Why Should I Buy Special Bags?
If you are like I was when I was a new mom, you might wonder why you can’t just use a ziplock bag that you would find in any grocery store. After all, it would be more convenient, and if you can store food in them, shouldn’t they be fine for breast milk?
Here’s why you should pass on the plastic baggies and opt for breast milk storage bags:
- They are different from ziplock bags – they are specially made to store breast milk.
- They are BPA-free, thicker and can be used to freeze, thaw and warm the milk.
- Breast milk storage bags are heavy duty and sterile, which means your baby has a smaller chance of getting sick from any stray germs.
- It’s much easier to pour milk out of a breast milk storage bag than it is a ziplock bag -- many of them have spouts just for that reason.
Breast milk storage bags are also not the same thing as the bottle bags that are sometimes used for feeding. Those bags are much flimsier and are not recommended for storing milk – they are only to be used for feeding purposes.
Why Can’t I Use Cheap Breast Milk Storage Bags?
You wouldn’t go shopping and pick out a pair of shoes simply because they are the cheapest ones in the store. You don’t want to pick out breast milk storage bags solely based on price either – you want to look for quality, and you need to ensure the ones you pick are meeting all of your needs. Even though they are all just bags, some of them have features that make them better than others.
This is why you should consider choosing high quality storage bags over cheap, inferior brands:
1. For the Reliability
Whoever made up that old saying, “It’s no use crying over spilled milk,” had clearly never pumped their breasts.
Nothing can cause a woman to feel like she is turning into The Incredible Hulk faster than a leak from a breast milk storage bag.
Pumping that milk isn’t anyone’s idea of a good time. To see a puddle of it on a refrigerator shelf is enough to bring out some serious rage in any woman. My screams of agony would echo around the world if one of my bags of breast milk went to waste.
2. For the Convenience
Superior bags have a design that makes it easy to pour milk into and out of these bags without spilling a drop.
As a new mom, it can feel like you’ve spent half your day pumping and you only end up with enough milk to fill a sewing thimble. So you want every last drop accounted for.
3. For the Safety
Unless you are a compulsive cleaner, your refrigerator can be a gross, nasty place. Just to be on the safe side, you want to make sure any breast milk you save is tightly sealed in a heavy duty bag to prevent any contamination from getting in.
You also need to label the breast milk with a date so you can toss any that has expired. The dates also help you rotate the stock in the refrigerator or freezer by allowing you to put the freshest ones in the back. Some bags have designated writing areas that are in an easy-to-spot location.
How Do I Use Breast Milk Storage Bags?
Before beginning to pump, you should wash your hands first, just like you would do if you were preparing dinner for your family.
After you’ve finished pumping, you take the milk you’ve collected and put it in a storage bag which you’ll either store in the refrigerator or the freezer. All you have to do is open your bag, pour the milk in and then remove the excess air from the bag before sealing.
You might be tempted to cram as much milk into one bag as you possibly can to get the most bang for your buck. You don’t want to do that, though. You should only put as much milk in one bag as you think your child will drink in one feeding. If you use 8 ounces of breast milk in a bottle and start feeding your baby, but he’s only able to drink 4 ounces at a time, you’re out of luck.
Once your baby has started feeding off that bottle, any extra breast milk in there needs to be thrown away – it can’t be saved. Once your baby’s saliva has mixed with the breast milk, it can’t be refrigerated again (source).
If your baby needs more than you’ve given her in one bag, you can simply add more milk to her bottle from another bag. Then you can reseal that bag and put it in the refrigerator again until you need the rest of it.
Another reason you shouldn’t overfill the bags is that if you plan to put them in the freezer, the milk will expand as it freezes. You don’t want to throw away bags that have popped open in the freezer because you were trying to overstuff them.
How Will I Know Which Bag is The Freshest?
You should label the bag with a date and time to make sure you know when it was pumped. If your refrigerator is anything like mine, things get shoved around, moved from shelf to shelf and jammed way in the back. It’s easy to lose track of which one is the oldest bag if you don’t label it. It’s a simple step that takes the guesswork out of milk storage.
If you plan to bring milk bags to a daycare or a childcare provider so your baby can have breastmilk while you are at work, you should also write your child’s name on the bag. I spent a year right after college working in a daycare while I looked for a job in my profession and it was unbelievable how many people would forget to put their child’s name on the bag.
At any given time in the daycare there were multiple bags of breast milk in the refrigerator, but there was no way to tell who they belonged to. Grab a marker and always write a name on bags you are taking outside of your house.

Our Top Pick Is...
Lansinoh takes the prize as my favorite breast milk storage bag. Despite our best efforts as moms and protectors of our breast milk, spill and leaks are a fact of life. They will occasionally happen with every brand out there. But the pourable spout and the patented double zipper seal makes leaks a rarity, not an everyday occurrence with these bags.
Lansinoh bags are the best all-purpose storage bag – they work well in the freezer when thawing out milk or for milk that is kept in the refrigerator. They don’t have that horrible plastic taste or smell. They hold a little more milk than some of their competitors, which is nice for when your baby’s appetite begins to grow.
