Simply grasp your nipple between you thumb and index finger. Press your thumb and finger together several times around the base of your nipple. If it is inverted, the nipple will go in instead of out. If the nipple is flat, it will stay the same. If you find that one or both of your nipples are flat or inverted, talk to your public health nutritionist or nurse.
Most women can produce enough milk to meet the needs of their infants.
The secret is to nurse often to build up your milk supply. The more you nurse, the more milk you will make. You can learn to nurse discreetly. Before you try nursing in public, watch how other moms do it. Practice at home in front of a mirror.
