It is a rich, magical, finely wrought tome on childhood development. Intended for health care providers, the book is also well suited to lay parents who want to know more about their children. For teaching your young child how to resolve problems and conflicts with other people constructively, I recommend Shure's and DiGeronimo's Raising a Thinking Child . Shure and DiGeronimo use entertaining word games to help children become successful at recognizing differences, considering alternative behaviors, and taking into account both their own and others' feelings. For older children, there are many fewer books on the market.
Parents often leave the problem solving to schools.
This is very unfortunate, since the school-age years are the bridge to adolescence. The best overall reference I have read is Caring for Your School-Age Child , put out by the American Academy of Pediatrics as the second in their series. Like their volume about younger children, the first half discusses issues likely to arise at each age. The second half is again encyclopedic and gives practical information on such topics as poison ivy, car restraints, strep throat, chicken pox, etc. So Kids Will Talk .
