A Simple Nipple Test
Nipples come in all shapes and sizes, and most babies can handle these variations. Sometimes, if the mother's nipples lack elasticity or invert when compressed, a baby may have difficulty getting a good latch. This difficulty may temporarily worsen during engorgement, when the breasts get fuller and the breast tissue is even tighter and less elastic. Over time, these problems resolve, but mothers with inverted nipples may need extra help to get breastfeeding off to a good start. After birth, if baby still has difficulty attaching to your breast, contact a breastfeeding specialist, La Leche League leader, or Nursing Mothers Counsel.

While others may be flat.
