1. Can Breast Milk Be Refrigerated?

The answer is: Yes. Breast milk can absolutely be stored in the refrigerator. In fact, refrigerating pumped breast milk not only allows moms to be more flexible with feeding schedules, but also helps retain most of the milk's nutrients—if stored properly.

Pediatric experts and the World Health Organization (WHO) recommend refrigerating breast milk immediately after pumping, especially when mothers are working, away from home, or unable to nurse directly.

2. How to Properly Store Breast Milk in the Refrigerator

To store breast milk effectively, keep the following in mind:

2.1. Use the Right Storage Containers

  • Choose BPA-free plastic or glass containers made for breast milk storage.
  • Specialized breast milk storage bags are also a great, hygienic option.
  • Label each container or bag with the date and time it was pumped for easy tracking.

2.2. Seal Tightly

Ensure the lid or bag is tightly sealed to avoid air exposure, contamination, or nutrient loss.

2.3. Store in the Right Spot

  • Avoid the fridge door where temperature fluctuates.
  • Place the milk in the back of the main compartment, where it stays coldest and most stable.
