Most parents tell me that their elementary school child has 20 to 25 minutes to enter theĀ school cafeteria, Ā search for her lunchbox buried in a portable tub, find a place to sit, open all the containers, eat (oh, right, eat), then clean and pack up before the bell rings.Ā In an effort to ensure that their kids eat anything at all, well-meaning parents pack lunchboxes filled to the brim with typically, 7 to 8 different options!
