A look at the various problems that can arise when an adult child returns to the nest, plus suggestions on how parents can handle those problems. Since 1970, there has been a 52% rise (to 22 million) in the number of adults living with parents. One reason, say Okimoto and Stegall, is the high cost of housing coupled with low wages for entry-level jobs. Young, hitherto independent adults are sometimes forced out of the commercial housing market due to breakups in marriages or love affairs or because of a job loss or school failure. The book's message on handling these ""boomerang kids"" is simple: parents should be supportive, but they should treat the returnees as adults. To ward off conflicts, parents should establish agreed-upon guidelines that provide for their own privacy, well-being, and lifestyle. These may involve specific limits on telephone and family car use, when and where the young person can entertain friends, and (when feasible) payment for room and board. The authors (both family psychotherapists) waffle a bit on the touchy question of home-based sex. Special chapters are devoted to three-generational situations (adult returnees with kids), and how to handle a young adult whose return has been precipitated by mental illness, alcoholism, or drug addiction. The book is oversalted with case histories demonstrating numerous inter-generational conflicts and how they were handled. In sum: well written (Okimoto has authored several youth novels), but twice as long as necessary.
