Human Milk Production: How Does Breastfeeding Work? : Did you know that your body gets ready for breastfeeding even before your baby is born? During pregnancy, your breasts go through changes that prepare them for making milk. These changes can make your breasts feel fuller and more tender. Once your baby is born and starts sucking, it triggers hormones in your body that tell your breasts to produce and release milk.
Milk production happens in the alveoli, which are like grape-like clusters of cells in the breast. After the milk is made, it gets squeezed out through the alveoli into the milk ducts, which are like highways that carry the milk through the breast.
Here’s an interesting fact: the size of your breasts doesn’t impact your ability to breastfeed. Whether your breasts are small or large, you can make the same amount and quality of milk.
