Frequently asked questions

What is the best way to freeze breastmilk bags?

The best way to freeze breastmilk bags is to lay them completely flat. Freeze It Flat is designed to do exactly that, giving you even, stackable pouches that maximize freezer space and make your milk stash easy to organize.

How do you store breastmilk in the freezer to save space?

To store breastmilk in the freezer without wasting space, use Freeze It Flat to freeze each bag flat. Once frozen, the bags can be neatly stacked or stored upright in bins, helping you create a tidy system that saves room and makes finding bags faster.

Why is Freeze It Flat the best breastmilk freezer storage solution?

Freeze It Flat keeps breastmilk bags organized, uniform, and protected. By freezing your milk flat instead of in clumps, it prevents wasted freezer space, makes thawing easier, and helps you keep track of your supply more efficiently.

Can freezing breastmilk flat help with faster thawing?

Yes! Breastmilk that’s frozen flat thaws more quickly and evenly than bulky, misshapen bags. Freeze It Flat helps you create thin, flat pouches that defrost faster—making feeding time less stressful.

I wish I had this when I started pumping!

"I have used this a handful of times, and WOW. I have the single one, but should have just gone for the double!! This thing really works and makes it so your milk freezes tight and flat so it is so much easier to make into bricks! You won’t regret it"

— Amanda T. (5/5)

"Thank goodness for this product! I’m fitting so many more frozen bulk bags in my freezer now. Everything looks nice and organized! Truly love this and recommend it to my mom friends!"

Perfect for type A parents!

"I’ve been using the Freeze It Flat by Milkworx and I honestly wish I knew about it sooner! As a breastfeeding mom, freezer organization is everything to me, and this has completely changed my milk storage. It freezes my bags perfectly flat so they stack neatly and save so much space. My freezer looks so much more organized and aesthetic, which I love because I’m very type A. It also makes rotating and storing my stash so much easier. Definitely a must-have for any pumping or breastfeeding mom!"

Freeze It Flat in WI

"I am past having babies and nursing, however I buy this for every one of my friends and friends’ kids who are having babies. I would have loved the ability to store my breastmilk flat and stackable. Instead, I had to use beer cases to put my frozen breastmilk in."

— Kristi K. (5/5)

Saving so much freezer space now!

"Super easy to use! My favourite thing about this is that I can freeze my breastmilk bags anywhere in the freezer even if it’s not on an entirely flat surface because this contraption keeps it flat no matter what! Highly recommend!"

Saves SO much space!

"I make a lot of milk bricks and this allows me to fit 2 more bags in each brick! Saves SO much freezer space. I will say it’s a bit more time consuming but it’s worth it if you are limited to space! As an over supplier I’m very grateful for the space I have saved using these!"

— Allison V. (5/5)

The best product!!

"This has TRANSFORMED my freezer storage and organization. Our freezer looks so much better and I am able to fit so much more neatly. Not only is this a space saver, it’s a much more practical way of storing milk. I am in love. This is now the gift I’ll be gifting all my mama friends. Highly recommend!!!! Who knew something like this could bring us so much joy, especially as an over-supplier. I love this product!!!!!"

— Kat (5/5)

Works Amazing For Freezing Motif Bags Flat!

"I was a little hesitant about whether this would work with my Motif bags, but it works amazing! I use the single Freeze It Flat and freeze in 5oz increments. I honestly wasn’t sure it would get my bags flatter than my other method of freezing, but it definitely did. This has been such a game changer for storing milk neatly for optimal storage space!"
