Yet, within these quiet, often intimate moments, lies a profound biological dance involving a crucial hormone: prolactin . At Sleeping Baby Guide, we champion the Gentle Night Method , a philosophy rooted in responsive settling and attachment-safe practices, ensuring both you and your baby find peace and optimal development. This article delves into the science of prolactin, exploring why night feeding is not just about sustenance, but a vital component for establishing a robust milk supply, fostering deep bonding, and supporting your baby's natural sleep rhythms. Understanding Prolactin: The Milk-Making Hormone Prolactin, often dubbed the "milk-making hormone," plays a pivotal role in lactation. Produced by the pituitary gland, its primary function is to stimulate milk production in the mammary glands. During pregnancy, prolactin helps prepare the breasts for breastfeeding by developing mammary tissue. After birth, the removal of the placenta triggers a significant increase in prolactin levels, initiating copious milk production. The Science Behind Milk Production The process of milk production is a remarkable example of supply and demand. When your baby suckles at the breast, or when you pump, nerve endings in the nipple send signals to your brain. This stimulation prompts the pituitary gland to release prolactin. The more frequently and effectively milk is removed from the breast, the more prolactin is released, signaling the body to produce more milk. This intricate feedback loop ensures that your milk supply is perfectly tailored to your baby's needs. Alongside prolactin, oxytocin, often called the "love hormone," is responsible for the milk ejection reflex, or let-down, allowing milk to flow freely from the breast [^1].
