Lansinoh Breast Milk Storage Bags 50-pk.

I've tried a few other milk storage systems, including the medela bags (which you can pump directly into) and the hard plastic containers (like Avent). This is, by far, the most useful and most economical storage systemm.

Pros:
1. The bags have a double-zip closure. This ensures that the bag seals well and doesn't leak. Also, when you push the air out, a few drops of milk always slip out, but it usually doesn't get past the second zip-closure. The bags are superior to the hard containers because you can squeeze the air out and prevent freezer burn.

2. These lay flat! I put my warm bags of milk into a rectangular Tuppperware container and stack them up on top of one another. Then, I put them into the freezer, and they freeze perfectly flat, which the Medela bags don't do. Once they are frozen into flat blocks, I stack 10 blocks in a one gallon Ziploc freezer bag and label and date the Ziploc bag. This goes into the deep freeze...Read more

Initially, I liked the feel and function of these bags best of the brands I have tried, which include Medela and Gerber. After freezing, however, I had the same problem that other reviewers reported with the Lansinoh bags leaking at the bottom seams. I was quite careful to follow instructions about bag capacity and storing flat, and I defrosted gently in warm water, so I believe it to be a defect with the bag, not user error!

I emailed Lansinoh about my experience, and they were very apologetic and provided 100 bags free of charge via priority mail. While I am still a little nervous about using the bags, I now have the option of double bagging, which should help. I rate these bags a 3 because while leaking bags defeat the purpose and are a huge disappointment, it was an intermittent problem and I found the company to be very responsive to my issues with their product. I am hopeful that they will solve the leak problem in future.

I've used these for two babies now and have used the milk after 6mo in deep freeze.

They are great most of the time. I freeze about 10-12oz in each bag (yes, they say no more than 6oz, it's a myth). 12 is the maximum I found tho. The trick is to make sure there is no air. It won't leak b/c the bag will expand, unlike plastic storage containers. I use the straight edge of a table, push the milk all the way to the top and zip it as I push the air out. Don't worry if a little leaks out b/c it has a double zipper. Then I freeze it on a flat surface singly. After it's frozen, I put 8-10 of these in a big gallon zip lock bag and date the outside and put it in deep freezer. It's easier to organize them this way in deep freeze.

The bad thing about these bags is that once frozen, the plastic nicks easily if you drop it, scrape it against something, etc (as with all frozen containers). Lansinoh had really bad problem with leakage before but they've improved...Read more
