Best pump!

I love this pump, especially now with the reusable container. It has helped me get my supply back since I’m able to pump more often. Having to hooked up to an outlet would make me choose doing anything else on my to do list instead of “wasting” 20 min sitting. Worth the price!

Game changing

As I prepared for the arrival of my second child, I was dreading pumping. I remembered being endlessly tied down and forever at the sink cleaning pump parts. I decided I would breastfeed my second and NEVER pump. When it came time to go back to work, that would mean I would transition to formula. My first business trip was scheduled for only one month postpartum. As I approached the date, breastfeeding was going well and I was sad, but determined not to become a slave to a pump again. Enter the Willow. A few well placed ads had me researching a product that seemed too good to be true. A pump that fit MY needs. I ordered the pump and never looked back.

I'm now 3 months postpartum with a healthy, happy, breastfed baby. I have almost one month (!) of milk stored in my freezer. I pump when and where I need to pump - including on airplanes, in cars, and on the move. I can stay on schedule and not skip a beat when I'm away from my baby. There is no way I would be at this point without the Willow.

The details:

- Thrilled with the release of the new container and 21mm size. This allowed me to pump at home without unnecessarily using bags. The combination of the bags and the container truly makes this the most versatile pump possible! I'm hoping there will be additional sizes released for the regular flange for the bags in the near future. Having a flange that fits well is essential.

- Highly recommend watching all of the instructional and troubleshooting videos prior to…

More than convenient, it’s efficient!

I am a stay at home mom and just had my third baby in four years. While the Willow seems to be marketed toward moms working outside of the home, the pump has been essential to helping me take care of myself and my pumping needs while also caring for my family. I can pump and play with my toddlers, pump and fold laundry, or even pump and drive to preschool. I expected and am pleased with the freedom Willow gives me. What has been an unexpected, and beyond appreciative feature is the efficient latch/suction. I can pump more in much less time than with my Medela PSA. This let’s me squeak in pumping sessions even when I’m pressed for time. There was a bit of a learning curve, my pumps sometimes need to be reset, and can have difficulty with my abundant milk supply, but I have been thrilled overall with this pump!!

Fantastic pump!

I love the Willow pump for the freedom it gives me. I am able to move around, empty dishwasher, fold clothes, etc. while I pump. I really didn’t have much trouble at all Lear I gotta how to fit the Willow correctly and my production has gone up! When I go back to work in 2 weeks as a nurse I’ll be able to continue working while I pump!

Freedom

The ability to pump while doing chores, such as the endless loads of laundry a baby produces, or even just when out running errands in the little time outside the house and away from the baby, is worth every penny this pump cost. I love that I don’t have to worry about leaks, cause that milk is liquid gold!
