I loved these bags when I was filling them with milk and putting them into the freezer because of how flat they froze. I have started using that frozen milk for my almost 1 year old and I guess I got a bad batch, but I have lost 4 bags of milk in 1 day due to the seals on the side having a hole. I also can’t tell until it is thawing/thawed when milk is everywhere or gone. This is extremely frustrating because I had worked very hard pumping and breastfeeding and only had enough milk to get my baby to 1 year old. With the way these seals are broken, I feel like we will only actually have enough milk to make it to 11 months with my breastmilk and I will have to supplement with donor milk or formula. It’s very upsetting putting all that work in and relying on a stash just to have faulty bags. Please do better quality assurance so this doesn’t happen to any other mom.

I really like these Lansinoh breastmilk storage bags and use them regularly. The material feels thick and durable, with no strong odor, and I’ve never had issues with leaking. The double zipper seals well and keeps milk secure in the fridge or freezer. My only downside is that when the bags are very full, they can be a little hard to get to stand up on their own. Other than that, they’re reliable and convenient for storing breastmilk. The appearance is also great.

These storage bags have worked great for my nursing journey! They can hold quite a bit of milk although I wouldn’t recommend overfilling it because it definitely expands the longer they’re stored frozen. I prefer the thinner design of these bags as opposed to thicker because I feel like they store better long term. I found it easy to get all of the air out of the bag each time and the ziplock stayed sealed. One of the negatives I have is about the measurement guide being off but honestly just about every breast milk storage bag is that way. The measurements just never line up properly with what the bottle will say after a pumping session. It is almost always off by at least 2 oz. For example: what you would be 4 oz in the bottle will measure as 6 oz or more after being poured into the bag. These are also missing any type of pouring spout to get the milk out easier after warming.

These were my favorite breast pump bags. I never had issues with leaking and they were easy to open and pour into a pitcher or bottle. They kept my milk fresh as you can see; I stored them in a deep freezer. I tried other brands, but these were my favorite. I also appreciate how thin they were without being cheap. I could fit a ton in my deep freezer. I also liked how i could write the date above where it zips closed as it wasn’t awkward to write with a full bag since it was at the top.

I've tried a few different brands of breastmilk bags now, and unfortunately these are by far the worst I have used. I actually did not realize these bags leaked so much until a few months after using them. I started thawing a few and every single one leaked!! I never overfilled the bags or anything, and I always pushed out as much air as possible before freezing. The only upside to these bags are that they freeze very flat and are easy to stack into bricks, they also have a nice clear place to label. I just wish they actually worked.

Sterile pouches that hold up to 6 ounces, easily lay flat to freeze. Label for date and time as well as amount and name. It’s nice to know exactly how much you’ll be thawing before removing from freezer! Compact size, easy to take on the go with lay flat to freeze feature!

I’ve used many brands, but these are my favorite because the material is thick and durable. I never have to worry about leaks during the thawing process, which is so important when every drop counts. They are easy to seal and lay flat in the freezer, making them a great value for the price

Although these are super popular they did not work for me. These are my least favorite storage bags. They’re thin and flimsy. Very easy to spill milk out of and hard to get air bubbles out. Now they do lay flat and save room in the freezer, but I wouldn’t purchase again.

These bags work great for storing breastmilk! They are able to freeze flat and stack nicely. I do wish they had a separate pull tab with pour spout like other brands as I have had the bags collapse when pouring milk into a bottle resulting in spilled milk.

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.
