The appropriate maximum duration for storing freshly expressed breast milk in a freezer is three months. This guideline is based on research and recommendations from health organizations that ensure the safety and quality of breast milk when stored. While breast milk can be stored in a standard freezer for longer periods, to maintain its nutritional and immunological properties, using it within three months is optimal.

Beyond this time frame, there may be a gradual deterioration in the quality of the breast milk, which can affect its benefits for the infant. Hence, while it might still be safe after the three-month mark, the efficacy of the milk may not be guaranteed. Understanding these storage guidelines is important for lactation consultants when advising new mothers on how to properly store and manage their expressed breast milk.
