Definition
Occupational therapists provide services to infants, toddlers and children who have or who are at risk for developmental delays or disabilities. Occupational therapy is concerned with a child's ability to participate in daily life activities or occupations. Occupational therapists use their unique expertise to help children with social-emotional, physical, cognitive, communication, and adaptive behavioral challenges and to help children to be prepared for and perform important learning and school-related activities and to fulfill their rule as students. Through an understanding of the impact of disability, illness, and impairment on a child's development, plan, ability to learn new skills, and overall occupational performance, occupational therapists design interventions that promote healthy development, establish needed skills, and/or modify environments, all in support of participation in daily activities.
