The probiotic Bifidobacterium Infantis can be life-changing for parents who are sleep-deprived or stressed out due to a fussy uncomfortable baby. This naturally occurring bacteria is becoming increasingly uncommon in the US due to things like antibiotic and pesticide overuse, but has been found to be vital for the digestive systems of babies. It has been widely reported to help calm chronically fussy babies, and help children who are having trouble sleeping through the night. Many parents have found that a child experiencing sleep regression can be soon put back on a healthy schedule by introducing B. Infantis into their diet. The probiotic als does wonder for gassy babies, as it helps regulate digestion. It is also recommended for babies suffering from thrush/rash issues.
