Breast Shield Sizing Guide

Use the coin method to measure your pre-pump nipple size.

Take a pre-pump measurement of your nipple, at the base. Hand stimulate to make sure your nipple is fully erect before measuring. For optimal use of our FluidFit Breast Shields, it's important to not deviate from nipple size more than 1mm. If your nipple measurement is smaller than 20-22 mm, it's best to use smaller silicone alternatives.
