WHY INFANTS, BABIES AND TODDLERS BENEFIT FROM PROBIOTICS

The gut is made up of trillions of live microorganisms responsible for 80% of our immune system, so having good gut health is extremely important for baby and toddler’s health for years to come. The gut also plays a huge role in digestion, skin health, brain chemistry, hormones, and immunity and is often referred to as a second brain.

A healthy gut makes for a healthy life!

And while you would think that baby comes into this world with a perfectly balanced little gut, that just isn’t the case. Baby’s gut bacteria (both the good and bad bacteria) is influenced from mom’s gut health in utero, gestational age, mode of delivery, diet and antibiotic exposure. And because of the modern world that we live in – high-stress, pro-antibiotic, nutrient-poor and abundance of refined foods, most moms’ gut health is depleted to some extent.

So while I am wary of adding any supplements or medicine into an infant’s daily life, I am a firm believer that probiotics are a must for most (if not all) babies to help them boost their growing gut health. They are generally safe for healthy babies, but as always, consult with your pediatrician before starting any probiotic, especially if your child has serious health issues. 

What are Probiotics?

Probiotics, or “good bacteria,” are microorganisms that live in your gut and have health benefits when consumed, like improved digestion. Probiotics are found in many fermented foods, like yogurt, kefir and sauerkraut, and eating these foods or taking a probiotic supplement may help boost the amount of beneficial bacteria in your gut. Prebiotics are the food that helps probiotics grow.

What do Probiotics Help with?

While probiotics may help infants with numerous different gut related issues, here are some of the main ones. Keep in mind that there is very little research on probiotics and infants but some clinical trials and anecdotal evidence has shown that they may be helpful for:

  • easing colic
  • reducing reflux
  • decreasing diarrhea
  • easing constipation
  • eliminating gas
  • skin issues – eczema, baby acne, dry or patchy skin
  • improving immunity
  • anti-inflammatory
  • reducing the risk of early childhood obesity
  • relieving a stuffy nose, respiratory infection, and trouble breathing
  • reducing the risk of food intolerances and food allergies
  • producing hormones, like serotonin
  • improving mood, motivation, and cognitive health
  • repairing damaged tissue from injuries (great for mobile babies and toddlers)

Even if your baby or toddler isn’t experiencing any of these symptoms, chances are they still could benefit from a probiotic.

6 best probiotic brands for infants, baby and toddler, lined up in a row on a kitchen counter.

Are Probiotics Safe for Infants and Toddlers?

Generally yes, all brands can safely be given to healthy babies or toddlers. Keep in mind that probiotics are considered a supplement and not a medication, so are not regulated by the FDA. When choosing a probiotic for baby and to ensure its safety, its best to look for one that has been certified by an independent body like ConsumerLab, USP or NSF International. Please consult your pediatrician before you start a probiotic or if you have any questions or concerns, especially if your child has a weak immune system, was born prematurely or has other health issues.

Types of Probiotics

Powder – you can sprinkle the powder onto a nipple or a pacifier or add it into a bottle of breastmilk or formula for baby. You can add it into a glass of milk, water, or juice or mix into yogurt or applesauce for toddler.

Liquid – you can place the liquid drops directly into baby’s or toddler’s tongue or add to a bottle of breastmilk or formula for baby or to a glass of milk, water, or juice for a toddler. You can also mix it into a serving of yogurt or applesauce for a toddler.

Formula – there are some infant formulas on the market that are fortified with probiotics

**Do not add probiotics to hot liquids or foods as this will kill off the bacteria in the probiotics.

Probiotics Your Infant + Toddler Need

B.Bifidum: one of the first strains to colonize in the baby’s intestines may help build immunity and eliminate eczema.

B. Infantis: helps with immunity and reduces inflammation as the bacteria crowds the gut and makes it inhospitable to foreign invaders (bad bacteria) to populate it.

L. Rheuteri: this strain is commonly found in probiotics as studies have shown that is helps treat colic and reflux.

How Often to Give Probiotics

If your baby or toddler has any symptoms from the list above, then I would give them the dosage on the package (or per your pediatrician’s recommendations) daily.

For preventive use, I would recommend giving them to baby or toddler several times a week, but it’s okay if you skip a couple of days a week.

Antibiotics – if your baby or toddler needs a round of antibiotics for any reason, it is essential to re-populate the good bacteria in their system as soon as the round of antibiotics is over. Antibiotics kill off all of the good and bad bacteria in the body. It’s super important to then load up on the good bacteria before the bad bacteria has a chance to reproduce. Probiotics can be given during the course of antibiotics, but make sure they are taken at different times of the day, and continue to take them for a few weeks after stopping antibiotics, or as directed by your pediatrician.
