A book filled with ideas for parents and teachers, this can also be used judiciously by anyone in contact with children -- from baby-sitters to camp counsellors. It deals primarily with those situations in which adult ingenuity can literally save the day. The gimmicks designed to amuse the convalescent child take into consideration limitations on mother's time and child's surroundings. A simple flashlight for instance can dispel doldrums for hours on end. Children's parties are usually nightmares for adults. Here are simple techniques for keeping the wreckage to a minimum without dampening party spirits. Quiet verbal games, ideal for car travel, simple finger plays for dissolving restlessness on trains and planes are invaluable to the parent on route. Rainy day projects involve more time and effort but will keep the housebound youngster from noticing the weather. Though a guide for baby sitters initiates the discussion, the book is generally aimed at the adult in charge of pre-school children and should find a permanent niche in their libraries, maybe their hearts too.
