The maximum duration for storing breast milk in a refrigerator is up to 4 days. This guideline is based on research and recommendations from health organizations regarding the preservation of the quality and safety of breast milk. Storing breast milk in the refrigerator helps maintain nutrients and enzymes while minimizing bacterial growth, which can occur when milk is not stored properly.

When expressed breast milk is kept at temperatures of 4°C (39°F) or lower, it can be safely consumed within this 4-day window without significant risk of spoilage or contamination. Beyond this time frame, the quality of the milk may degrade, and the potential risk of harmful bacterial growth increases, which is why the recommendation emphasizes this specific duration.

Understanding this guideline is crucial for parents and caregivers to ensure that infants receive the highest quality breast milk, thereby supporting their nutritional needs and overall health.
