The goal of this pilot randomized controlled trial (RCT) is to examine donor human milk (DHM) as a clinical intervention targeted at achieving beneficial microbiome signatures in full-term infants who are exposed to intrapartum antibiotic prophylaxis (IAP) therapy during labour. Secondarily, this study aims to compare the infant health outcomes of sleep and growth between groups to assess if these outcomes are mediated by infant feeding type or potential differences in microbial signatures. Finally, this study will compare maternal outcomes of depression, anger, breastfeeding self-efficacy and breastfeeding rates between groups. The hypothesis of this study is: that replacing formula with DHM supplementation will minimize gut microbiome dysbiosis and foster homeostasis following supplementation. In addition, it is hypothesized that improved homeostasis will promote improved sleep and growth outcomes in participant infants. Finally, mothers whose infants receive DHM will have lower depression and anger scores and high breastfeeding self-efficacy and exclusive breastfeeding rates compared to mothers whose infants receive formula.
