Single-parent families. Blended families. Gay or lesbian-parent families. Traditional families. Grandparents raising grandchildren. There are so many types of families today, all of them with their own challenges. Are nontraditional families new? Or did they exist throughout history in some form or other? And what makes some families strong, while others struggle? Are some families so nontraditional that they can't really even be considered families? These are some of the questions this book addresses.
