Great way to keep organized!
I’m a milk donor and this is an easy way to keep track of dates and amounts when it comes time to donate! It’s obviously an extra step, which I don’t always have time for, but I think it’s worth it in the long run!

The best!
Love these bags! They are so thick, pour well, and have good space to write on. And the new technology is just amazing! As a pumping mom with over 4,000 oz in the freezer, this would have been amazing to have from the beginning of my journey.

Breast milk smart storage
I recently tried out the new storage bags with smart stash for the Willow app! This is helping to keep track of how much milk I have in the freezer! You can easily scan the bag when inside the Willow app and keep track of how many oz you have in storage. I am an over producer and enjoy tracking my journey. This is super helpful new innovative technology thank you Willow!

Really cool feature for logging
I never logged my milk bags previously bc honestly. . after labeling them and storing them, the last thing I want to do is go into an app and have to manually log all of that information back in these scan right into the app and if you have trouble scanning a bag in, there is a manual feature to log.

I have been pumping for
This review was collected as part of a promotion
I have been pumping for over a year now and have tried both small and large brand bags. Willow bags are my most-used bags, and this is why:
1. The opening is flexible. When I pinch the top to open it, it’s not flimsy, which makes pouring milk easy. The wide bottom makes it easy to stand, so I pour milk into 6 bags and close them all at once instead of one at a time.
2. The material is easy to label. It writes well with both pen and Sharpie.
3. Simple and to the point. After…

Storage bag
As a busy healthcare worker, these storage containers make my workflow much easier. I can simply scan and go without having to search for a marker to write the date and time. It helps save time and keeps things moving efficiently during a busy shift.

Know the exact amount you’re making
I love Willow bags in general but this takes it to the next level especially as a mom who wants to wean once she has enough frozen bags. This is a great to track to know what I have each day for my baby!

SO convenient!!
I LOVE these bags! The quality is such a soft feeling that I can’t help but love but most importantly, being able to stash my milk in the freezer and keep track of it all in the app! I can easily find out how much milk I have stored away without having to keep a mental or written note myself and is now as easy as clicking on the app. Sometimes I forget to write down the amount of ounces per bag and this allows for more of those forgetful mom brain days to be okay! As simple as pulling up the code and I have right on there how many oz are in there! 😍 HIGHLY recommend these!

Great product
I was so excited to try these out. I am glad I did. It is so much easier now to know how much breast milk I have in the deep freezer. Being able to track it also helps me keep track of my supply.

A lifesaving feature for NICU mamas
The smartstash feature is such a game changer for exclusive pumpers and especially mamas with babies in the NICU. My baby is no longer in the NICU but I know this would’ve simplified things significantly for me when it came to pumping for him during that time. I’d usually forget the total amount of milk I’d bring in and since it was kept with the nurses I had no way of accessing it to check how much I had provided. This would allow mamas to easily keep track of how much milk they’re bringing in for their babies. It’s such a smart and innovative idea. I absolutely loved it!
