Our breast pump sizing inserts are designed to help optimize comfort and output for moms who measure smaller than 21mm.
Available in sizes 13mm, 15mm, 17mm, 19mm and 21mm for use with 24mm Willow flanges and containers.
Did you know: you should replace pump parts every three months for optimal performance. Normal wear and tear can impact suction and output! Having extras on hand is helpful in the event that you lose a part, too.
Work great
I’m loving my inserts! They have helped with output, emptying more completely, and comfort during pumping!
I love these! Not only do they change your flange size they help you not have to buy so many flanges. I also love how comfortable they are for pumping
Inserts work great!
I LOVE my Willow pump. It’s hard to be tethered when you can be free. It empties my breasts and is just so easy. Maintenance is key, and listening to your body is key with this system. These inserts are heavenly and definitely made a HUGE difference in my pumping experience when I realized I needed to resize. These shipped fast and were packaged with the utmost care. Thank you!
Sizing inserts can only be used with a 24mm flange or 24mm container insert.
