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.
