Reusable Breast Milk Storage Bags (2021 Reviews)

By Amanda Glenn, CLC. Last Updated January 17, 2021. Originally Posted June 3, 2020.

Most breast milk bags are made of plastic, are pre-sterilized, and are intended for a single use. After breastmilk is frozen and thawed in this kind of bag, the bag should be discarded. However, new reusable breast milk storage bags made of silicone are now an option, too!

When to Use Reusable Breast Milk Bags

Pros and Cons of Reusable Breastmilk Bags

Some of the advantages to using reusable bags include:

  • They don’t leak! They are very well-made and sturdy
  • Very eco-friendly
  • They are made of silicone and allow you to avoid using plastic
  • After you’re done breastfeeding, you can use it for other things (it’s similar to a Stasher bag with a slightly different shape)

The only real con is the price – reusable breast milk bags are more expensive than disposable bags.

Additionally, they might not work for all reasons you might want to freeze milk.

When to Use Reusable Storage Bags

Reusable bags obviously don’t make sense for building up a huge freezer stash – both because the price of the bags is too high, and because of the point of the bags is to reuse them.

So when does it make sense to use a reusable bag? Here are a few scenarios.

  • If you’re pumping breast milk at work and won’t feed it to your baby for a few days or more (say, you pump on Friday and your baby won’t use the milk until Monday), it might make sense to freeze the milk rather than store it in the refrigerator. If you do this every week, reusable bags make sense.
  • You are a “just enougher” (meaning you pump about as much as your baby needs each day) with a small freezer stash that you’re rotating.
  • You prefer to travel with milk (going to and from work, or on a plane) in bags rather than bottles, because they take up less room.

However, if you’re freezing thousands of ounces of milk so that you can wean early and keep giving your baby breastmilk until they turn one, it doesn’t make sense to use a reusable bag. You won’t actually be reusing the bag (because when you thaw and feed the milk, you won’t be pumping anymore).

Defrosting Breast Milk

Defrosting Reusable Breast Milk Bags

You can defrost breast milk in reusable bags the same way that you would in ordinary plastic bags – in the refrigerator, in cold water, or in warm water.

More on defrosting breast milk here.

You may also be use Junobie bags to defrost milk in plastic bags. Here are some stories showing how I did this:

Cleaning the Bags

Before cleaning a reusable breast milk storage bag, check the manufacturer’s instructions.

However, most bags can be hand washed in the sink (and then air dried) or washed in the top rack of the dishwasher, and they can be sterilized in the same manner as other breast pump gear.

Where To Get Reusable Breast Milk Bags

The only reusable breast milk bag manufacturer (that I know of!) is Junobie. They make super cute white, pink, and green breast milk bags made out of silicone.
