FAQs

Can I use my HSA/FSA?

Yes, you can. Simply pay for your breast pump, milk bags and accessories using your FSA/HSA debit card at checkout, or pay with another credit card and submit your receipt to your plan administrator for reimbursement.

Do I need to use Milk Bags with Willow 3.0?

No! Willow 3.0 offers the option to pump into Spill-Proof Milk Bags or Reusable Containers. Milk Bags enable total 360 degree mobility, while Containers offer 180 degree mobility, superior to other wearable pumps. Learn More.

Will Willow 3.0 still work if I produce more than four ounces on each side?

Our Spill-Proof Milk Bags and Reusable Containers hold up to 4 oz of milk (8 oz total). Willow automatically shuts off when your Milk Bag or Container is full. If you pump more than 4 oz in a single session, you can easily switch out the bag or empty the container and continue pumping.

Meets my need!

The bags have really been helpful while back at work and at home! It’s much more efficient to immediately pop the bags into the refrigerator at work rather than pouring from one thing to another for storage. And there are less parts to clean! And at home, it’s much easier to care for my toddlers and baby since I can lean all the way over without spilling. While it’s significantly more expensive, it has been a great solution for me!

Thank you for sharing this feedback, Natalie! We appreciate you taking the time to review our Spill-Proof Milk Bags!
A great tip from some of our moms to store our spill-proof milk bags in the fridge, is to attach a removable plastic hook on the side wall of the fridge to hang our milk bags. This helps with easy rotation and keeps your bags upright, without taking up precious space! Please feel free to reach out to our Customer Care team if you ever need us - we are here for you!

Forever thankful!

I am an RN working in a critical care unit and I was really looking for the flexibility to pump while working and if things at work decide to take a turn for the worst being able to do what I need to do without wasting milk. I can vouche for them being spill proof while performing CPR. These pumps have forever changed my life. I am going on 9 months of pumping and nursing my daughter where as my first daughter I was unable to nurse long due to the inability to pump more flexibility.

Very Handy

They’re very handy! Saves about 5 minutes compared to the container. And at my job every minute saved counts! I just wish they weren’t as pricey.

Consistently Spill-Proof

I love these bags. I don't waste any precious milk and they freeze great and thaw great in a bottle warmer. Have not had any issues with them.
