Medela Breast Pump Parts - Breastshield size 24mm M x 1 single item
The breastshield is the part of the pump that fits directly over your nipple and forms a seal around the areola. It's very important that you have a correctly fitting breast shield, in terms of both comfort and how much milk you can express. The breastshield should tightly close around your nipple, while still leaving enough room for it to move back and forth.
Many women are not aware that breast pump shields come in different sizes, and that there is a lot of variation of nipple sizes - regardless of breast cup size. Having the wrong size shield can cause discomfort, and limit the amount of milk you can express.
All Medela breast pumps are originally sold with a 24mm (M) standard size breastshield in the boxed set, which suits most women. Though sometimes it isn't right - but it's something you'll only know after you have started using your pump. If you are finding that your nipple rubs along the edge of the tunnel as the pump is operating, then you should try a larger size. (Refer to the Sizing Tab for more information).
