I froze milk in 6 ounces. I’ve had more bags break upon thawing than I can count.

I wish I had read the reviews before purchasing this - it is extremely irritating and itchy, maybe because of very thin edge that get folder up easily.and the whole nursing pad unsticks and folds over very easily, which doesn’t prevent leaking. Don’t recommend.

Truly hate this nursing pad. There is nothing safe and dry about this pad. As a nursing mom that leaks heavily with every letdown, Ive tried every nursing pad under the sun. This one might be the worst. I really wonder if Medela even tested this with any real nursing moms before putting this on the market. First off, it has a hinged design that is completely unnecessary and makes it easier for leaks to occur. It make the pad look lumpy under your clothes, and when you pop open your nursing bra/tank to feed, it just folds right up and unsticks from your clothes and crumples up. Second, the absorbency on this pad is hysterically bad. Yes, it's ultra thin but I've had to change the pad multiple times a day and honestly period panty liners have better absorbency than this one.

When I used these I had no issues. I froze 4oz bricks and had no leakage at thaw

They worked as they should but they were too small for me.

Super uncomfortable and itchy. Would return if I could!

I pumped 5oz and put them in 2 separate bags, sealed them tightly and BOTH leaked out. Thought I hadn’t so I tried again and same thing! I was so upset to have lost all that milk! The only positive about these bags is that milk doesn’t stick to the insides so you get very little waste/residual that’s leftover in the bag. Nuk has a better seal but also has too much that sticks inside causing waste bc there’s no way to get it out

I bought it , it’s easy and no leak.
