They reduce the inner tunnel diameter of your existing flanges, allowing mothers who require a smaller opening size to pump more comfortably and efficiently without purchasing a new pump.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I know which size flange insert to use?\u003c\/h4\u003e\n\u003cp\u003eA: Use the included measuring card and tape ruler to measure your nipple diameter (not the areola). The correct insert should allow your nipple to move freely in and out of the tunnel without rubbing on the sides. A well-fitted flange helps improve comfort and milk flow.
