If your breasts have been enlarged surgically with silicone or saline implants, your nipples may be more or less sensitive than normal. Once you've delivered a baby and your milk has come in, you may have exaggerated breast engorgement. You may also experience mastitis, with pain, fever, and chills that are more intense than usual.
Although most approaches are compatible with breastfeeding, it depends on the kind of surgery you had. Incisions made under the fold of the breast or through the armpit shouldn't cause any trouble. A "smile" incision around the areola increases your risk of having breastfeeding problems.
You won't know exactly how your milk supply has been affected by breast augmentation surgery until you try to nurse. If you still have feeling in the nipple, you have a much better chance of having a full milk supply.
If you're able to produce only a portion of the breast milk your baby needs, you'll need to supplement with formula or donor milk.
Let your baby's doctor know about your surgery. He or she will need to keep a close eye on your baby's weight gain to make sure that the baby is getting enough to eat.
If you had surgery because you had underdeveloped breasts, you may have trouble producing enough milk. Use a pump after each nursing session to stimulate production.
If you are thinking about getting breast implants and want to be able to nurse your babies, postpone surgery until after you have had your last child. This is a good idea anyway because your breasts can change so much when you are pregnant and nursing.
