Standard sized 25 mm inner diameter is most comfortable for the majority of breast feeding moms. However, other sizes are available too. Many other sizes to choose from (refer to dropdown selection for range of sizes) For compatible valves, refer to product images. How to choose the right size of breastshields for you? The inner diameter of the breastshield (B) should be 1-2 mm larger than the diameter of your nipple (N) AFTER a pumping session or 3-5 mm BEFORE a pumping session. You should be able to see free movement of your nipple during pumping and there should be little or no suction of the areola into the tunnel of the breastshield. When it comes to pumping comfort, every millimeter counts. That is why we design a series of breastshields of small increment sizes. Maymomone-piece breastshields are available in many different sizes (refer to dropdown selection for range of available sizes) to fit the majority of breast pumping mothers.
