Durable Breast Milk Storage Bags for Pumping & Saving Every Last Drop

Breastfeeding isn’t always effortless: There are days when milk is plentiful, but there are also the days when milk isn’t as free-flowing. Pumping and dumping isn’t always an option, either: postpartum hormones can ignite feelings of guilt, or maybe you’re the type of mom who isn’t always around to nurse because of work or other obligations. In that case, rather than waste a single drop of nature’s nourishing formula for your baby, there are breast milk storage bags to collect and stow the excess. 

Breast milk that isn’t being used ASAP needs to be stored properly in order for it to stay fresh. According to the CDC, freshly pumped breast milk can be left on the countertop for four hours, stored in the fridge for up to four days and frozen for up to 12 months (though it is recommended that frozen breast milk be used within six months for optimal quality). Breast milk storage bags are made from food-grade, BPA-free plastic that come pre-sterilized in order to safely preserve the precious liquid. You can buy them in bulk or purchase as-needed — either way, you’ll want to check out the best breast milk storage bags to have on hand for your freezer stash.

1. Kiinde Twist Pouch Breast Milk

Toddlers love fruit and veggie pouches, and if you’re still supplementing solid foods with breastmilk, you and your child are bound to love these breast milk bags from Kiinde. The Twist Pouch is a three-in-one item that collects, stores and prepares breastmilk for feedings, but the best feature of this product is that you never have to transfer the breast milk into a bottle: the disposable breast milk bag can act as a feeding pouch so there’s no risky transfer of liquid. 

Kiinde’s all-in-one product is as sturdy as a traditional bottle, but as cost-effective as a disposable breast milk storage bag. It features a twist-lock component that offers leak-free, easy pumping, plus clear markings that measure how much you’ve pumped and how much has been consumed. Each pouch is recyclable and BPA-, PVC- and phthalate-free, so it’s safe for your baby and environmentally friendly.

2. Lansinoh Breastmilk Storage Bags

If you know for a fact that you’ll be freezing the milk you pump, Lansinoh has the product for you. These breast milk storage bags are specifically designed to protect your milk for long periods of time in the freezer, with ideal safety and preservative features to get the job done right. While some bags require an adaptor, Lansinoh offers moms the convenience of pumping directly into its bags. The bags themselves are super flexible and are able to stand or lay flat for compact storage. They also feature write-on labels for necessary markings, like dates, and include pour spouts for easy bag-to-bottle transfers.

But above all, what sets this best-selling breast milk bag apart from the rest is its double-zipper seal. This feature is meant to protect from leakage, while the additional reinforced double seal keeps milk optimally protected. Of course, the bags are also pre-sterilized, as well as BPA- and BPS-free.
