Brief Summary
Researchers at Massachusetts General Hospital are interested in learning more about the neurobiology of well-being in new mothers and novel ways to support them during their transition to parenthood. This study aims to evaluate well-being in new mothers and their infant and the impact of a probiotic dietary supplement on the gut microbiome. This study hopes to help improve the existing knowledge of maternal postnatal health.

Outcome Measures
Primary Outcomes (1)
Coding Interactive Behavior (CIB) Negative Scale Score (range: 1-5; direction: Higher values indicate worse maternal responses) in the probiotic versus placebo group
Mother-infant bonding: Quantitative observational assessment of mother-infant bonding using the Child Interactive Behavior (CIB).
6 week
Secondary Outcomes (2)
Change in Toronto Alexithymia Scale (TAS-20) Total Score (range: 20-100; direction: lower scores indicate better socioemotional functioning) in the probiotic versus placebo group
Baseline to Week 6
Change in relative abundance of microbial taxa (operational taxonomic units) in fecal samples in the probiotic versus placebo group
Baseline to Week 6
Study Arms (2)
Subjects receiving Probiotic Dietary Supplement

1 chewable placebo tablet containing all the same ingredients except L. reuteri (DSM 17938 and ATCC PTA 6475) consumed once per day orally for 6 weeks beginning at Baseline (between 1 to 3 days postpartum) to 6 weeks postpartum.
