A CustomFit breast flange can make all the difference when you begin expressing breastmilk. For breastfeeding mothers with larger nipples, an ill-fitting breast flange can cause pain and nipple soreness. Replacing your standard breast flanges with larger sized CustomFit flanges can eliminate discomfort that you experience while pumping. For those mothers who require a smaller sized flange, the Flexishield Areola Stimulator helps to stimulate let-down while providing a reduced flange size. When used, the Flexishield mimics the feel of a baby’s mouth while breastfeeding.
