The aim of this study is to evaluate the effects of a probiotic formulation on the daily crying patterns of infants. It is hypothesized that participants given the probiotic formulation will show a significant reduction in daily crying duration compared to participants receiving the placebo.


Participants diagnosed with symptoms of infantile colic will be recruited to participate in this randomized, double-blind, placebo-controlled, two-arm parallel study. Eligible participants will be enrolled in this study for 6 weeks, and will undergo a 1-week run-in baseline period followed by a 4-week interventional period, then a 1-week follow-up period.

The study will consist of 7 visits (V0 to V6): 4 in-person visits that alternate with 3 phone calls.
