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.
Your breasts go through four stages when making milk: 1  Stage 1: This stage begins in your second trimester (months 4 to 6) of pregnancy. 2  Stage 2: This stage begins about 3 to 5 days after you give birth, when your mature milk comes in.  Stage 3: This stage starts when your baby is about nine days old.
