As you think about newborn feeding, you can be assured that your body is doing what is needed to get ready to feed your baby. You do not need to do anything special to prepare your nipples. Simply wash them with water when you are in a bath or shower and dry them with a towel. You do not need to rub, roll or pinch your nipples to toughen them.
Although most women have nipples that stick out when the breast is stimulated, some women have nipples that stay flat or even "tuck in." This is called having inverted nipples.
If you want to test for this, you can gently pinch each nipple at its base. If the nipple does not stick out, see the section about inverted nipples and what you can do about it while you are pregnant.
Having inverted nipples only affects the first few weeks of nursing because breastfeeding makes even inverted nipples stick out during a feeding.
The hormones of pregnancy cause changes to your skin.
