5 Mistakes Moms Make When Storing Breast Milk (And How to Avoid Them)
Storing breast milk isn’t as simple as just popping a bottle into the fridge and calling it a day. Whether you’re building a freezer stash for returning to work or just trying to make midnight feeds easier, avoiding common storage mistakes can help you protect every drop of that liquid gold.
Here are five mistakes many moms make when storing breast milk—and exactly how to avoid them.
Overfilling Storage Bags or Bottles
The mistake: Filling bags or bottles all the way to the top can lead to spills, leaks, and even bursting when the milk expands in the freezer.
What to do instead: Leave a little space at the top of each bag—about an inch is perfect. This gives your milk room to expand without making a mess.
Not Labeling with the Date
The mistake: Tossing bags into the freezer without marking the date can lead to confusion and wasted milk down the road.
What to do instead: Always label bags with the date (and time, if you're being extra cautious). Use the oldest milk first and follow the “first in, first out” rule to avoid spoilage.
Using the Wrong Storage Containers
The mistake: Reusing disposable bottle liners or generic bags that aren't made for breast milk storage can lead to leaks or contamination.
What to do instead: Use containers or bags specifically designed for breast milk. They’re pre-sterilized, durable, and made to preserve nutrients safely.
Letting Milk Sit Out Too Long Before Storing
The mistake: Getting distracted and forgetting to refrigerate or freeze milk in time can reduce its freshness and safety.
What to do instead: Follow proper breast milk storage rules:
-
Room temp (up to 77°F): Use within 4 hours
-
Fridge (40°F or lower): Use within 4 days
-
Freezer (0°F or lower): Best within 6 months (safe up to 12)
Wasting Freezer Space with Bulky Bags
The mistake: Tossing bags flat into a jumbled freezer pile makes it hard to organize—and can take up way more room than necessary.
What to do instead: Use our Freeze It Flat. It freezes bags flat and stackable, helping you save space and stay organized while building your stash. (It’s a total game-changer for small freezers!)
