👉 Nipples secrete a clear, milky fluid known as milk letdown or lactation fluid, which plays a crucial role in breastfeeding. This fluid is produced by the mammary glands and is rich in nutrients, proteins, and hormones like prolactin and oxytocin. The letdown reflex is triggered when the baby suckles, stimulating the nipples to release this fluid, which helps moisten and nourish the infant's mouth, facilitating easier feeding. The composition of milk letdown fluid can vary slightly based on the mother's diet and overall health, but its primary function remains to support the newborn's growth and development by ensuring an adequate supply of milk.
