Start right. Bring your babies to your breasts as soon as possible after they are born. If the babies are in the NICU or for some other reason unable to nurse immediately, start pumping and saving your breast milk. If your babies are born at under 34 weeks, they will need fortified milk. A mineral-rich supplement can be mixed with your breast milk and given with a bottle for two or three feedings each day, depending on what your doctor recommends.
