Do Babies Need Probiotics?

Baby being born via Caesarean Section coming out

A baby’s framework for a strong gut and digestive system begins at birth:

  • A vaginal birth transfers the mother’s gut bacteria to the infant, which initiates the baby’s microbiome.
  • Caesarean section birth may make it harder for the baby to develop a healthy balance of good and bad bacteria in their early years because there is no initial exposure to mommy’s vaginal flora.
  • Breastfeeding can help a baby develop a healthy microbiome because it acts as food for the bacteria growth and diversity. Breast milk is high in probiotics.
  • Well-developed infant formula can also contain probiotics
  • Skin to skin contact between mom and baby, eye contact, breastfeeding, sharing the same bed; all of these things help with the microbiome.

Not all babies need probiotic supplementation, but many will benefit from them. Here are a few reasons why they might need them.

  • Cesarean births may make it harder for the baby to develop a healthy balance of good and bad bacteria in their early years because there is no initial exposure to mommy’s vaginal flora in the birth canal.
  • Formula-fed infants do not get the benefits of probiotics directly from breast milk, so using a formula that has added probiotics or the use of probiotics can play an important role in forming the formula fed baby’s gut biome.
  • Mom has stomach issues prior to birth/during pregnancy
  • A baby’s mother had antibiotics during delivery
  • Whenever a baby is given antibiotics
  • Acid Reflux
  • To help prevent thrush
  • Newborn Gut Deficiency which can cause:
  • Colic-like symptoms
  • Trouble with bowel movements (constipation or diarrhea)
  • Frequent Upper Respiratory Infections
  • Diaper Rash
  • Poor Sleep

Probiotics can not only help with the gut microbiota during the first years of life, but they can be beneficial for your baby’s overall health. Your baby’s gut microbiome can help build your baby’s immune system, prevent autoimmune diseases and other health conditions, and just help with your baby’s overall health.

Do Breastfed Babies Need Probiotics?

Breast milk does contain powerful probiotics, however, some babies will benefit from additional probiotics. As I listed above, there are various reasons any baby might need probiotic supplementation, including colicky babies, use of antibiotics, recurrent thrush, etc.

What to Look for in Probiotics for Breastfed Babies


There are a lot of different strains that are used in probiotics for infants. Many of them claim to help with colic, diaper rash, and other digestive problems.

In my experience with probiotics, you sometimes have to experiment with different strains to find the best one for you, though this is often more for adults.

90% of babies have Newborn Gut Deficiency and lack the essential good bacteria B. infantis.

For the purposes of this post, I specifically focused on infant probiotics that contain B. infantis because of how well it works with breast milk. This strain has been shown to help create a protective environemnt in a baby’s gut. When paired with breast milk, it thrives in a baby’s gut and populates very quickly to get rid of the harmful bacteria that are linked to eczema, allergies, and colic.

This study found that “Probiotic supplementation with B. infantis within the first month postnatal, in combination with breast milk, resulted in stable colonization that persisted until at least 1 year postnatal.”

Another probiotic that can be beneficial is B. bifidum.


It’s important to make sure that the brand you buy is dedicated to creating high-quality products:

  • Free from additives
  • Sugar-free
  • Free of common allergens
  • Quality checks

Safety of Probiotics for Babies

safety first sign
safety first traffic sign on bluesky

According to Breastfeeding USA:

“One caution to take into consideration when considering probiotic supplementation for infants is the fact that newborns have immature immune systems. As with any nutritional supplement, it is important to remember that quality control can be an issue. There have been instances where probiotic supplements were contaminated by potentially harmful fungi and bacteria. Due to the immature immune system and the immature digestive tract, routine use of probiotic supplements in infants younger than 3 months should only be done under the supervision of your child’s health care provider.”

The best way to determine whether or not a specific probiotic is good for you and your baby is by reading through the list of ingredients and checking if there are any additives, preservatives, coloring, yeast, or sugars. No matter what, your probiotic should be dairy free.

Also watch out for claims of being “100% natural” because this does not always mean the product is safe. It’s safest to go with products that are USDA certified organic and non-GMO verified.

Here are some safety precautions to keep in mind when using probiotics:

  • Speak with your doctor before starting
  • Do not use after expiration date
  • Follow the instructions carefully on the container for administration and storage
  • Monitor your infant for any adverse reactions
  • Keep an eye out for any recalls

Are liquid or powder probiotics better for babies?

You can use either one.

The main benefit of using a powder probiotic is that you can easily mix it into bottles or food that your baby eats, like yogurt or applesauce. This is helpful for babies that don’t like the taste of straight up probiotics because they can get used to it by mixing it with their food. Powders also tend to be cheaper than liquid probiotics, but they can get expensive if your baby takes a lot of them daily.

Liquid probiotics can be easier to administer since you can use a dropped for it. Many parents just find this more convenient!

How to give a baby probiotics

You will want to read the instructions on the probiotic you buy. However, in general, it’s usually recommend to mix it with a small amount of breast milk, formula, or even solid food.

When I was first told to give probiotics, I was recommended to put it on my finger for my baby to suck off. Some recommend putting it on your nipple.

It can be a good idea to start with a smaller dosage of probiotics to make sure your baby reacts okay to it and build it up over the course of a few weeks.

How long does it take for probiotics to work with babies?

This depends on the type of probiotic you are using and how much your baby takes. Generally it will take around two weeks to see results, though some may see benefits sooner or later. Some brands, such as Evivo, claim parents see results in as little as just a few days.

What problems can probiotics cause for infants?

Babies can have issues with gas and bloating from probiotics, so it’s important to start with a small dose to see how your baby responds. For some babies this may mean taking them for a week or two before building up the dosage. If you find that these symptoms continue, you should consider finding a different type of probiotic for your baby.

Sources of Probiotics for Babies

Breast milk is obvoiusly one of hte best sources of probiotics for a baby, especially when they are not eating solid foods.

Once they are able to eat solids some good sources of probiotics to consider are yogurt, kefir, fresh fermented foods like sauerkraut and kimchi.

There are so many options out there for baby probiotics, it can get confusing. If your chosen probiotic doesn’t seem to be working for your baby, you can always switch to another kind. It is awesome when we find such a simple way to help our babies with digestion and support their immune systems!
