Probiotics for Infants: Addressing Constipation and Formula Concerns - Pediatrics

Lactic acid bacteria


Hello, doctor.
My child is 2 months old and has a bowel movement every two days.
I would like to help him have daily bowel movements.
Is it okay to supplement with probiotics? He is currently drinking a mixture of Nestlé hydrolyzed protein formula and Meiji formula.
Will long-term consumption of these two formulas together affect his gastrointestinal health? Or is it recommended to stick to one type of formula? I’ve heard that children who drink hydrolyzed protein formula may experience a longer period of milk aversion.
Is this true?

Having a bowel movement every two days is considered normal, as long as the stool is not hard.
There is no need to supplement with lactobacillus for this reason (especially since newborns already have a sufficient amount of beneficial bacteria in their intestines, and additional probiotics are generally not necessary before six months of age).
Different brands of formula have varying compositions, and mixing them is not recommended, particularly with low-allergen Nestlé hydrolyzed protein formula (mixing would negate its purpose of reducing the risk of allergies in infants).
The claim that children on hydrolyzed protein formula experience a longer period of milk aversion is unfounded (clinical experience in outpatient settings does not support this).

When it comes to addressing constipation in infants, probiotics can be a helpful option. Probiotics are live microorganisms that can provide health benefits when consumed in adequate amounts. They can help balance the gut microbiota, which is essential for healthy digestion and regular bowel movements. For a 2-month-old infant, it is generally safe to introduce probiotics, but it is crucial to consult with a pediatrician before starting any supplementation. The pediatrician can recommend specific strains of probiotics that are suitable for infants, such as Lactobacillus rhamnosus or Bifidobacterium lactis, which have been shown to be effective in alleviating constipation.

Regarding the use of two different formulas, such as Nestlé hydrolyzed protein formula and Meiji, it is generally advisable to stick to one formula for a consistent period. Switching between formulas can sometimes lead to gastrointestinal upset, as different formulas have varying compositions of proteins, fats, and carbohydrates. This can potentially confuse the infant's digestive system, leading to issues like gas, bloating, or even constipation. If you are considering using both formulas, it is best to do so under the guidance of a pediatrician who can monitor your child's response and make recommendations based on their specific needs.

As for the concern about hydrolyzed protein formulas leading to a longer period of milk refusal (or "nursing strike"), there is some anecdotal evidence suggesting that infants who are on hydrolyzed formulas may experience different taste profiles compared to standard formulas. Hydrolyzed formulas are designed to be easier to digest and are often used for infants with allergies or sensitivities. However, the taste may not be as appealing to some infants, which could lead to a preference for other types of milk or food. Again, this is something that should be discussed with your pediatrician, who can provide personalized advice based on your child's feeding habits and nutritional needs.

In summary, introducing probiotics can be beneficial for your infant's constipation, but it is essential to consult with a healthcare professional first. When it comes to formula feeding, consistency is key, and it is generally recommended to use one formula at a time unless advised otherwise by a pediatrician. Lastly, if you have concerns about your child's feeding preferences or any potential issues related to the formulas being used, don't hesitate to reach out to your pediatrician for guidance. They can help ensure that your child is receiving the appropriate nutrition and support for their development.
