This series supports interventionists (speech/language, occupational and physical therapists; psychologists and other mental health providers; early intervention providers; preschool teachers and other providers) working with young children (birth through kindergarten) with diagnosis or profiles consistent with autism spectrum disorder. We will discuss strategies from Naturalistic Developmental Behavioral Interventions (NDBI) such as the Early Start Denver Model and others, plan for the intentional use of these strategies in practice, and work through difficult situations. Significant focus is on supporting families to use these strategies in their daily lives.
