Baby probiotics raise many questions: Are they safe? Effective against colic or reflux ? Which strain should you choose? Here's everything you need to know for your newborn or young child. child.
Key takeaways:
- Baby probiotics help relieve colic, GERD and constipation in babies.
- Each probiotic strain has a different effect on the infant's digestive system.
- They are generally well tolerated by children, under medical supervision.
- A course of treatment can begin in the first few months, depending on the baby's needs.
- Recent studies show clear benefits for immunity and the microbiota.
What are the effects of probiotics in babies?
Baby probiotics can help relieve colic , improve bowel movements , support digestion , strengthen the immune system , and limit certain disorders such as eczema .
Improvement of intestinal transit
Probiotics can help reduce constipation in babies by acting on their gut flora . Certain strains, such as Bifidobacterium lactis, are associated with a reduction in constipation or episodes of diarrhea.
Colic relief
In infants suffering from colic , studies have shown that Lactobacillus reuteri DSM 17938 can reduce the duration of crying. The gut microbiota plays a role in these early digestive disorders.
This improvement could be linked to L. reuteri's ability to modulate intestinal inflammation and strengthen the mucosal barrier of the digestive tract. According to several studies, this strain also helps reduce excessive colonic motility , often implicated in prolonged crying associated with colic.
It is one of the few to have been tested specifically in infants in a double-blind study, with results deemed statistically significant from the first week of administration.

Reduction of GERD and bloating
Some probiotics for GERD work on the infant's digestive system by promoting an optimal acid-base balance. This could help reduce GERD symptoms , such as regurgitation or digestive discomfort.
Immune system support
Babies' immune systems are still developing. Strains like Lactobacillus rhamnosus GG can support the gut flora , which plays a key role in the immune response [source: Nutrients , 2023 – Systematic Review].
Reduced risk of atopic eczema
Some newborns with an allergic predisposition may benefit from the addition of strains such as Bifidobacterium breve .
These bacteria can help modulate intestinal inflammation , thus limiting the signs associated with atopic eczema [source: Clinical and Experimental Allergy , 2022].
Rebalancing the gut microbiota after antibiotics
After a course of antibiotics , the gut flora can become unbalanced. The intake of appropriate probiotics can support its gradual restoration, in conjunction with a suitable infant diet .

As you've seen, each strain plays a different role depending on your baby's needs. Now let's move on to an essential question: how do you choose the right probiotics and administer them correctly on a daily basis?
Which probiotics should I choose for a baby?
To choose the right probiotic for your baby , you need to consider the strain , the dosage , the age- related needs, and the desired effect (digestion, bowel movements, comfort, prevention). Some strains have been the subject of specific studies.
The most studied strains in infants
- Lactobacillus reuteri DSM 17938 is often used for digestive comfort. It has been associated with a reduction in crying in infants suffering from colic.
- Bifidobacterium lactis is known to support transit and help restore the balance of the microbiota.
- Lactobacillus rhamnosus GG (LGG) supports immunity and can be used from the first months.
Table: Strain / Effect / Recommended Age
| Strain | Main effect | Recommended age |
|---|---|---|
| L. reuteri DSM 17938 | Reduces colic, improves digestion | From birth |
| B. lactis BB-12 | Regulates bowel movements, reduces diarrhea | From 1 month |
| L. rhamnosus GG | Supports intestinal immunity | 3 months and over |
| B. breve M-16V | Provides support in cases of eczema | 3 months and over |
How to read labels and avoid pitfalls
Check the full name of the strain , the number of billions of live bacteria per dose , and the absence of unnecessary additives. A good product will specify the dosage per dose, the target age , and storage instructions.
Form and dosage: what you need to know
For newborns , probiotics in drops or powder form to be diluted are the most suitable. The form should be easy to administer and contain a stable daily dose , often around 1 to 5 billion CFU.
Is there a “better probiotic”?
There is no single universal probiotic. The “best” one depends on the desired effect , the child’s digestive profile , and the context (breastfeeding, cesarean delivery, taking antibiotics, etc.).
Have you found the right strain for your baby 's needs? Now let's see how to administer it effectively on a daily basis , without stress or forgetting.
How do you administer probiotics to a baby?
Baby probiotics come in drops, powder, or sticks. They are given in milk , by spoonful, or on the bottle nipple. It's important to respect the daily dose , choose the appropriate form , and monitor the child's digestive needs .
What is the best way to give them away?
You can give baby probiotics directly by spoonful, mixed into a little breast milk or formula. Avoid liquids that are too hot, as they can impair the effectiveness of the live bacteria.
At what time of day should they be administered?
It is often taken in the morning , before or during a meal. This allows for better digestive tolerance and more efficient absorption of the beneficial strains in the intestine . The key is to maintain a regular schedule.
How many days does a probiotic treatment last?
A course of treatment can last from 7 to 30 days, depending on individual needs. Some products are formulated for short courses of treatment following a course of antibiotics , while others are designed for prolonged daily use . Always read the manufacturer's instructions.
What is the correct dosage?
Most probiotics contain between 1 and 5 billion CFU per dose. This dose is sufficient to support a child's gut flora without overloading their system . There is no need to give more.
Which form to choose: drops, powder or stick?
Drops are convenient for toddlers. Powder can be mixed with milk or water, and sticks are more suitable for older children . The choice depends on age, habit, and the product being used.
Can they be mixed with food?
Yes, as long as the food is at room temperature . You can add them to applesauce, a warm bottle, or even directly onto the pacifier. Avoid mixing them in very hot drinks to preserve their benefits.
What should I do if I miss a dose?
Don't panic. If you miss a dose, don't double the dose the next day. Simply continue the treatment as prescribed. The effectiveness of probiotics is built on regularity, not on a single dose.
Are there any risks or side effects to giving a probiotic to a baby?
Probiotics for babies are generally well tolerated. In some cases, temporary discomfort such as gas may occur. Their use is not recommended for immunocompromised infants .
It is best to seek the advice of a healthcare professional if you have any doubts.
Most baby probiotics are well tolerated. They contain natural strains, already present in the infant 's microbiota , such as certain bifidobacteria or lactobacilli .
In the first few days, some babies may experience gas , bloating, or looser stools. This type of reaction is related to the adaptation of the gut flora and usually disappears without intervention.
In children with a genetic disorder , a serious bacterial infection , or an immunodeficiency , adverse effects may occur. The route of administration must be strictly controlled.
Probiotics and breastfed baby vs bottle-fed baby: what are the differences?
An infant's diet influences the composition of their gut microbiota . Breast milk naturally contains prebiotics and beneficial bacteria. Infant formulas can be enriched to mimic these, but probiotic requirements may differ.
Breast milk naturally contains probiotics.
Breast milk contains lactobacilli , bifidobacteria , and oligosaccharides that promote a beneficial gut flora. It is a natural source of support for the baby's digestive and immune systems.
Infant formulas are sometimes enriched with probiotics.
Some infant formulas are enriched with strains such as Bifidobacterium lactis or Lactobacillus rhamnosus . This aims to mimic the benefits of breast milk, but the digestive function remains different.
A microbiota that was initially different
Studies show that breastfed babies have a gut microbiota richer in bifidobacteria . This may play a role in preventing infections and digestive disorders.

What this changes in the choice of probiotic
Some products are formulated according to feeding method . If you are breastfeeding, choose a strain adapted to the mother's gut flora . If you are bottle-feeding, choose a probiotic that contains the right strains to support digestion.
Zoom: The impact of delivery method and antibiotics on the microbiota
The way a baby is born, and their exposure to antibiotics , directly influences their gut flora . These factors can affect bacterial diversity and sometimes increase the risk of diarrhea or digestive imbalances.
Vaginal birth: a more diverse microbiota
During a vaginal delivery, the baby comes into direct contact with the mother's vaginal and fecal bacteria. This helps to naturally enrich its gut microbiota from the first hours of life.
Birth by cesarean section: different composition of the microbiota
Babies born by cesarean section have a different gut microbiota, lower in bifidobacteria and higher in skin species . This can delay intestinal balance and affect immune development.
Antibiotics alter the gut flora from the very first days
When a baby receives antibiotics in the first few weeks, their gut can lose some beneficial bacteria. This imbalance is associated with an increased risk of diarrhea or mild digestive upset.
Why is this important in the long term?
The gut microbiota plays a role in digestive health, but also in the overall development of a child's immune system . Its balance from birth can influence digestive function and even food tolerance.
FAQ: Do you still have questions about baby probiotics?
At what age can probiotics be given to a baby?
Probiotics can be given from birth , provided the strain is suitable for newborns and approved for this use. Always check the recommended age on the product label.
Can probiotics be given to a breastfed baby?
Yes, a breastfed baby can absolutely receive probiotics. Breast milk already contains beneficial bacteria and natural prebiotics, but a probiotic supplement can enhance its action, particularly in cases of colic, reflux, or after a course of antibiotics.
Should probiotics be taken as a preventative measure or only when a problem arises?
Some babies may benefit from probiotics as a preventative measure , particularly after a cesarean section, antibiotic treatment , or in cases of sensitive digestion. Others use them occasionally, as needed .
What is the difference between probiotics, prebiotics and synbiotics for babies?
-
Probiotics : live microorganisms.
-
Prebiotics : fibers that feed these bacteria.
-
Symbiotics : combining the two to strengthen intestinal function .
All three can play a role in the balance of the microbiota .
Do baby probiotics need to be kept in the fridge?
Not always. Some products need to be refrigerated , while others are stable at room temperature . This depends on the form (drop, powder, stick) and the manufacturer . Always follow the storage instructions.
Can natural probiotics (yogurt, kefir) be given to a baby?
Yogurt and kefir contain live bacteria , but they are not always suitable for infants. They may contain whole milk or cultures that haven't been tested on babies. It's best to wait until after 12 months, unless advised by a doctor.
Can probiotics be given to a baby with a cold?
Yes, unless medically contraindicated. Some probiotics are associated with immune system support. They can complement a healthy lifestyle during a mild cold, but they do not replace the advice of a pediatrician.
Can you give your baby several courses of probiotics in a year?
Yes, several Treatments can be considered, especially if your baby is going through different periods: dietary changes, gastroenteritis, antibiotics… The interval between treatments will depend on the product and the context.
