The purpose of this study is to test the feasibility and efficacy of intervening with 2-year-old children with elevated temperamental Fear and/or Shyness or 3-year-old children with elevated anxiety and their parents, using a parent-child Cognitive Behavioral Therapy (CBT) protocol to reduce anxiety disorders and maintain reduced anxiety at one-year follow-up. Before the COVID-19 pandemic, study visits and treatment sessions were conducted in office. Now all visits and treatment sessions are conducted remotely.

• The parents are able to speak, understand, and read English
• The child must have a working knowledge of English.

Exclusion Criteria:

• Autism Spectrum Disorder (ASD) or global developmental delay in the child
