I am finding the discussion regarding the size of nipple shield interesting. I routinely use the regular size one without difficulty relating to size. I have not had good luck with the small ones. I do find that taping the shield to mother's breast using transpore tape or paper tape (1" size, about 3"-4" long) works well. It is important that the entire shield be taped --4 pieces of tape framing the flange of the shield. Pardee Hinson, MPH, IBCLC Charlotte, NC
