A Step-by-Step Guide to Storing Breast Milk: NHS Guidelines
Introduction to Storing Breast Milk
As a new mum in the UK, understanding how to store breast milk safely is crucial to ensure your baby receives the best nutrition possible. According to NICE guideline CG30, breast milk can provide optimal nutrition for babies.
Step-by-Step Guide to Storing Breast Milk
Step 1: Expressing Breast Milk
Before storing breast milk, you need to express it. You can do this by hand or using a breast pump. If you're using a breast pump, make sure to follow the manufacturer's instructions. I recommend washing your hands with soap and warm water before starting, and expressing in a comfortable, quiet space, like a nursery or bedroom.
Step 2: Storing Breast Milk in the Fridge
Once you've expressed your breast milk, you can store it in the fridge for up to 5 days, according to NHS guidelines. Make sure to label the container with the date and time you expressed the milk, using a marker that won't smudge, and store it in the back of the fridge, where it's coldest. The temperature should be around 4°C, which is the ideal temperature for storing breast milk.
Step 3: Freezing Breast Milk
If you won't be using your breast milk within 5 days, you can freeze it. Frozen breast milk can be stored for up to 6 months in a freezer at -18°C or below. Again, make sure to label the container with the date and time you expressed the milk, and consider using freezer bags or containers specifically designed for breast milk storage.
Common Mistakes to Avoid When Storing Breast Milk
There are several common mistakes to avoid when storing breast milk, including not labeling the container, not storing it at the correct temperature, and not using a clean container.
Avoiding Contamination
It's essential to avoid contaminating your breast milk to prevent the growth of bacteria. Always wash your hands before expressing and storing your breast milk, and make sure to use a clean container. You can also consider using a breast milk storage bag or container with a built-in sterilization system, like the ones available at most baby stores in London.

NHS Guidelines for Storing Breast Milk
The NHS provides guidelines for storing breast milk, including how to store it in the fridge and freezer, and how to thaw frozen breast milk. You can also find guidance on NCT and Tommy's websites, which offer valuable resources for new mums in the UK.
Storing Breast Milk at Room Temperature
According to NHS guidelines, breast milk can be stored at room temperature for up to 6 hours. However, it's recommended to store it in the fridge or freezer as soon as possible to prevent the growth of bacteria. If you're on-the-go, consider using a cooler bag with ice packs to keep your breast milk cool.
Thawing and Using Frozen Breast Milk
When you're ready to use your frozen breast milk, you'll need to thaw it. You can do this by leaving it in the fridge overnight or by running it under cold water. Once thawed, use the breast milk within 24 hours. I recommend thawing it in the fridge overnight, as this helps preserve the milk's nutritional properties and prevents bacterial growth.
Mixing Breast Milk from Different Days
According to NHS guidelines, you can mix breast milk from different days, as long as it's been stored safely. However, it's recommended to use the oldest breast milk first to ensure it doesn't go to waste. You can also consider labeling your containers with the date and time you expressed the milk, so you can easily keep track of which ones to use first.
Conclusion and Next Steps
Storing breast milk safely is essential to ensure your baby receives the best nutrition possible. By following these steps and NHS guidelines, you can store your breast milk with confidence.
