After having one of my kids become seriously ill, keeping a spare bottle of antiseptic hand gel in the tool tray is important and critical. It is the best item to bring back health and you'll be glad you have it when you need it. I usually keep an extra energy drink in the tool tray also, in case of illness or old age, which drains the energy bar away fairly quickly. Like you, I use the fruit and candy rather quickly, my little people deserve all the praise I can give them.
