Summary: best bags for freezing and quick thawing
Comment: I breastfed my first child for nearly a year, and am now breastfeeding my second. I had tried several different types of freezer bags and these were the only ones that never leaked. I searched for slightly larger bags (these hold 5 oz) because my son was drinking 6-7 ounces a feeding but the ones I found leaked during thawing or warming. Medela bags are a great product.

Summary: 5 oz. capacity is too small
Comment: If you are like me and pump more than 5 ounces of milk per breast, these bags are too small. Although they can hold slightly more than 5 ounces, it is not recommended to exceed 5 ounces in order to leave enough room for expansion when the milk freezes. Rather than using two and sometimes three Medela bags, I find it easier to pump into the bottles and then pour the milk from both bottles into one larger storage bag (Lansinoh and First Years make larger bags).

Summary: Worth the money!
Comment: Great product!! When I pumped for my first child, I used a bottle to collect, then transferred to a ziplock baggie. This is SO much easier and more efficient. It has a handy method to attach to the pump, a place to write the collection date, and stands up for storage in the fridge. No more leaks and wasted milk! I'm getting more soon!

Summary: Miss the twist tie bags!
Comment: I have the Medela Pump in Style, and with my first son, I used the Medela storage bags with the twist ties. These were perfect! No storage problems, no leak problems. With my second son, I couldn't find the twist tie storage bags anywhere (stopped making them?) and instead found these bags. I have had nothing but problems! The tape does not hold very well, it is hard to tell if the ziploc is closed all the way (so I end up checking it at least five times before storing it, and another two times before warming it up), and I can't tell you how many times I have had these bags leak! With the old bags, if we accidentally dropped one on our hardwood floor, no problem. These bags explode like a cheap water balloon! And if they are frozen and you drop them, you can also create a leak which you won't even know about until you thaw the bag out. I wrote to Medela expressing my displeasure with their product, and the response I received was to call customer service with my problem. Thanks, but no thanks. I'm glad I'm almost done nursing.
