How to Safely Store Breastmilk

How to Safely Store Breastmilk. Here's a how-to guide on how to safely store breast milk.

Whether you’re a nursing Mom returning to work, seeking a little bit of freedom to go out without baby in tow, or just want the option of feeding your baby a bottle instead of nursing, you might be wondering how to safely store your breastmilk, so that you maximize its nutrition and minimize waste.

After all, it is liquid GOLD!

If you’re like me and depend on your stored breastmilk to nourish your baby, read on to learn how to handle and store your breastmilk safely, according to the most up-to-date guidelines:

How to Safely Store Breastmilk. Here's a how-to guide on how to safely store breast milk.

Preparing to express/pump and collecting breastmilk:

  • Always wash your hands prior to expressing or handling breastmilk
  • When expressing/pumping milk, make sure to collect it in clean or sanitized bottles with tight screw caps, nursing bottles, or freezer-safe milk storage bags. Avoid using formula bottle bags or regular storage bags, as they tend to leak easily and don’t always seal properly.
  • Always label your bottles/bags with the date that it was expressed (so that you can use oldest milk first) and add your child’s name if you are giving the milk to a caregiver
  • Avoid adding freshly expressed milk to previously frozen milk (it’s best not to mix), and discard milk from a bottle that was fed but not finished (don’t put back in the fridge to use later).
  • Clean your pump supplies thoroughly after each use

Thawing Breastmilk:

  • Thaw frozen breastmilk by transferring it to the refrigerator, or by running the bottle or bag under warm water (or placing it in a bowl of warm water).
  • Do not use the microwave to thaw or heat breastmilk. Microwave ovens don’t heat every (this could lead to scalding the baby), and they can also damage the breastmilk and its nutrients.
  • Do not re-freeze breastmilk one it’s thawed.

Storing breastmilk:

Room temperature (counter/table):

Container should be kept covered and as cool as possible

  • Temperature: up to 77 °F or 25°C
  • Time: up to 6-8 hours

Insulated cooler bag:

Make sure that ice packs are in direct contact with milk the entire time and minimize opening the bag

  • Temperature: 5-39°F or -15 to 4°C
  • Time: up to 24 hours

Refrigerator:

Store at the back of the main compartment in fridge, where the temperature is the most constant.

  • Temperature: 39°F or 4°C
  • Time: up to 5 days

Freezer:

Store towards the back of the freezer where the temperature is more constant. Note that milk stored for longer periods of time (within these ranges) will be safe, however some of the fat within the milk may degrade, resulting in a lower quality.

  • Freezer compartment in fridge (older models)

    • Temperature: 5°F or -15°C
    • Time: up to 2 weeks
  • Freezer compartment of fridge (with separate door)

    • Temperature: 0°F or -18°C
    • Time: up to 3-6 months
  • Chest or upright deep freeze:

    • Temperature: -4°F or -20°C
    • Time: 6-12 months

I am going to be returning to work soon where I drive over an hour each way. Is it safe to refrigerate it after pumping at work. Transfer it home in a cooler and then freeze or refrigerate it when I get home?
