How is mother's milk produced

How is mother

The breast is a gland composed mainly of conjunctive and adipose matter, which provide support and protection of the mammary glands.

The milk originates in small groups of cells called alveolars and move towards the breast through the galactophorous ducts, which in turn act as reservoirs. These reservoirs are found at the back of the breast, behind the dark area around the nipple.

The production of milk begins with pregnancy. At this stage your breasts begin to undergo physiological changes, become more sensitive and swollen, and your nipples turn darker than usual.

Years ago, some experts thought this change in color helped the newborn see the mother's breast. However, there are no studies that prove this and other experts believe that, minutes after birth, babies can attach to their mother's breast even without opening their eyes.

During the third trimester of your pregnancy, those small granules known as Montgomery glands, around the darker area of your breast, begin to grow and become more visible, they secrete an oily and clean substance which lubricates and protects your nipple against infections while you breastfeed.

Changes also take place inside your breast. As the placenta develops, estrogen and progesterone are released, substances that stimulate the biological system and make possible the production of milk.

The greatest production of milk occurs between two and four days after giving birth. Women who already have had children may produce their milk sooner.

Once the placenta is ejected, a strong hormonal change takes place, the levels of progesterone and estrogen decrease quickly and there is an increase in the level of the hormone responsible for ordering your body to produce a lot of milk to feed your baby.


During the first days of breastfeeding you will produce a creamy substance, low in fat, yell in color, containing a large quantity of the protein known as calostro.

During the final days of pregnancy your breasts might secrete a bit of this first mail, and in some cases this happens in the second semester of your pregnancy.

How does is process work?

During the first days of breastfeeding you may feel some abdominal pain while baby feeds; that means that your body is secreting oxitocine, the hormone that helps the womb return to its pre-pregnancy size.

You may also feel relaxed and peaceful while breastfeeding, a little sleepy and tired. This means that baby is stimulating your production of milk.

Remember, the longer you breastfeed, the more milk you will produce.
