How Do You Store Expressed Breast Milk?

Somehow I wound up with a dozen little plastic bottles for storing expressed breast milk—I think I got them free at the hospital where I gave birth. I preferred them over those little breast milk baggies that leaked all over the place. At the time I wasn’t concerned about BPA and other toxins found in plastic; I just didn’t know much about it. Years later, new mothers are concerned about using plastic for storing breast milk—but what’s a better option? Are there glass bottles that work well for freezing milk? What do you do?

  1. I use the Lansinoh storage bags. I thought about using glass mason jars, but they would take up too much space in the freezer. Also, you can squeeze out the excess air from the bags, which is supposed to help keep the milk from oxidizing.

  2. We use the Lanisoh storage bags for freezing too. We were looking for glass storage bottles but didn’t find anything good. The Evenflo ones don’t look like they have a really good seal on the cap.

  3. We use(d) the lanisoh storage bags for freezing, and the medula bottles for keeping in the fridge. Most plastic bottles that you buy these days are bpa free – and i think in some areas that is actually mandated by law.

  4. I use Lansinoh storage bags for the same reason as BB. If they are frozen flat they hardly take up any space. Plus I like to freeze small amounts since my kids are/were weird about the bottle and I obviously don’t want to waste any.

  5. We used mason jars and they were great! I didn’t need to store much milk, though, so space wasn’t an issue. Another reason I love the year long maternity we get in Canada — less need to pump!

  6. If I ever had a second baby (not too likely), I might try the mason jars! I work part time and don’t need to pump at work, so that might work. Sarah makes a good point: it’s easy to find BPA-free bottles these days. That would be my second choice.

    I’m surprised by how many of you use the plastic bags! They didn’t work for me at all–they really leaked all over the place. I also hated throwing them away. . . .

    I used the plastic bags, too, and bottles for the fridge. I agree with the others that the Lansinoh brand is the way to go. I tried another brand and hated them, but the Lansinoh never leaked on me!

  8. I used some plastic bags for the freezer and didn’t have a problem with leaking if I made sure to squeeze the air out and seal them tight. Also used the Medela bottles for the fridge. In addition, I used Sensible Lines Milk Trays for freezing: http://greenbabyshoppe.com/item_416/Sensible-Lines-Milk-Trays.htm. They were great because I could freeze 1-ounce portions and add a couple to a bottle if my son wanted a little more. It saved over having to defrost a whole bag when he only needed an ounce or two more. And on another note, they also worked great for freezing my homemade baby food into portion sizes!

    I hardly ever pump anymore but when my little guy was still tiny, I pumped for comfort (at first, we also pumped and finger fed him until we got the whole nursing thing down, too). I used the baggies and never had a problem with Medela or Lansinoh. I only froze 1-2 oz portions most of the time anyway because my son wasn’t too into bottles. It seemed like if I was going to be a little late for a feeding when I did leave him (which was not often), he would play with the bottle until I got home and then nurse. When I was running late once, he ended up drinking about 4oz and then nursing for 30 minutes when I got home right after anyway.

  10. My background is in chemistry, so I looked into the peer-reviewed science literature on this topic. Glass is the most non-reactive, however, some of the immunological agents (live cells, antibodies, etc.) stick to glass and therefore don’t get to baby. So I’m planning on freezing in glass (cells are killed anyway, so the stickiness issue doesn’t matter) and using plastic bags/bottles for refrigerator storage. However, since I’m returning to work and will need to have a long-term supply in the freezer in convenient portions, I plan to us the medela plastic storage bags.

    And, just to clarify, everything for feeding baby in the US SHOULD be BPA free by now. Usually the companies splash this all over the packaging.

  11. I froze milk in both glass bottles and milk bags. Both were Medela brand.

  12. My husband and I are expecting now and I have been looking into everything I can possibly find about being as green as possible with baby. After reading all the comments, I thought I would mention that I found something that I plan to give a try. They’re called Sensible Lines Milk Trays. They seem really nice, like ice cube trays but a different shape and measured out compartments with lids for easy flat freezer storage… http://www.sensiblelines.com/ or Google them. 🙂
