There are several factors to consider when determining how to store breast milk, but the most important is when you plan to use it. Regardless, always use a clean, sterilized container, and label the container with the time and date so you can use the oldest milk first.
Conveniently, breast milk is suitable for refrigeration and freezing so when preparing to use it, an easy way to remember “the rules” is the Rule of Six.
Rule of Six
- Room Temperature Breast Milk is okay for Baby for 6 hours
- Breast milk is fine refrigerated (32°F) for 6 days
- In the Freezer (-1°F or lower) breast milk is safe for 6 months
As always, check with your doctor and/or lactation consultant for their professional opinion.
