Flange Size


The flanges seem like they are holding me back since low milk flow with the average size. Would moving up to the larger flange help?



Flange fit is very important for successful pumping. When your nipple is drawn into the tunnel of the flange, there should be open airspace around your entire nipple. As your nipple is pulled in and out it should not touch or rub along the sides. If you notice it is touching that would indicate that you need a larger flange.

All the best,
