Breastfeeding success has nothing to do with the size of your breasts or nipples. Breast size is an inherited trait and determined by the number of fat cells you have. The breasts will enlarge with pregnancy and breastfeeding.
The small bumps on the areola are called Montgomery glands. They produce a natural oil that cleans, lubricates, and protects the nipple during pregnancy and breastfeeding. This oil contains an enzyme that kills bacteria and makes breast creams unnecessary. Use only water to clean your breasts. Soaps, lotions or alcohol might remove this protective oil. Each nipple has 15 to 20 openings for milk to flow.
Release of the oxytocin hormone while breastfeeding will also cause the uterus to contract. This may be more noticeable if you have previously had children. This mechanism helps your uterus return to its pre-pregnancy size quickly.
