This is a wonderful opportunity chance for them to help you with the sick child like bringing a drink of water and asking if there is anything you can bring the sick child like a book or toy. You could also emphasize the importance of hand washing and how germs are spread! Bringing lunch on a tray is always fun for both server and recipient! Your healthy child could make a "Get Well" card!
