How do I choose the correct breast shield or nipple insert size?

Watch this video to learn how to measure your nipple and choose the right breast shield/nipple insert size.

Use this helpful online tool to guide yourself through the sizing process step-by-step.

Watch this animated guide before pumping to make sure that your breast shields and inserts fit correctly.

The pump comes with 21 and 24 mm breast shields, and a 19 mm nipple insert.

If the inserts and breast shields that came with your pump don't fit, you can purchase a separate pack of 15 and 17 mm inserts for smaller nipples, and another with larger 28 mm breast shields and a 26 mm insert for mums who need bigger sizes.

Our full range of inserts and shields covers nipple sizes from 11 to 27 mm.

Check the following table to help choose the correct size of shields or inserts based on your nipple size.

Note: Using an insert is optional but recommended for achieving a proper, comfortable fit.

Find new parts online at www.philips.com/support or contact the Philips Consumer Care Center in your country.

Note: Shield and insert sizing and availability may vary between countries and regions.

If you're still struggling to find the right size, try using the cardboard sizing tool included in the box with your pump, or contact the Philips Consumer Care Centre in your country for assistance.
