Description of Medela® CSF Bags

Medela's CSF Bags are used to collect, store and freeze expressed breast milk. The bags are presterilized for maximum hygiene and they attach directly to any Medela breastshield so you can pump right into the bag. No need for separate collection and storage containers. A built-in pouring spout can be torn open when it's time to empty the bag. The area for labeling each bag is outside the milk chamber to protect the purity of the milk. 50 per pack.
Being able to collect and store expressed milk for future use can be a great convenience and timesaver if you've chosen to breastfeed your new baby. For mothers who are using a manual breast pump, this pack of 50 CSF breast milk bags from Medela makes that process very simple. The bags are easy to work with: simply peel apart the top of the bag, insert a twist tie through the prepunched holes, and place the bag around the collar of the breast pump. After pumping and filling the bag and squeezing the air out, the top of the bag can then be folded over the twist tie to the level of the milk. By pulling the ends of the twist tie together you now have a neatly packaged serving of nutritious breast milk. The bags are puncture-resistant and sturdy enough for the freezer, and they come with measurement indicators in ounces and milliliters and a label where you can record the date and time you expressed the milk. Fifty twist ties and instructions are included. --Chris Burns

Baby Products Reviews of Medela® CSF Bags

Customer Review: designers at medela lack common sense
Summary: 1 Stars

i would give this a 0 star if there's a choice. i got a medela pis advanced at home and loved it, so i naturally assumed the storage bags would be superior to others. It's not that hard to use once you do it once, but complex enough to have an instruction sheet for new users. I came home from the hospital with a 2 day old baby, physically exhausted, dead tired, sleepy, and I have to hold up the 2 parts and read the instruction and figure out how to use it!! Before I get into the review, let me walk through the steps it takes to pump/store/use for this product: it's a bag that requires you to insert a wire into 2 holes on the bag, peel open the corner, fit it under the pump or pour milk into it directly, seal it by rolling the top a few times. Twist the metal wire to seal it. once frozen, you thaw it in the fridge over 6-12 hours, then twist open at the bottom.

Here's what's wrong with this bag:
- The steps seem simple enough, but it's for moms who have plenty of time, who are wide awake and alert at 2am and have 2 free and steady hands (who have the patience to insert a wire into 2 holes, peel the corner, and for storage must sloooowly squeeze out air and roll down the top of the bag and make sure there's no leakage), and able to do all this quickly under dim lighting at night. For me, i'm a busy mom (yes with only one baby, I hardly have time to eat or go to bathroom), I was severely sleep deprived in the first 4 months of my baby's life. Every minute becomes precious and since I pump 4-6x a day at the beginning, medela bags were a horrible addition to my busy life (btw pumping itself already took up an hour a day for me, not counting the time of washing bottles).

- 2 parts are involved in Medela, the metal wire, and the bag itself. My favorite brand, Lansinoh, has a simple double locked zip bag, you pull to open, pump into it, and seal/ store.

- Medela bags take up more space to store. it's practically a plastic bag with liquid in it, so it's almost spherical once frozen. The other brand I use (zip bags) can be laid flat and stacked on top of each other, saves freezer space

- Takes longer to thaw. Because medela has this unique thick shape that can't be easily stacked, it also takes much longer to completely thaw. The other brand I use is flat and thin, the thickness is about a third of an inch when laid flat, which means it thaws a lot quicker in the fridge, or if you put it under cool runny water it'll thaw in just a moment.

- The medela bag is 150 cc, my other storage bags can accomodate 180cc. Since it isn't cheap to store, I prefer to store 180cc at a time. My baby eats a lot more than that a day anyway.

- There's a little dent at the bottom of the medela bag so that you can peel open at the bottom to pour milk into a bottle. Theoretically it sounds simple enough, but in reality it isn't as graceful as it sounds. My fingers would slip, hard to gauge how much force to use so I either couldn't open it or ripped it with too much force and had milk splashing all over. Sometims doesn't work one way or another with my fingers, I had to use scissors. Either scissors or fingers, the problem of germs/bacteria contamination is in my head. The zipbags, on the other hand, is simple as open the zip lock at the top and pour.

- If you can't finish the whole medela bag, you can't restore the left over milk in that bag for rest of the day. Once the bottom is opened it's opened. the zip bags on the other hand can be re-sealed until you use it the next time (within 24 hrs)


In summary, the design of this storage bag is flawed, archaic and lack convenience for modern working women. If I were a mom years ago I'd probably appreciate this product. Now that there are other products available in the market that are clearly convenient and easy to use, I'm not even sure i want this product even if it's offered to me for free. I'm using Lansinoh and it's cheaper ($5.99 for 25 bags), and it saves me half the time. I don't have to juggle 2 different parts, piece it together, carefully roll down the top of the bag to prevent spills, etc. I also can handle a lot more bags in the freezer b/c it can be stacked easily. I haven't tried other brands besides Medela and Lansinoh, but I can't imagine any brands can be worse than Medela.
