How Long Does Prepared Formula Last
Prepared formula is a same-day handling item, not a vague pantry product. Track the bottle from the moment it is prepared, and treat the preparation time as the key reminder anchor.
Baby feeding and medicine items work best when the reminder is tied to the exact date, open date, or prep time that belongs to the product in use.
