Robin, They sound very much like my memory of dimpled nipples. I thought dimpled nipples need not be flat, they simply have a portion that flips in and out, leaving a moist, macerated site with lactation. The Lactation Institute sells a product called a Dimple Ring that holds the "shy" part of the nipple out by compressing around the nipple base / areola to allow time to air dry before it "hides" again. Makes me think of that cute comic "inverted nipples? no just shy" or something like that. Carla
