Title: Essential for pumping
Review: I have been using these bags since my son was just a couple of weeks old, and I am really pleased with their quality. I've had no leaks and it is easy to transfer the milk to and from the bags. Tip I wish I'd followed in the early days: freeze flat (but don't put too much milk in them). Also, don't rely on the measurements on the bag - they're not always accurate. Still, these are an essential item in my pumping bag each day, and I highly recommend them for moms who plan to be pumping a lot.
