So, what are the Best Breast Milk Storage System?

When it comes to breast milk collection and storage, we can happily say moms have MANY options to choose from. Each product is suited for mom and baby’s lifestyle and storage situation. Here are some options:

 

Take note whether each product can or cannot be used in a freezer or which product may work best in just the refrigerator. If you are unsure what products are suitable for each use, feel free to reach out to us directly, we’re here to help!

WRITE IT DOWN

Once you’ve arrived at your preferred breast milk storage system, consider developing an easy, yet effective way to memorialize the dates you expressed your milk, as well as the dates you froze and refrigerated your milk. This can be as easy as adding a waterproof label to each bag or bottle, or creating a numbering system that corresponds to a written calendar or list.

Many bags have a section for mom to write what day and time she expressed the milk. Storage and collection bottles and caps can also be written on for date and time of expressed milk.

KEEP IT CLEAN

Before expressing breast milk, make sure to wash your hands with soap and water. It may seem like an afterthought during those sleepless nights and hectic days, but proper handling and storage of breast milk is key to its shelf life.

Make sure your breast pump accessories, as well as your storage containers, are cleaned properly before use as well.

How long will breast milk last in a fridge vs freezer?

Per Center of Disease Control and Prevention guidelines, newly expressed or pumped breast milk can be stored:

  • At room temperature (77°F or colder) for up to 4 hours.
  • In the refrigerator for up to 4 days.
  • In the freezer for about 6 months (best); up to 12 months is acceptable.
  • In an insulated cooler with an ice pack for up to 24 hours.

 

Do not place your breast milk storage bags or bottles in the refrigerator or freezer doors. These areas are prone to temperature fluctuations, so a storage spot in the back of each unit is best.

Fill your storage containers with breast milk suitable for one feeding. These levels will fluctuate as you adjust to your little one’s ever-changing feeding schedule and appetite.


I got a Spectra S2 plus through 1 Natural Way. It's the same pump that I used with my daughter a couple of years back and it's the best. Helped increase my milk production and gave a very comfortable pumping experience. Thank you 1 Natural Way for very fast and smooth transaction. I received my pump just 5 days after I placed my order. Way to go!

THAWING FROZEN BREAST MILK

With your handy labeling or ordering system, you’ll be able to locate the oldest breast milk in your freezer. This breast milk should be thawed out first!

Here are a handful of ways to thaw/warm your breast milk while it is still in its original storage container:

  • Move to the refrigerator to thaw overnight.
  • Place it in warm water.
  • Run it under a stream of lukewarm water.

DO NOT thaw frozen breast milk in an oven, on a stove in boiling water or in a microwave!

Use breast milk within 24 hours of thawing in the refrigerator (no longer frozen or completely thawed). Once fully thawed, breast milk may be kept at room temperature for no longer than two hours
