The size of your flange insert is important for comfort and efficient pumping. Some moms will experience nipple swelling while pumping, so it's important to observe how your nipples look during a pumping session. While pumping, your nipple should not rub or feel squished inside the flange tunnel. Please choose the right size flange insert.
