Brief Summary
This study aims to determine the effect of three factors (delivery type, feeding type and the use of two different dietary supplements) on rebiosis after disbiotic delivery. This is a randomized, single-blinded study with two parallel arms. Group 1 will receive L. reuteri (10\^8 CFU) once a day, group 2 will receive B. longum and P. Pentosaceus (10\^9 CFU) once a day.
