Lansinoh 20435 Breastmilk Storage Bags, 25-Count Boxes (Pack of 3)
Expressing breast milk from work takes a lot of time and dedication, so anything that will make the process easier is appreciated by moms. Storing milk in bottles takes up valuable freezer space and means that you have to keep purchasing more and more bottles to build up your stash of food for baby. These plastic breast milk storage bags come pre-sterilized, and are easy to carry around–as theyre not much bigger than a travel pack of tissues. In fact, they come in a tissue-style dispenser, making them easy to access and store. Each bag stores up to 6 ounces, or 180 milliliters of milk, and seals tightly to preserve freshness. Bags lay flat in the freezer saving plenty of space for more milk or other foods. Milk transfers easily from bag to bottle with no spillage. A tab above the fill area lets you write the express date, volume of milk, and the name of your child (in case you are handing it off to a busy daycare provider for feedings) on the bag without worry that you … >>> Special Offers and Product Promotions

Haven’t had a problem with leaks so far. Make sure you don’t drop them after they are frozen.
I did notice an odor with the first few bags of milk in my stash, but that may have been because they were kept in the fridge for a few days before freezing. Baby has not had any objections to the rest of the milk thus far. If you do notice an odor, it may be a problem with your breast milk having an excess of a certain enzyme (or something … check out the breastfeeding sites for more info.) Just to be on the safe side on avoiding possible odors, I have been storing them in batches of 10 or 12 bags in a bigger ziploc freezer bag.
Freeze them by laying them flat (make sure you seal the bags well.) That will make them super easy to thaw.
The best indicator I have that these bags are great is that my husband likes them and has no complaints about them
These are my favorite bags. I originally had the Medela bags because I thought they would be easier (you can pump directly into those). I found that I didn’t like pumping into the bags because I couldn’t get a good measure at the end. I have tried the easy pour bags also, and they were not really that ‘easy’.
I like these because they have two seals. And I have found them cheaper than the Medelas.
I have found these bags to be the best ones out there. They are thicker mm of plastic, have a double seal and a separate area to write on to avoid ink contamination. In my opinion, they are also much easier to pour to/from than other brands.
I also appreciate how they lay flat for more space-efficient storage. They have held up very well in my deep freeze in arctic temperatures!
I have used approximately 2,000 bags (seriously) and I have had only 9 that leaked. While I was sorry to lose those bags, I consider 9/2,000 to be pretty impressive odds.
These are more expensive than other ones out there, but I will pay that price to store my “liquid gold”!
If you are continually having difficulty with leaking bags, make sure you are freezing no more than 6 ounces at a time. Even though it looks like it will hold more, the milk will expand in the freezer. Also, you may want to freeze smaller quantities of milk so that there is less waste. You want to ensure that your baby will drink all that you defrosted, rather than having to discard it. I found it helpful to freeze some amounts in larger quantities, like 4 or 6 ounces and then smaller “top off” amounts for 2 or 3 ounces. Smaller amounts also less time to thaw…although this means you will use more bags. Also, don’t drop them once they are frozen, which can also contribute to leaks.
