Storing Breast Milk: Tips You’ll Want to Know

Clean Hands First: Always wash your hands before you start expressing or handling breast milk. It’s a simple step that makes a big difference in keeping things sanitary.

Pick the Right Containers: Go for breast milk-specific storage bags or food-grade containers with lids. Regular plastic bags or household bottles aren’t the best choice for storing breast milk.

Watch the Amount: Store about 2-4 ounces in each container. This way, you can avoid wasting any milk when you thaw it.

Label Everything: Write the date on each bag so you know exactly how long it’s been stored. This helps you use the milk within its safe time frame.

Leave Some Space: Make sure to leave about an inch of space at the top of the container. Breast milk expands when frozen, and this little extra room helps prevent spills.

Avoid the Fridge Door: The temperature on the inside of the fridge door is less consistent because of all the opening and closing. Store your milk in the main part of the fridge or freezer for a more stable temperature.

 

How Long Can You Store Breast Milk?

At Room Temperature: No more than four hours.

In the Fridge: Up to 6-8 days.

In the Freezer: 6-12 months is ideal.

After Thawing: Use thawed milk within 24 hours in the fridge, or 2 hours at room temperature.

 

Thawing Tips

Skip the Microwave: Microwaves can heat unevenly and might burn your baby. They can also destroy some of the nutrients in breast milk.

Thawing Options: If you need the milk right away, you can thaw it in warm water while it’s still in the bag. For a slower thaw, just put it in the fridge overnight.

One Last Thing

If your freezer has a hiccup and the milk starts to thaw but still has ice crystals, don’t worry! You can put it back in the freezer.

And if you’re ever in doubt about the milk’s freshness, give it a sniff. Bad milk has a pretty unmistakable smell.
