Most of the lactation text books have a paragraph on the Prolactin Receptor Theory suggesting that after delivery of the placenta prolactin levels increase as progesterone levels decrease. The prolactin is then captured by the prolactin receptor triggering a jak-stat5 translation process within a lactotroph creating a component of breastmilk. Unfortunately, explanations of the Prolactin Receptor Theory rarely address the up-regulation of prolactin receptors, the impact of oxytocin on prolactin release, nor the impact of skin-to-skin care and frequent breastfeeding during the first several postpartum day on prolactin release and up-regulation of prolactin receptors. This presentation will expand the Prolactin Receptor Theory and discuss postpartum care and practices to promote earlier lactogenesis II and increased milk volume.

Learning Objectives:

Objective 1: Describe the role of prolactin and prolactin receptors in lactogenesis
Objective 2: Discuss the impact of frequent and prolonged skin-to-skin contact and frequent breastfeeding on lactogenesis II
Objective 3: Develop a plan to modify the postpartum environment to promote breastfeeding duration and exclusivity
