Storing Breast Milk

Always store your breast milk in a clean, preferably BPA-free, container. Breast milk can be stored at room temperature, in the refrigerator or in a freezer, depending on how soon you plan to use it.

For proper storage, label and note the date on each container. Always use the oldest milk first and don’t add fresh breast milk to already frozen milk.

To thaw your breast milk, simply put the container in a bowl of warm water or put it under warm running water for several minutes. You can also put it in the refrigerator to thaw. Breast milk thaws quickly. Never thaw frozen milk in the microwave because it can destroy valuable nutrients, and may burn your baby since the liquid heats unevenly. Do not refreeze breast milk once it’s been thawed.

Be sure not to save breast milk from one feeding to another; throw away any remaining milk.

Check with your provider or lactation consultant for specific guidance on breast milk storage.
