It is well known that using the correct breastshield size is important for your pumping comfort and optimal milk supply. One size will not fit all.

Compared to Medela valve, our design of valve allows your precious milk to flow easier into the bottle. The pump in style replacement tubing set will fit Medela Pump in Style Original (sold before 2004) and Pump in Style Advanced Breastpump sold after July 2006. Maymom breastshields can be connected with Medela storage bottles and other standard-sized bottles like Gerber, Playtex and Ameda. They are 100% compatible with Medela valve and Medela membrane.
