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 phase based on your individual milk production. Your milk flows into the disposable, 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.

What is the Willow Coaching Program?

We know that breastfeeding and pumping take some getting used to, and we don’t want you to go it alone. That’s why we provide 1:1 coaching to help you every step of the way. Your coach/pumping BFF will check in with you via phone after you’ve completed your first few pumping sessions, and you can always ask our team of experts anything via text. Our goal is to answer your questions and make sure you’re off and pumping with Willow.

Why is Willow shaped like a breast?

We designed Willow so it fits into your bra and looks like you (not a machine).

What Flange sizes do you offer?

Willow comes with a set of 24 mm Flanges, and 27 mm Flanges are available for purchase. Unsure of your size? Our Sizing Guide can help.

Do I need a special bra to wear Willow?

We recommend wearing Willow with a full-coverage nursing bra that’s stretchy and has a flap. Avoid underwire and padded bras.

What does the Willow App do?

As Willow works inside your bra, the Willow App displays what is happening. See things such as milk volume, pumping time and past pumping sessions. Compatible with iPhone 5 or newer.

When will there be an Android app?

The Willow App is only available for iOS (iPhone 5 or newer, iOS 10.2 or later). 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 so you can 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 lets you 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 adjust the suction?

You sure can. Willow has seven different suction levels in expression phase; 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 spill-proof, disposable 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, switch out the bags and continue pumping.

Can I reuse the Milk Bags?

Willow Milk Bags cannot be reused. Our disposable, spill-proof Milk Bags feature a one-way valve so milk goes in and doesn’t come out. Store them in the fridge or freezer, and cut them open when you’re ready to pour them into a bottle.

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 the amount of time you pump for each session). A quick charge of 20 minutes is good for approximately one pumping session when you’re in a pinch.

Is the Willow Pump covered by insurance?

Some women have told us they’ve been able to obtain full or partial reimbursement for their Willow Pump through insurance. We recommend you contact your insurance provider to see if they will cover some or all of the cost of the pump.

What are the ACA guidelines for insurance coverage for breast pumps?

ACA states your health insurance plan must cover the cost of a breast pump. It may be either a rental unit or a new one you’ll keep. Your health insurance plan may have guidelines on whether the covered pump is manual or electric, the length of the rental, and when you’ll receive it (before or after birth). But it’s up to you and your doctor to decide what’s right for you.

How can I get reimbursed through my FSA or HSA?

Most HSA and FSA accounts can receive a reimbursement for Willow. You would follow the normal process as any other medical reimbursement claim. You will need to reach out to your FSA or HSA provider for more details.
