5. Consult a Pediatrician: If your baby continues to have infrequent bowel movements or shows signs of distress, it’s essential to consult your pediatrician. They can assess your baby’s health and may recommend further interventions or dietary changes.

Regarding your concern about stimulating the rectum potentially causing the anal sphincter to loosen, it’s generally not a concern if done infrequently and gently. However, relying on this method regularly can lead to issues, so it's best to limit it and focus on other natural methods.

In conclusion, while breastfeeding is beneficial, it’s essential to monitor your baby’s bowel habits and address any concerns promptly. Constipation can be managed with dietary adjustments, gentle stimulation, and regular pediatric consultations. If you notice any alarming symptoms, such as blood in the stool, severe discomfort, or a significant change in behavior, seek medical attention immediately. Your pediatrician will provide the best guidance tailored to your baby’s specific needs.
