Hey there! So everything I read says the bags cause some of the antibodies in the breastmilk to be lost along the way (stick in bag, etc) and that plastic bottles cause some of the fatty milk to be lost. What bottles do people use?? I can’t even find options for bottle storage on amazon and when I do they’re only in like packs of 4 or so and seem like short term storage. I really want all the antibodies we can get
