Final answer:
Successful lactation relies on an adequate milk supply, which is established through on-demand breastfeeding and is regulated by hormonal responses to the baby's sucking.
Step-by-step explanation:
Successful lactation depends on adequate milk supply rather than factors such as frequent use of pacifiers, supplementing with formula, or scheduled feeding times. The process of lactation is tightly regulated by hormonal signals and the demand of the infant. When a baby suckles at the breast, this stimulates the release of prolactin, which furthers milk production, and oxytocin, which is responsible for milk ejection. Establishing a robust milk supply typically involves on-demand breastfeeding, which allows the supply to adjust based on the infant's needs. During the initial days postpartum, colostrum provides vital immunoglobulins to boost the newborn's immune system. Over time, the composition of breast milk changes from colostrum to transitional milk, and finally to mature milk that optimally meets the infant's nutritional needs with a balance of foremilk and hindmilk.
