Principle of breast milk secretion

The mother began to secrete milk in the second trimester, and began to release milk under the effect of oxytocin and prolactin after delivery. As can be seen from the picture, the baby is sucking, stimulating the nerve sensor on the nipple. These sensors send information to the hypophysis of the mother’s head to secrete prolactin and oxytocin into the mother’s blood, and promote the mammary gland and its tissues to secrete and release milk, which does not include the effect of what the mother eats or drinks to the production of milk. Only two things are included: the baby sucks the stimulation, and the mother receives the signal to secrete milk.

When the baby sucks the breast for the first time, it immediately stimulates the milk-ejection reflex to make the breast milk flow out. This is a neurotic stimulus. The stimuli that cause the milk-ejection reflex include: the baby sucks, and the mother hears the baby crying. Mothers should maintain a happy mood. If the mother is in a bad mood because of fatigue, pain, anxiety, it will inhibit the milk-ejection reflexion. The production of breast milk and the amount of lactation are also affected by the complete emptying of the breast and the number of sucking, which means that the more babies suck, the more breast milk mother secrete.
