Selective Mutism (SM) is a highly impairing disorder which typically presents upon entry to school and affects approximately 0.7% of children. Despite its impact on social and academic development, it is a difficult disorder to treat and there is a small evidence base for behavioral treatment. Preliminary evidence suggests that behavioral treatment focused on exposure to social interactions, social skill building, and involvement of caregivers in treatment may be promising. This article presents two cases of early childhood SM to demonstrate the importance of tailored treatment implementation to meet the individual needs of each family and help children resume typical social development.
