How does Willow work?
Willow is unique because everything works inside the pump and inside your bra—with no external tubes, cords, or dangling bottles to hold you back.
First, you align Willow with your breast, wait for the pump to initiate latch, and then secure it inside your bra. Once latched, Willow senses let-down and automatically switches to expression mode based on your individual milk production. Your milk flows into the spill-proof Milk Bag tucked securely inside the pump. And the best part is you can move freely while you pump and track your milk progress in real time on the Willow app.
When you’re done pumping, simply open Willow and remove the Milk Bag (which doesn’t leak, thanks to our innovative one-way valve). Then pour it right into a bottle or store it in the fridge or freezer for later.
When can I buy Willow?
We are working hard to get Willow ready. Join our mailing list, and you’ll be one of the first to know when Willow arrives.
How can I be a beta tester or join a focus group?
Unfortunately, we no longer need women for our testing program. But we’d love to add you to our mailing list so we can let you know when Willow is available.
How does Willow fit on my breasts?
Willow is designed to fit women of all breast shapes and sizes. Unlike traditional breast pumps, Willow rests on top of your breasts and contains everything you need to pump—Flange, Milk Bag, and all—right inside its breast-shaped design.
Why is Willow shaped like a breast?
We designed Willow so it fits into your bra and looks like you (not a machine).
Will you offer a 27 mm Flange?
Willow comes with a 24 mm Flange, but we plan to offer a larger 27 mm size to accommodate more nipple sizes.
Do I need a special bra to wear Willow?
We recommend wearing Willow with a supportive nursing bra.
How much does Willow weigh?
A single Willow pump weighs less than one pound. In addition to making sure Willow won’t hold you back, we also made sure it won’t weigh you down.
Do I wear Willow all day or just when I pump?
Willow should only be worn while pumping. At the end of each session, remove the Milk Bag and pour it or store it in the fridge or freezer.
What does the Willow app do?
Since the Milk Bags are tucked inside Willow and out of sight when you pump, the Willow app is the only way to see your milk collection in real time. The app doesn’t control the pump, but it allows you to track your pumping sessions, view the suction level, order Milk Bags, get help when you need it, and more.
When will there be an Android app?
Willow will only be available for iOS at launch, but we plan to offer an Android app in the future.
Can I breastfeed on one side and pump on the other?
Yes. The all-in-one design of Willow makes it easy to pump while you breastfeed your baby because there are no external cords, tubes, or dangling bottles to get in the way.
Can I move around while I pump?
Absolutely! Willow gives you the freedom to move how you want to while you pump. Willow tucks into your bra so you can pump while you walk, multi-task, lean back, or relax. This makes everyday things like making breakfast or playing with your toddler totally doable. What you do while you pump is finally up to you.
Can I lie down while I pump?
Yes! You can lie back, relax, run errands, and do all kinds of everyday tasks while using Willow.
Can I adjust the suction?
You sure can. Willow has seven different suction levels so you can easily adjust the suction to your own milk flow and pumping needs.
How many ounces of milk does each Milk Bag hold?
Each Willow Milk Bag holds up to 4 oz. of milk.
What if I produce more than four ounces on each side?
Willow automatically shuts off when your Milk Bag is full. If you pump more than four ounces in a single session, simply switch out the bags and continue pumping.
Can I reuse the Milk Bags?
No. Our Milk Bags are designed to be used just once and then recycled.
How do I get my milk from the bag into a bottle?
Grab a clean pair of scissors, cut along the dotted line at the top of the Milk Bag, and pour into your bottle of choice. No messing with closures or seals anymore. And you don’t have to worry about the bag leaking or spilling because our innovative one-way valve only lets milk in—never out.
How long does it take to charge Willow?
Once you’ve plugged Willow in, it takes about two hours to fully charge. If you can’t charge Willow for the full two hours, a 20-minute charge will last for approximately one pumping session.
How many pumping sessions can I get before I have to recharge?
A fully charged Willow will work for approximately five pumping sessions (although it varies based on your milk production). A quick charge of 20 minutes is good for approximately one pumping session when you’re in a pinch.
