Do’s & Don’t’s Of Breastmilk Storage

  • On The Counter

- Always avoid direct sunlight. Store breast milk at the coolest location in your home. High temperatures could activate bacteria growth so avoid this at all cost.
  • In A Cooler Bag

    - 24 hours is the safest maximum amount of time for you to store your breast milk in the cooler bag. Always keep ice packs along with the milk in the bag and only open the cooler bag until its ready for use.
    • In The Fridge

      - Best location to store breast milk is in the center of the fridge, as far back as possible.

      • In The Freezer

        - Safest location to store breast milk is in the back of the freezer, where temperatures are more stable. Rule of thumb - FIRST IN, FIRST OUT. Always use the oldest milk first.

        Storing Expressed Breast Milk:

        1. Make sure breast milk storage bags or food-grade containers are clean and are made of either glass or plastic with air-tight lids/zips.
        2. Only use storage bags that are intended for storing breast milk to protect and keep breast milk fresh and healthy.

        Storage Tips

        1. Label, label, label!

        Always remember to clearly label the storage bag with the date it was expressed. And since its your journey, why not make it special and label the bags with little notes such as milestones, how you were feeling or little affirmations for yourself (emoji) on the storage bag.

        2. Doors are a no-no.

        Never store breast milk in the refrigerator door or freezer. This is where most temperature fluctuations occur.

        3. Pop it straight into the freezer.

        If you feel the breast milk won’t be used within 4 days. This will help retain the quality of the expressed breast milk.

        4. Travelling

        If you're travelling, breast milk can also be stored in an insulated cooler with ice packs. Depending on the quality of the insulated cooler, storage can be kept safe for up to 24 hours. Upon arrival, always store the milk in the refrigerator or freezer if milk is not to be used straight away.

        Freezing Tips

        1. To avoid wasting precious milk, try storing smaller amounts according to how much or what is required per feed for your child to drink. So if some of you face an oversupply, don’t dump all that milk in one big storage bag, mama! Practice this tip 👍🏻
        2. Because breast milk expands as it freezes, always leave about an inch of space at the lid/zip.


        Before you begin your pump session, always make sure your hands or those that are handling your pumps are clean.

        Inspect your pump and thoroughly make sure that the tubing is clean. Milk residue can cause mouldiness therefore affecting the quality of your expressed milk. Replace with new tubing immediately if mouldy.
