If you pump often, you’ll want breast milk storage bags that are durable and designed to stand up. Durability is a must to avoid leaks (especially with the bags sitting upright in the freezer). Look for thick, double-layered plastic or silicone, and extra qualifiers like a strong seal/closure, an oxygen barrier, and a wide opening that makes it easy to fill and pour.
If your goal is to build a large stash, you’ll also want to choose storage bags that can lay flat in the fridge or freezer and stack well. Many of the bags on our list feature a wide base that does just that.
When it comes to choosing the best reusable breast milk storage bags, the Lansinoh Breast Milk Storage Bags earn top honors because they have a special design that helps prevent seepage and make it easy to transfer from one bag to another. They’re a favorite among moms, and they have more than 90,000 positive reviews on Amazon. They’re pre-sterilized, easy to use, and a great value.
Another favorite among mothers, these resealable storage bags from Mommy’s Precious have a wide mouth and double-zipper seal that makes them very durable and leaking-proof. They hold up to 10 ounces of breast milk and have a space at the top to write down the date and amount. They don’t stand up as well as other bags on our list, but women love them for their durability and how they can store multiple ounces at once. best reusable breast milk storage bags
