Review of Willow Pump Bags 

One of the things that is great about the Willow is they have the option to pump into spill proof milk bags. When you use these spill proof milk bags for pumping, you can do almost anything while pumping. 

Some of the things you can do while pumping with the Willow are: 

The Willow pump bags are what make the Willow so versatile. A lot of moms who are nurses and want to pump at work to provide milk for their baby while they are away.

I know many moms who have jobs as nurses end up choosing the Willow as their pump because of the flexibility it gives them to pump while working with the spill proof bags. 

If you have a job where you need to be up and around and moving, you definitely need to use this pump and the Willow pump bags. 

If you are chasing after a toddler like I am, it is so much easier to pump into these spill proof milk bags and not have to worry about leaking milk.

They give you the flexibility to pump in so many situations.

Can You Reuse Willow Pump Bags

No, you cannot reuse the Willow pump bags. The one exception is if you are pumping into the same bag during the same feeding, which I have some more details on below. 

The reason you cannot reuse the Willow pump bags is because the bags are sterile on the inside and you should not mix warm and cold milk. 

Mixing warm and cold milk raises the temperature of the cold milk. It creates an environment where bacteria can grow more easily.

When a bags is used for a single pumping session, you do not have the problem with mixing different temperatures of milk. I have more info on mixing warm and cold milk in this article here.

I have more details on the one exception where you may want to pump into the same bag during one pumping session. 

You can find out more about using one bag during the same feeding in this article here: How Much Does The Willow Pump Hold?

Even though it isn’t sanitary to reuse the Willow pump bags, you luckily also have the option of reusable containers with the Willow for the 2nd and 3rd generation of the Willow pump. 

Can You Freeze Willow Pump Bags?

Yes, you can freeze milk in the Willow pump bags. The milk is best for up to 6 months according to the CDC. Make sure you add a date on the bag before putting it in the freezer. 

Even though you can free milk in the Willow pump bags, remember that you do not freeze milk in the containers. Transfer milk to a storage bag first and then freeze it. 

If you are using the containers and want to freeze milk in bags for later, I tested a few types of milk bags and these are my favorite (link to Amazon).

Pro Tip: Keep your milk bags organized and put all the frozen milk bags from the same month in a larger gallon – sized ziplock bag. Add the “milk pumped date” and “expiration date” to the outside of the ziplock bag.
