I have purchased and used probably more than 600 of these bags. I have only had maybe 4 bags leak while defrosting in a bowl of warm water (note, I often filled with 6.5 or 7 ounces even though they state to only fill up to 6 ounces and I often jammed them wherever there was space in the freezer). I have heard of a lot more "casualties" with other brands. This is also the brand they supplied me with while we were in the NICU. Best price is always at Walmart - always a couple whole dollars cheaper than elsewhere.

I usually don’t even leave reviews but I wanted to warn other moms to that I definitely wouldn’t purchase this brand ever again %26 I would advise anyone not to purchase either, They were fine to store my breast milk in but when I went to defrost them they had a hole in the side/seams and my milk leaks out. Also not my first breastfed child so I know I didn’t over fill the bag or do anything else wrong. I was so upset as you know it takes so much time and effort to pump %26 soon as I go to feed my baby BOOM no milk in the bag left. Ugh I have used the entire pack, now I have to figure out how to safely defrost all this milk I have. Not worth it! Spend a few extra bucks for the medela brand

To all the ppl complaining about leaking bags, i have to ask if they made sure to lay the milk bag flat when freezing to allow room for the milk to expand? And also if they made sure to not fill past 6 oz? I have only ever had one problem with my milk leaking when thawing but noticed it was due to rough handling of the frozen milk bag. Otherwise I have never had a problem. Just try to keep a designated container to store the milk upright once frozen and handle the milj with care would be my advise. Other than that I find these bags durable for the most part just dislike that when the milk is not frozen, it tends to be super flimsy since the plastic is more on the thinner side, but that is a minor complaint.

Lansinoh breastmilk storage bags are my absolute favorite. They are easy to fill and transfer milk, write pumping details, and lay completely flat for freezing. Such an essential item for any breastfeeding mom! I received this breastfeeding accessories from the Stellar Product Testing Panel

I received this breastfeeding accessories from the Stellar Product Testing Panel, but I purchase these regularly! I have been using Lansinoh breastmilk storage bags since my son was born 3 months ago and prior to that, I used the same bags with my daughter (now 3). They're the only brand I trust to store my previous breastmilk (especially after seeing that my sister-in-law lost about 2 months worth of her stash due to a store-brand bag being faulty). These bags are incredibly durable, don't leak if they drop on the floor (closed of course) and they can stand up on their own which makes them fantastic for re-heating or filling. They are the easiest to open, lay nice and flat in the freezer and pack easily for road trips. I highly recommend these to any new mom!

I absolutely love these storage bags. The plastic is flexible and not super stiff. They are easy to open and close, and even to get the air out of the bag. The plastic does not stick together like other milk bags. The curved top allow the milk to easily be poured into a bottle without having to worry about spilling. The milk bags freeze flat and don't take up as much room in the freezer like other milk bags. The top of the bag is easy to write on to display the date and ounces. Thanks to the Stellar Product Testing Panel for providing me with this breastfeeding accessories.

The breast milk bags are great. You can put them in the fridge or freezer and don't have to worry about them getting freezer burnt. They are sturdy and easy to label as well as pour out. They are easy to label and take along and I like the design and feel it is an excellent choice for storage bags. I got these items for free from #Lansinoh for being a brand influencer, in return for product reviews and promotion by sharing with friends, family and through my social medias. The opinions above may be based upon my sponsorship, but they are 100% my own unbiased experiences and opinions!

Daughter used with all her kids.

Easy to close, freezes flatter than other brands

I love these! I used them with my first born. Sturdy and I don’t have problems with leaking!
