Research
has shown that one-third or more of new mothers pump more comfortably
and effectively with a larger flange! If you feel discomfort when
pumping, even on low suction, or pump less milk than you believe you
should, you may need a larger flange size.
Ameda's Custom Breast Flanges replace the standard flanges (25mm)
included with most Ameda pumps and kits. Each box includes two flanges
and two inserts.
Medium/Large includes flanges that are 28.5mm and 30.5mm (standard size is 25mm).
(The Medium/Large flanges are already included in the Ameda Purely Yours Ultra pump).
