You can choose one or two of these probiotics, alternate between them, or cycle through different ones during different phases.
As covered in detail in chapter 20 of It Starts with the Bump, certain probiotics can help your newborn build a healthy microbiome. This can have a range of downstream benefits, including preventing allergies, infections, colic, and reflux, and just generally helping your baby feel better and sleep better.
These drops include a combination of several strains including L. reuteri, B. Infantis and L. rhamnosus GG. This would be my top choice for a general probiotic for infants, although if your newborn has a sensitive stomach, it may be easier to start with a single-strain probiotic such as Evivo or BioGaia.
Best for: general health
This provides L.Reuteri DSM 17938, which is especially useful for colic and reflux and preventing G.I. infections in preemies. It is used in many hospitals and has been studied in newborn babies for decades. This particular version also includes vitamin D, avoiding the need to give separate vitamin D. drops.
Best for: colic and reflux
This infant probiotic provides a specific strain of B. infantis that has been extensively studied in babies. It is a powder, so it is not quite as convenient as drops, but it is backed by positive data showing that it persists in the GI system, so can help to establish a healthier microbiome longer term. The studies on B. infantis indicate it may help prevent allergies, improve sleep, and reduce crying time.
Best for: preventing allergy and building a healthy microbiome
