How to store breast milk in fridge

Storing breast milk correctly in the fridge is essential for maintaining its quality and safety. Freshly expressed breast milk can be stored in the refrigerator for up to four days. This duration helps ensure that your baby receives the necessary nutrients without the risk of spoilage.

When storing, it is crucial to use clean, sterile containers. Look for BPA-free bottles or breast milk storage bags specifically designed for this purpose. Always label your containers with the date to keep track of freshness.


It’s also vital to keep your refrigerator at the appropriate temperature. Ideally, maintain it at or below 40°F (4°C). Store the milk towards the back of the fridge, where it’s coldest, and avoid placing it in the door, as temperatures can vary there.

Best practices for storing breast milk

  • Use sterilized containers: Only use clean containers made for breast milk storage.
  • Date your milk: Always label your milk with the date it was pumped for easy reference.
  • Avoid overfilling: Leave some space in the container as breast milk expands when frozen.
  • Keep away from substances: Avoid storing near raw meat or other items that can contaminate the milk.
  • Know when to discard: Discard any milk not used within four days of storing in the fridge.

Reheating breast milk safely

When it comes to reheating stored breast milk, it’s essential to do it safely. Avoid using the microwave, as it can create hot spots that may scald your baby. Instead, opt for:

  • Warm water bath: Place the container in warm water for a few minutes.
  • Bottle warmer: Invest in a bottle warmer specifically for reheating breast milk.

FAQs about breast milk storage

How long can breast milk last in the fridge?

Breast milk can be stored in the refrigerator for up to four days. If you’re unsure it will be used within that time, consider freezing it instead.

Can I mix freshly expressed milk with refrigerated milk?

You can mix freshly expressed milk with refrigerated milk, but ensure both are the same temperature before combining them.

What if I accidentally left breast milk out?

If breast milk is left out at room temperature for more than four hours, it’s best to discard it to ensure your baby’s safety.


When to dispose of stored breast milk

Be aware of how to recognize if your milk has spoiled. Although breast milk has a longer shelf life than many other foods, it’s important to check for sour smells or changes in appearance. Spoiled milk can cause gastrointestinal discomfort for your baby.

Always remember, quality and safety are priorities when storing breast milk. Follow these guidelines diligently to provide your little one with the best nutrition possible!
