What this trial studies

This observational cohort study will follow 120 lactating mothers and their newborns over a maximum of two years to investigate the composition of human milk at various stages of lactation. The study aims to explore differences in milk composition based on maternal, perinatal, and infant characteristics, as well as the microbiota of the infant. Participants will provide residual human milk samples for analysis, contributing to a better understanding of breastfeeding and human milk's role in infant health.

Why it matters

Potential benefit: If successful, this study could enhance knowledge about human milk composition, potentially leading to improved breastfeeding practices and infant nutrition.

How similar studies have gone: While similar studies have been conducted, this specific approach focusing on longitudinal analysis of human milk composition is relatively novel.
