This book is designed to assist parents and teachers to sincerely and positively support the healthy development of diverse, biracial and biethnic children. The book's purpose is also to extend the concept of diversity and multicultural education to include the unique needs, histories, and experiences of interracial and interethnic families and their children. Chapter 1, "The Development of Healthy Biracial Children," discusses two of the most difficult issues facing interracial families: the identity of their children, and how to handle the problem of a lack of a category for their children on census and OMB forms and documents. Chapter 2 presents specific ideas for parents with children of mixed heritage--biological, adopted, and blended. The ideas were specifically developed to help support these families and children. The ideas suggest ways for parents to help in their child's racial identity development and to work with teachers and other professionals. Chapter 3 gives specific information to families who adopt multiracial and multiethnic children, and to child care programs and schools who serve adopted biracial and biethnic children, both domestic and foreign. Chapter 4 addresses some general ideas to help programs working with multiracial and multiethnic families and their children to become responsive to the needs of these families. Chapter 5 covers interracial and interethnic families and biracial and multiethnic children whose combined heritages are not Black/White. The book's final chapter explores many of the myths that exist about interracial and interethnic relationships, interracial families, and children of mixed heritage.
