Less a resource for new co-parents--sharing responsibility for their children--than the story of Mimi (the author), Jeff (her ex), Barbara (his girlfriend, then wife), and Joshua (the ""co-child"") and how they manage their lives--boots, bedtimes, vacations, weddings, jealousy, negotiations, phone calls, renegotiations. Interspersed throughout are bits of advice (""be open-minded and learn from each other's ideas and methods,"" don't confuse normal, age-appropriate behavior like nightmares with divorce-related adjustment problems) as well as anecdotes from other parents who have joint custody of their children. How-to material--on ""Scheduling Toys, Clothes, and Money""--stresses flexibility, but without detailing or evaluating many options. One chapter takes on the premise of numerous professionals that children are best off in one stable home--ordinarily, with their mothers; that position, however, is far more effectively challenged by Mel Roman and William Haddad in The Disposable Parent (1978). Parents in the midst of joint custody arrangements might find comfort and support in this rambling chronicle of its difficulties and benefits--if little else.
