This practical resource offers a complete program of exercises and activities based on an innovative relationship-based approach to encouraging cognitive and social development and interaction in children with autism and other 'late-talking' conditions. The Adult-Child Relationship Map (ARM), first described in Communicating Partners: 30 Years of Building Responsive Relationships with Late-Talking Children, forms the basis for identifying the strengths of both child and life partner and setting developmental goals. MacDonald provides effective guidelines for establishing a social play habit, developing home-based routines, including conversation routines, and setting up a daily activity diary. Schools and group settings are also covered. This resource is an essential tool for parents and professionals helping children with autism develop more effective social and communication skills.
