The shelf life of opened baby formula in the refrigerator depends on the type of formula and the manufacturer's guidelines. In general, most ready-to-feed or liquid baby formulas can be safely stored in the refrigerator for up to 48 hours after opening. However, it is crucial to check the specific packaging and instructions on the formula container for accurate guidance.
Powdered baby formula, on the other hand, may have a different storage duration after opening. Typically, prepared powdered formula should be consumed or discarded within 24 hours of preparation, even if it has been refrigerated. Once the formula is mixed with water, bacteria can start to grow, and the formula loses its freshness and safety.
Always follow the storage guidelines provided by the formula manufacturer, as they are designed to ensure the safety and quality of the product for your baby. If you have any doubts about the freshness or safety of the formula, it's best to err on the side of caution and discard it. The health and well-being of your baby are of utmost importance, so it's essential to handle and store baby formula properly.
