Are different Breast Shield sizes available?
Every pump comes with a 24 mm Breast Shield attached to each Cup.
Depending on which version you have, you may also have 21 mm Breast Shields included in the box.
Packs of two 21 mm or 28 mm Breast Shields are also available to purchase.
Our Breast Shields are sized based on the width of the base of your nipple.
You can measure the width of the base of your nipple with a ruler. The Breast Shield sizes are as follows:
Base of nipple width between approximately 16 mm and 18 mm = 21 mm Breast Shield
Base of nipple width between approximately 18 mm and 21 mm = 24 mm Breast Shield
Base of nipple width between approximately 21 mm and 25 mm = 28 mm Breast Shield
The size of your nipples may change over the course of your breastfeeding journey, so please check them regularly.
We have an easy to follow guide on how to find the right Breast Shield size that lots of pump owners find helpful..
