Using the correct flange size with your Spectra breast pump is something you can’t compromise on. Using the wrong flange size can hinder milkflow and even lead to injury. Here’s how you can measure your nipple to help select the breastshield size that’s right for you.
How to measure your nipple
Begin by pumping as you normally would. If you’re brand new to pumping, we recommend pumping at a gentle setting and low speed to start. At the end of your pumping session, you’ll notice your nipple has swollen.
Then, it’s time to measure your nipple. You can measure with a standard ruler as long as it has millimeters on it, or you can use a nipple ruler specifically designed for measuring flange size, which many moms find easier to use.
Measure the diameter of the nipple at the base of the nipple. You’ll want to select a flange size that is 2-3mm larger than this measurement. Remember that it’s important to measure after you’ve pumped because you’ll want a flange size that leaves adequate room for your nipple to expand.
Tip: Try measuring in front of a mirror or using a camera phone to get a better angle for seeing the measurements.
Be sure to repeat the process several times to ensure you’re getting consistent measurements.
Signs of a good breastshield fit
A properly sized breastshield should be very comfortable. In fact, you should barely be able to feel it while pumping. Just a gentle tugging sensation on the nipple and nowhere else. You should not see any excess areola being drawn into the flange, and you should not feel a pulling sensation or pain while using your Spectra breast pump. After your pumping session, your nipple should be free of any redness or whiteness. Pumping should be pain-free, and if you’re experiencing discomfort while pumping it’s likely you’re not using the correct sized breastshield.
We understand that we don’t carry every flange size (click here to see a list of breastshields that are compatible with Spectra pumps) so if you measure and think you need another size, please contact Spectra customer support and we can help you find a stockist who does! 🙂
