BEST STORAGE BAGS
Obsessed with the fact that these attach to most pumps! Pumping right into the bag and not having to clean parts 24/7? The best! Perfect for flat freezing too!

Very convenient and reliable
Very convenient and reliable, they are very easy to fill, seal tightly without leaking and save a lot of space in the freezer. I also like the material feels durable and safe for storing milk. 100% secure

LEAKS
I used these bags to store breast milk while exclusively pumping for five months. As an oversupplier, I had a significant amount of milk to freeze, and initially, I had no issues filling or storing the bags. However, now that I’ve begun using the frozen milk, I’ve discovered that many of the bags have developed holes and are leaking. This is incredibly disappointing and unacceptable, especially considering the time, effort, and care that goes into pumping and storing breast milk. The loss of this milk is devastating—it represents countless hours of work and cannot simply be replaced or measured in monetary terms. I truly believe this is a serious quality issue that warrants attention from Lansinoh, as it has resulted in a substantial and meaningful loss.

Thick material
I love these lansinoh milk storage bags. The plastic is really thick and when you freeze it it doesn’t leave wrinkles in the bad. It’s easy to pour milk in it and easy to pour the milk out of it when it’s defrosted.

Sturdy and reliable!
These bags are so awesome. I had over 4000 oz. Saved up in the freezer. I saved so much and never got holes in them. The ounces were super accurate too!

My go to!
These bags are the only ones I’ve liked using since day 1 of breastfeeding my twins. The best! The shape makes it super easy to freeze flat and bag up.

Scared they will leak
These are very hard to close so I'm scared they could leak my milk that I worked very hard for. They're also super thin and I prefer a more sturdy bag. But they work for what you need them for.

The best milk storage bags!
The BEST breastmilk storage bags! I used them with my first, and will definitely use them again with any future children! You can get a good amount of milk in them without the bags ripping and stores easily.

Used to be great, now dont bother.
These used to be great and the only bags I used. Now they’re much thinner, and more often than not leak out the top of the zipper on the side seam. I’ve wasted so many bags because like 1 out of every 3 or 4 doesn’t leak. I will be switching brands once I’m through the ones I have.

My go-to storage bags
I love these breastmilk storage bags! I exclusively pumped two babies and stored all of my milk in these. They stack really well so I could easily store them and keep them organized in freezer bags. I’ve never had any issues with milk leaking either which made the whole experience stress-free

Pump Directly with Spectra!
These are so great. I used them with my first and never had leaks. Years later, using them again and they even work with my Spectra pump! Can pump directly into these bags for an easy clean up.

Compared to other bags, this is my favorite! Holds a lot more and it can fit into some breast pumps like spectra

The bag works fine to store your milk however I loose some milk when pouring in from my wearable because of the oval flaps. No matter how I position it they always get in the way and makes a mess, some losses have been more than others. I wish it had a better design. These are definitely better for storing milk directly in them when pumping from a wall pump.

Leaks
I’ve lost at least 8 oz due to them leaking, it’s super frustrating cause I try to make sure that the seals are locked but once I put them in the fridge they leak everywhere.

Easy storage
Many fit in my freezer. It comes with a label for times, and dates. Stands my bottle warmer so it's easy to dethaw. Fits right on my pump. I can store so many with little space taken up in my freezer .

Great Bag Overall
The bags were great! They had no leaking & kept the milk fresh. They were easy to use when defrosting I like how it stayed sealed ! It was easy to transfer to the bottle as well. I can say I wish the bag was a bit more thick.

Super convenient and easy to use as a mom, however I have had a few leak or split which is frustrating when thawing. They freeze easily when laid down and easier than others to get the bubbles out.
