Measure the nipple diameter AFTER a breast pumping session.

Choose a breast shield with an internal diameter that is 1-2mm larger than your nipple diameter. If you measure BEFORE a pumping session, you can only estimate to get one that is close. Try one that is 3-5mm larger than your nipple diameter.

Example:
if your nipple diameter AFTER a pumping session is 18mm, a 19mm breast shield is the best.

If your nipple diameter is 18mm BEFORE a pumping session, you can cry 21mm breast shield.
