Autoclave instructions:

To autoclave, place the flange in 121oC, 1 kg/cm2 (or 14.2 psi) for 15 minutes. Test reports done by independent lab show that Maymom flange does not change physically after the autoclave procedure, and it can still pass the FDA 21 CFR, 177.1520 specifications for polypropylene (FDA PP report).


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. Maymom one-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.


How to measure the diameter your nipple?

Download the nipple caliper file, print it out, cut through the red line, fold along the green dots then you have made yourself a nipple diameter measuring tool!  See below for the finished ruler.
