Physiology of Human Lactation and Strategies to Support Milk Supply for Breastfeeding

Abstract

Despite advances across the globe in breastfeeding initiation rates, many families continue to report they are not meeting their breastfeeding goals. Concerns about milk supply, infant nutritional intake, and infant weight gain are among the most commonly cited reasons for early breastfeeding cessation. Nurses working with individuals during the perinatal period are uniquely positioned to educate families and offer evidence-based interventions to promote optimal milk supply, infant growth, and maternal mental and physical health. Such interventions include early and frequent skin-to-skin care, emptying of the breast, and professional lactation support. By implementing such evidence-based practices in the first hours after birth and connecting families to lactation support in the first 14 days, nurses can begin to help families achieve their breastfeeding goals.
