Storage tips

- Dry mixes keep sealed in the cupboard. Make up only what will be eaten at that feed, and treat anything mixed as a fresh food.
- Spoon a serving into a separate dish and feed from that, so the container stays clean.
- When in doubt, discard it; follow the label and your pediatrician first.
How can you tell if cereal (dry mixes) has gone bad?
- Any off smell, separation that will not stir back, or change in color.
- A bulging, leaking or damaged jar or pouch, or a lid that does not pop when first opened.

Shelf-life windows come from the USDA FoodKeeper, published by the USDA Food Safety and Inspection Service (public domain); we vendor the FSIS FoodKeeper dataset and refresh it in place. These are quality estimates, not food-safety determinations or guarantees: actual condition depends on storage and handling, and harmful bacteria may not have obvious signs.
