Storing of breast milk

Breastmilk is very precious

You should store and thaw your breastmilk correctly. This is the only way you can be sure that all the important nutrients are preserved and bacterial contamination is minimised.

Guidelines for storing/thawing breastmilk

Medela recommends using the following guidelines for storing and thawing breastmilk. For Healthy Term Babies.

Room temperatureRefrigeratorRefrigerator freezer compartmentFreezer
Freshly expressed breastmilk Do not store at room temperature 3 - 5 days at approx. 4°C 6 months at approx. -16°C 12 months at approx. -18°C
Thawed breastmilk (previously frozen) Do not store 10 hours Do not refreeze after thawing! Do not refreeze after thawing!

Tipps for freezing/thawing breastmilk:

  • Never fill bottles/bags more than ¾ full to allow space for possible expansion.
  • Label the bottle/bag with the date you expressed the milk.
  • Do not store breastmilk in the refrigerator door. Store it in the lower back area of the refrigerator, where the temperature is coolest.
  • Thaw frozen breastmilk in the refrigerator overnight or hold the bottle or bag under running warm water (max. 37° C).
  • Shake the bottle or bag gently to blend any fat that has separated.
  • Do not thaw frozen breastmilk in a microwave oven or in a pan of boiling water (danger of burning).

What I Do

I am living my dream while working with mums and babies. I see mums when they are 34 weeks pregnant and then go to their homes once they go into labour. I stay for the full duration of the labour and after the birth I assist them with breast feeding. I do another visit after the birth to see that all is well and to help where I can.  Mums are always welcome to call me in the event that they have any questions, whether before or after the birth. I am passionate about my work as a doula and I care and love all the families with which I work. Once you have been present at a birth you feel part of the family and it’s wonderful to hear news of the new baby’s life as he or she grows.
