The right breast milk storage bags can be a lifesaver for moms who pump to build their baby’s freezer stash. They should be easy to use, leak-proof, and most importantly pre-sterilized, so they can be popped in the fridge or freezer right away with minimal fuss. We looked at capacity, a wide mouth to make pouring easier, sturdiness, reasonable pricing, and other factors when selecting our top picks for best breast milk storage bags.
Our #1 pick is the Lansinoh breastmilk storage bags, which are made specifically to be used while you’re pumping and come pre-sterilized to save time and money. They lay flat, store, freeze, thaw, and pour well and are sturdy enough to carry around while you’re out of the house. We also love that they have a convenient spout for pumping directly into, so you can minimize mess.
These bags are a little more expensive than other options, but they have plenty of positive reviews from new and experienced moms alike. They’re large compared to most storage bags, which means you can store more at once and will save time having to transfer from one bag to another later on. Plus, they’re BPA-free and feature a convenient ounce marker on the front, which is perfect for new (and sleep deprived) moms who may not always remember exactly how many ounces they have.
These bags from Motif Medical are also a solid option for those who want to reduce their plastic waste. They have a wider mouth than most other storage bags to make it easy for you to pour in and out. They also come with a storage guidelines label that you can put on the outside of the bag to help keep track of your milk supply. In testing, they didn’t stack quite as flat as some of the other options we tried, but most women still give these bags high marks for their ease of use and affordable price. best breast milk storage bags
