This document summarizes evidence-based interventions to support breastfeeding. It describes interventions during pregnancy, such as peer counseling and breastfeeding education, which increase breastfeeding self-efficacy and initiation rates. The document also outlines postpartum supports like the Baby-Friendly Hospital Initiative's 10 steps, support from healthcare providers, and peer support groups, which have been shown to increase breastfeeding continuation and exclusivity. While progress has been made in developing breastfeeding support systems, additional research is still needed to determine the most effective supports.
