  • Check the dates on breast milk containers. Use newest breast milk (Last in first out/LIFO).
  • Heating up isn’t obligatory. Some mothers feed it in cold condition.
  • For frozen breast milk, move to refrigerator or a basin filled with cold water for one night. Slowly heat up the temperature to reach milk feeding temperature.
  • For breast milk in refrigerator, move to a basin filled with warm water or a pan filled with heated water for a few minutes. Do not directly heat up breast milk with stoves.
  • Do not heat up using microwave. Microwave won’t be able to evenly heat breast milk up. It could damage breast milk’s components and create heated parts that will hurt infants. Bottles might also break if it’s put in a microwave for a long time.
  • Shake breast milk bottle and drip on wrist to test the warmth.
  • Do not re-freeze thawed breast milk.


Freezing Up Breast Milk

  • Tighten bottle cap once breast milk has fully froze.
  • Leave about 2,5cm from the cap because breast milk’s volume will increase when frozen.
  • Do not store breast milk in refrigerator’s door or freezer
