Sorry - I hit the wrong button and my mail was sent before I could even ask the question! Anyway, I thought I had read somewhere that breast shells (the devices used prenatally to "correct" inverted nipples) have never been shown to make a difference for minimizing the problems associated with inverted nipples. Does anyone know where I can find this information--perhaps a study? Thanks to all, Therese Weickert, RNC, CLE Grand Junction, CO
