Breast Milk Basics
The growth of breasts will cause many changes during pregnancy. In the second trimester, the milk lines are developed and a small amount of discharge might take place. A small amount of colostrums may come out in the third trimester depending on individuals. The number of blood vessels in your breasts seems to have increased and the areola area enlarges, with the color becoming darker.
Breast milk starts to form after delivering a baby. Mostly around 40 hours after childbirth, the amount of breast milk increases and you start to feel like breast milk is filling up in your breasts. People often refer to this as 'lactating.' The colostrums during the first few days after the delivery are not much. However, it is enough to feed your baby. First, it looks darker and yellowish, but after a few days, you will see pure white milk coming out.
Your baby's suckling action increases oxytocin and prolactin. These hormones contract the milk pipe to produce milk. When a baby's mouth touches the nipple, it signals the mother's brain to secrete a hormone called oxytocin. This contracts the milk pipe to not only produce milk, but also contract the uterus muscles.
If your baby bites the nipple correctly and suckles well, then, the amount of a mother's breast milk depends on how much your baby suckles it. The more your baby suckles your milk, the more milk your breast will produce, and vice versa.
