Some women have nipples that turn inward instead of pointing outward or are flat and do not protrude. Nipples can sometimes flatten for a short time because of engorgement or swelling from breastfeeding. Inverted or flat nipples can sometimes make it harder to breastfeed. But remember, for breastfeeding to work, your baby must latch on to both the nipple and the breast, so even inverted nipples can work just fine. Flat and inverted nipples may protrude more over time as the baby sucks more.
Very large nipples can make it hard for the baby to get enough of the areola into their mouth to compress the milk ducts and get enough milk.
