Directions for Lansinoh Breastmilk Storage Bags:


Always flay flat when freezing bags. Fill up to 6oz / 180ml per bag. To preserve freshness, squeeze the air out of the bag before sealing. Ensure the bag is completely sealed by running your fingers along each zipper.

To thaw, place the sealed bag in warm tap water. Do not put in boiling water, microwave, or on a stovetop. Save time by pumping directly into bags in 2 ways:

Option 1, using Lansinoh pumps, attaches the bag to the expression set and pump directly into the bag. Option 2, using most standard size pumps, use Lansinoh Pump Adapter to pump directly into bags. Adapter sold separately. Fits most Medela, Ameda, and Evenflo pumps.

Best With Thermal Sensors: 60 Thermal Sensor Breast Milk Bags

These breast milk bags feature most of the same options as other popular bags, but they stand out because each one is equipped with a thermal sensor that indicates when your breast milk is just the right temperature for the baby after defrosting. It will also let you know if it’s too hot, so you don’t have to worry about the baby getting burned.

The self-standing bags each hold up to 7 ounces of breast milk and are made from thick, BPA-free plastic. Customers say they seal well, don’t leak, and are a good value for the price.

What are breast milk storage bags?

Breast milk storage bags help free up space in your bottles and let you store breast milk somewhere (your fridge or freezer) for later use. They are unlike storage bags you’ve used for food (so you can’t substitute a plastic sandwich bag, for example). Breast milk storage bags are much thicker and are BPA-free and FDA-approved for the use of storing and protecting breast milk during transportation, thawing, and freezing.

Also helpful? “Most breast milk storage bags have an ounce or milliliter markers on the side to track the volume of milk you are storing and feeding, which can be especially helpful when you go back to work,” says Helen Anderson, a lactation educator and founder of Milkies Milk-Saver.

Choosing the best breast milk storage bags

When shopping for breast milk storage bags, it’s important to keep a few things in mind:

  • Make sure they’re made of food-grade plastic. This assures you that the manufacturer knows exactly what is in the bag’s plastic and that it is specifically designed for breast milk storage. 

  • Check for safety or tamper-resistant seal. A firm seal that you have to remove prior to use ensures that the bag is clean and uncontaminated.

  • Consider how it stores. A good breast milk storage bag will freeze flat and take up minimal space in your freezer.

If you’re looking to save time, consider bags that let you pump directly into them instead of bottles. This allows you to skip the step of transferring milk from bottle to bag (plus, you won’t have extra bottles to clean!).

Here are some of the most efficient and trusted breast milk storage bags that won’t leave you crying over spilled milk.
