Breast milk is precious, and the last thing you want is to have it spill on the way from the freezer to your baby’s bottle. Using plastic baggies or disposable bottle liners for storage is against CDC guidelines and may lead to leaks and contamination, so it’s best to stick with a dedicated, leak-proof breast milk storage bag.
Reusable bags are thicker and sturdier than single-use options, and many come with a double zip lock to ensure that your liquid gold stays safe and dry. They also typically feature a wide mouth for hassle-free pouring and are designed to lay flat in the freezer to allow them to stack neatly. Some even have a labeling space at the top for easy identification.
Another reason to go with a reusable option is that it’s more eco-friendly than single-use breast milk storage bags. According to DeWeese, the plastic in landfills never actually decomposes but breaks down into microplastics over hundreds of years. It takes a lot of energy to recycle plastic, so using a reusable option is a better choice for the environment and your wallet.
