|Medela Pump & Save Storage Bags|
I am not a fan of the Medela Pump & Save Breast Milk Storage Bags.
I've only used about 15 bags, and of those bags, I'd say 4 or 5 of them have leaked. The way I usually defrost the milk is place the bag in a cup of hot water. Before I realized that these bags tend to leak, I'd just leave it the water until the milk was defrosted. The first time I had a leaky bag, I ended up with a cup of hot watery milk as the milk had defrosted and leaked completely into the water. Now I just need to keep checking on it to make sure it's not a leaky bag, and if it is, then I need to defrost it in another bag in the water. Only once did I catch the leak before putting the bag in the freezer, and never have I had a mess in the freezer, so maybe a tiny hole breaks during the freezing process?
Once I left a bag in the fridge overnight to defrost it (fortunately I had put it in a mug), and in the morning the bag was empty and the mug was full.
One nice thing about these bags is that you can connect them to your Medela pump and pump directly into the storage bag. That's nice. (I never did it, but I assume it works fine...of course, if the bag is leaky, then that would be one heck of a mess....)
