Summary

This Mayo Clinic study looks at how a mother's stress, mood, sleep, and diet might affect levels of melatonin and an immune protein called sIgA in her breast milk. Researchers will follow 120 new mothers who are breastfeeding. The goal is to better understand these connections, not to test a treatment.

What could go wrong: This is an observational study, not a treatment trial. It cannot prove cause and effect, and results may not apply to all mothers or lead to immediate changes in care.
