Abstract: A method of identifying the day in which baby food containers are opened. The method includes providing a first set of markers and a second set of markers. Each of the markers include indicia indicating the day of the week. The markers in the first set of markers are distinguishable from the markers in the second set of markers by color or shape. The first set of markers are placed on opened baby food containers that include a known food, i.e. a type of food which the baby/child is not allergic to. The second set of markers are placed on opened baby food containers that include a food that is being newly introduced to the baby/child. The second set of markers serving as a safety device in aiding identification of food-induced allergies.

Abstract: A system for monitoring previously opened, metallically capped containers of baby food stored in a refrigerator for safe consumption thereof and/or allergic reaction thereto, by identifying each such container with a marker that magnetically adheres to the container cap and bears a preprinted legend identifying the day of the week In which the container was opened and stored. The first set of at least seven such markers, each bearing a legend identifying a respective day of the week, is preferably stored on a magnetizable board attachable to the refrigerator. An alternative system uses flexible plastic replacement caps each appropriately pre-marked with a day of the week.
