Why Proper Flange Fit Matters
Using a flange that's too large or too small can cause pain, reduced milk flow, and even nipple damage. This affordable insert is the easiest way to dial in your fit without buying an entirely new pump kit. Learn more about proper breast pump use at the CDC's Breastfeeding & Pumping Resource.
