How to choose the right size of breastshields for you?

Answer: The inner diameter of the breastshield (B) should be 2-3 mm larger than the diameter of your nipple (N). 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. Maymom MyFitTM one-piece breastshields are available in 19 (S-), 21 (S), 24 (M), 25 (M+), 26 (L-), 27 (L), 29 (XL-) and 30 (XL)mm internal diameters plus 22 mm and 28 mm inserts to fit the majority of breast pumping mothers.
