How does the PersonalFit Flex™ Breast Shield yield more milk vs the traditional, 90 degree shields?

The new 105° opening angle and oval shape of the PersonalFit Flex breast shields allows more flexibility for mom to position the shield in different ways while she pumps, based on what’s comfortable for her. When let-down occurs, mom’s milk ducts get bigger – the new shape and angle allows the milk to flow more freely. Changing the opening angle of the flange from 90 degrees to 105 degrees made a difference; it better matched the contour of the breast and reduced compression of the milk ducts, which allows milk to flow more freely through them. This change resulted in increased volume of milk expressed during a pump session -  11.8 percent more overall on average. The 11.8 percent is the average but every mom’s personal experience will differ.

How should I clean my PersonalFit Flex™ Breast Shields?

The PersonalFit Flex Breast Shields should be washed and sanitized prior to first use. They should continue to be washed after each use and sanitized once daily. Cleaning instructions for the PersonalFit Flex Breast Shields are the same as the cleaning instructions for your other breast pump parts that come in contact with your breast or breast milk; please refer to the breast pump instructions for use for detailed cleaning instructions.
