Willow® Launches New Sizing Inserts To Reach More Moms


MOUNTAIN VIEW, Calif., June 2, 2021 -- Willow, the most mobile breast pump on the market, released a new line of sizing inserts to accompany its popular and innovative breast pump, theWillow Wearable Breast Pump Generation 3. The new inserts are available in sizes 15, 17 and 19 millimeters (mm) to offer more moms the freedom that comes along with using a Willow pump; which was designed with proprietary technology that responds to moms' body and maintains suction similar to a baby, enabling 100% leak-proof mobility.


The average flange size most new moms need ranges between 21- 27mm1, which Willow previously accommodated with its flange offerings. However, many moms - research suggests almost 25% - require a size under 21mm.2 With Willow's new inserts, women with smaller nipple sizes will have the opportunity to obtain the maximum benefit when using a Willow pump.


"We've listened to pumping moms who have been asking for Willow to accommodate smaller nipple sizes," said Willow Chief Marketing Officer, Sarah O'Leary. "Our expanded range of sizing inserts will allow more moms to pump with a sizing product specifically designed to work optimally with Willow's unique continuous latch technology. We're happy to report that 93% of moms who pump with Willow say they have less stress using our pump as they are no longer tethered to the wall and tied down with traditional pumps. We are thrilled to offer more moms the opportunity to meet their breastfeeding goals on her own terms."
