Reusable vs Disposable Breast Milk Storage Bags
Before deciding whether to use reusable or disposable breast milk storage bags, consider how frequently you’ll be using the bags and what you’ll need to use them for.
What Are Breast Milk Storage Bags?
Breast milk storage bags are designed for the safe and easy preservation and storage of your breast milk.
They’re slim and light, so they take up much less space than other containers in your fridge or freezer, especially if you are planning to freeze and store a lot of milk in preparation for going back to work.
They’re also hygienic. You can be assured every time you use a new bag that it’s sterile and safe to use for your baby’s milk.
Are All Breast Milk Storage Bags Disposable?
Most breast milk storage bags on the market are for single use only. After they’ve done their job storing your milk and you’ve fed your baby, they’re thrown away.
Most storage bags are not designed to be washed, sterilized and reused. The reason for this is safety. Breast milk, like any food product, is susceptible to bacterial contamination.
It’s generally considered safest to use these bags once to collect your breast milk, freeze it and store it, defrost it into a bottle, and then dispose of it to reduce the chance of any bacterial growth.
What Are Reusable Breast Milk Storage Bags?
As we all look to reduce our reliance on plastic, some parents may want to find an alternative to the single-use disposable breast milk storage bag.
Recyclable storage bags are an option made of plastics that are easy to recycle along with your other recyclables.
Reusable breast milk storage bags are also available; however, you may find that you will use these differently than you use traditional single-use bags.
Reusable bags are made of silicone. They’re sturdy, thick, leak-proof, and easy to clean and sterilize. When your baby is weaned, you’ll also be able to use these for so many other purposes in your kitchen.
Although these reusable bags sound like a great alternative, their cost makes them impractical if you’re building up a long-term supply of frozen milk. They’re also thick, so they take up a lot more storage space than single-use plastic bags.
Finally, reusable bags may be just what you’re looking for if you’re storing breast milk for short-term use on a daily basis. If you need to store breast milk for a long-term frozen supply, you won’t really be using and reusing bags. They’ll just be taking up space in your freezer.
What to Look for in Breast Milk Storage Bags
Although it may seem like a simple product to shop for, if you’re breastfeeding and pumping, there are a few things you’ll want to check when you’re choosing breast milk storage bags.
| Leak proof seal |
|
| Ability to pump directly to the bag |

|
| Shape for storage |
|
| Compatibility with pump |
