The Rule of Six and How to Store Breast Milk


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.

It’s a must to time your drinks, but if you’re pumping and storing your milk, the rules are a little more relaxed. You can also give your baby formula after you had a drink just to play it safe. In between having an alcoholic beverage and breastfeeding, you should wait at least three hours. If you’re having more than one drink, how long you have to wait depends on how much you weigh, what you drink, and how many drinks you’ve had, so make sure to plan accordingly beforehand.  You can also refer to our trusted Rule of Six.
