Quick Answer
Use the Breast Pump Sizing Kit to measure your nipple diameter and match it to the correct flange insert for a comfortable, efficient pump fit.
Why Accurate Flange Sizing Matters
A correct flange fit is essential for comfortable pumping and optimal milk output. If the flange is too small, it can cause friction and pain; if too large, it may not create a proper seal, reducing suction efficiency. The Breast Pump Sizing Kit includes a range of inserts to help you find your perfect fit.
When to Re-Check Your Size
Your nipple size can change over time due to factors like breastfeeding frequency, hormonal changes, or weight fluctuations. It's a good idea to re-measure every few months or if you notice discomfort or a change in output. The kit makes it easy to adjust your flange size as needed.
Step-by-Step Guide to Using the Breast Pump Sizing Kit
- Prepare for Measurement: Ensure your nipple is at its natural, unstimulated state. Avoid measuring right after pumping or nursing, as your nipple may be temporarily larger. Clean and dry your hands and the kit components. Measure at a consistent time for the most accurate baseline.
- Measure Your Nipple Diameter: Use the sizing card or ruler included in the kit to measure the diameter of your nipple in millimeters. Place the card against your nipple and note the measurement where the nipple meets the areola. Write down the measurement so you can refer to it when selecting the insert.
- Select the Correct Insert: Match your measurement to the corresponding insert size in the kit. If you are between sizes, choose the larger size to avoid pinching. Insert the chosen flange insert into your pump flange. Double-check that the insert sits securely and creates a smooth surface.
- Test the Fit with Your Pump: Attach the flange to your Willow pump and start a pumping session. Observe that your nipple moves freely in the tunnel without rubbing the sides, and that you feel no pain or discomfort. If you feel any pinching or see excessive areola pull, re-measure and try a different size.
- Adjust as Needed: If the fit isn't perfect, try another insert from the kit. It may take a session or two to find the ideal size. Once you find the right fit, note the size for future reference. Keep the kit handy for re-measuring when your size changes.
