Buy now, pay later

Reggie Baby's flange inserts make pumping more comfortable and convenient. Find the perfect fit for optimal pumping efficiency and express more milk in less time. Enjoy a smoother breastfeeding journey with high-quality inserts that provide maximum comfort. The small sizes are flange inserts (17, 19, 21mm) which fit inside the standard breast shields to ensure a comfortable and effective fit for that size nipple. These sizes are usually for women with smaller nipples and will slip into the 24mm breast shield seamlessly. The larger sizes (24 & 27mm) are breast shields. They are their custom shields that attach directly to the collection cup and are designed to accommodate the larger nipple size. *All of our Reggie breast pumps comes with a 24mm breast shield standard. Please see the flange size guide to help you find the right flange size for you.

Breast Pump Flange Insert

How to fit a breast pump

When choosing a breastpump, it's important that you find the right fit. Most mothers who are pumping are not using the correct flange size. A flange that isn’t fitting correctly (generally too large) can allow too much of the areola/ tissue surrounding the nipple to be suctioned into the pump tunnel. Only the nipple is supposed to move back and forth, gently. This efficient suction causes milk to spray. A flange that is too large can damage this delicate tissue and cause pain, and it won’t suction effectively. To find the right fit, get your measuring tape out prior to pumping or breastfeeding. Measure across the base of your nipple only, the diameter, not any of your areola. Add 1 mm if you are breastfeeding (before breastfeeding or pumping), add 2mm if you are pregnant.
