Introduction
As a breastfeeding mother, it is important to store and defrost breast milk properly so that the milk stays safe and keeps its quality. In my practice as a midwife in Munich, I have advised many mothers who worry about storing and defrosting their breast milk correctly. In this article I will show you how to defrost breast milk safely in the fridge.
Why does defrosting breast milk properly matter?
Breast milk is the perfect food for your baby, but it can easily become contaminated if it is not stored and defrosted properly. It is important to store the milk at a temperature of 4°C or lower and to defrost it within 24 hours of expressing. Professional bodies recommend always storing and defrosting breast milk carefully so that the milk stays safe and keeps its quality.
Getting ready
Before you can defrost the breast milk, you need to prepare it properly. Here are some steps to follow:
- Express the breast milk into a clean, sterilised container. Make sure the container is big enough to hold the milk and that it has a tight-fitting lid to protect the milk from contamination.
- Label the container with the date and time the milk was expressed. This helps you identify the milk more easily later on and make sure it is not too old.
- Store the milk in the fridge at a temperature of 4°C or lower. Make sure the fridge is clean and hygienic to protect the milk from contamination.
How long can breast milk be stored in the fridge?
Breast milk can be stored in the fridge for up to 5 days. It is important, however, to defrost the milk within 24 hours of expressing so that the milk stays safe and keeps its quality. If you want to keep the milk for longer than 5 days, you should put it in the freezer.
Defrosting the breast milk
To defrost breast milk safely, you need to warm it slowly and evenly. Here are some steps to follow:
- Take the breast milk out of the fridge and let it stand at room temperature until it has defrosted. Make sure the milk does not get too warm, as this can affect the quality of the milk.
- Alternatively, you can defrost the milk in a water bath at a temperature of 37-40°C. This is a good way to defrost the milk quickly and evenly.
How long does breast milk take to defrost in the fridge?
Breast milk usually takes a few hours to defrost in the fridge. It is important, though, to check the milk regularly to make sure it does not get too warm. I remember a mother who defrosted her breast milk in the fridge and then found it had become too warm. She told me:
I defrosted my breast milk in the fridge and then found it had become too warm. I was so worried that the milk was no longer safe. But then I remembered the instructions I had been given by my midwife, and I put the milk back in the fridge to defrost.
It is important to check the milk regularly to make sure it does not get too warm.
