Did You Know Flange Size Matters?
You wouldn’t buy any bra off the rack without checking the size on the label. But what fewer new moms realize is that the same principle applies to pumping. Your best flange fit might be different from the mom next to you.
As a reminder, the flange is the cone-shaped piece of equipment that sits directly over your breast. The important part to watch for sizing is the width of the opening. Watch your nipple during a pumping session to check your fit:
Too small: Some or all of your nipple rubs against the sides of the flange while pumping.
Too big: Your nipple moves freely, with space around it. A decent portion of your areola pulls in with your nipple, too, and rubs against the sides of the flange.
Just right: Your nipple moves freely in the flange, and you can see some space. Only a little areola is sucked into the flange tunnel with your nipple.
Flange size is measured in millimeters, and Ameda’s standard size is 25mm. We also offer custom flanges or inserts to accommodate six other sizes! Your flange fit might change as months go on, so recheck your fit periodically to keep pumping comfortable.
