Most pumps come with a 24-26 mm flange size, most women are between 11-16mm, that the difference between a £1 coin and a 5p coin.

Using a flange that is to big, can cause issues such as:

• breast trauma 

• low milk yield

• low confidence and anxiety

• lowering milk supply

• increase need for formula

Using the correct flange size can 

• increase milk supply

• pain free, comfortable pumping

• increased confidence

• less need for formula

Using an hospital grade pump, we can experiment with (almost) every mm sized flange from 9mm-30mm in four different shapes to find the one that fits you, gives you the most yield with no pain.
