Basically I have enormous breasts. I wear a 32HH bra and my nipples are extremely large. Does anyone know if there is a larger than 36mm size breast shield available? I am currently using the Medela manual pump with the 36mm shields and they are too small and causing me some pain. I am about to buy an electric pump but I can't find any breast shields large enough for my nipples. I would like to make sure the pump I buy has large enough shields. This is the most important thing. The only 40mm shield I have come across are glass and sold by Medela for their Symphony and Lactina breastpumps which I cannot afford... Help!
