If your breast pump flange can’t fit to you, it can result in some problems. One obvious problem is that you cannot pump enough breast milk. Another potential problem is that it may make your nipple hurt. This is the worst thing to moms. Well, how to check if your breast pump flanges fits? There are many ways for you to check.

Make sure your nipple freely move in the channel of the breast pump and little or no tissue is inside the tunnel of the breast pump. If you find there is milk still in some areas of your breast, this flange doesn’t fit you. If you feel pain in the nipple, you should change another flange.
