Dear Lisa, In our state we are careful not to make a gadget from an appliance intended for another use. We could set ourselves up for malpractice suits. I use M_____a shields and they are inexpensive and are not latex so they don't have a strong smell. The only time I utilize shields is for the purpose of bringing out inverted nipples. The shield allows a more natural molding of the nipple for the babe's mouth. Within, 1 minute or so (after we see some NS) the suction is broken, shield removed and baby just pops right back on. After about 2 days shields are done away with altogether! Good Luck, Trina Ammar, RNC, IBCLC Monterey, CA
