Willow Breast Pump FAQ

How does Willow work?

The Willow Wearable Breast Pump 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 – or into the reusable Milk Container that attaches to 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. Or, empty your Milk Container into a bottle or your favorite storage container.

What are the new features for Willow Generation 3?

The Willow was re-engineered how Willow pumps to yield more milk per session – and offer more comfort and control.

I love my Willow Pump! Not only did it help my milk production, but also made it super convenient to pump! We recently went to Hawaii on vacation and I was pumping everywhere! It made it super easy for me to pump while at the beach, at a restaurant or even on our scenic drives!

The Willow allows me to pump and do all the things (laundry/dishes/picking up) that need to be accomplished. I absolutely hated my old pump where even though it was portable I still felt like I couldn't do anything due to needing to carry the pump everywhere. I also hated feeling like I couldn't take care of the twins while pumping since the design basically negated me being able to pick them up and care for them- the Willow is completely the opposite and has been an absolute game changer for our family!

Literally the best pump EVER!! Worth the money and it’s very likely your insurance will cover some. This time around I am able to do laundry, vacuum, clean, push my toddler on the swing, carry my baby, etc. you need to make sure you have a good tight fitting bra on. If you want to hide the large breasted shape it gives you, you can put on a sweatshirt. It truly lets you be in whatever position you want, laying down, bending down, whatever you do- as long as you are using the bags. For this reason I choose not to use the reusable containers. Just getting part of your life back makes it worth the money!

I beyond love my willow pump. I was nervous about the amount of milk I would be able to pump but this is beyond my expectations. I have twins and one had to stay in the NICU was 10 days so the ability to pump on one side for him and feed on the other side for her was a god send!!!

I love how easy it is to place it and the pump does all the work while I can continue to do stuff. A few things that I have learned is to get the reusable containers! When wearing the pump don’t bend over because milk will spill out and leak on your shirt. At first I felt self conscious about how my shirt looked with the pump on and I didn’t like it but then I got use to it and people told me they could hardly tell I was wearing it. Overall a wonderful pump!!
