1 One of these hormones (prolactin) acts on the milk-making tissue, building up the milk supply. 2  The other hormone (oxytocin) causes the breast to push out or release the milk already there. 3  This release of milk is known as the let-down reflex (sometimes called the milk ejection reflex). The more often your babyâs sucking causes a let-down and the more milk that is removed from your breasts, the more milk will be made. 2  Respond to your babyâs feeding cues. 3  Crying is a late sign of hunger. 4  Breastfeed your baby often.
The breast is the tissue overlying the chest (pectoral) muscles. Women's breasts are made of specialized tissue that produces milk (glandular tissue) as well as fatty tissue. The amount of fat determines the size of the breast. The milk-producing part of the breast is organized into 15 to 20 sections, called lobes. Within each lobe are smaller structures, called lobules, where milk is produced. The milk travels through a network of tiny tubes called ducts.
