DEVELOPMENTAL MILESTONES
An understanding of child development is foundational knowledge for pediatric occupational therapists. Occupational therapists want to know what developmental changes occur in children and how children develop their
unique personhood. The answers to these questions provide essential knowledge for evaluating children and for determining the appropriate materials, activities, and environments to support children’s skill development and participation in their communities. Identifying children with developmental deficits or significant delays remains an important function of physicians, nurses, occupational therapists, and others who
provide early intervention services.
HOW DO CHILDREN DEVELOP NEW PERFORMANCE SKILLS?
- Motivation and self efficacy
- Temperament and emotional development
- Risk and resiliency
CONTEXTS FOR DEVELOPMENT
- Cultural
- Physical
- Social

WHY IS IT IMPORTANT?
The development of occupational performance is influenced by many systems and variables in the individual child and in the environment. The various patterns observed in children provide insight into how and why a child follows a certain developmental trajectory.
Sensory, motor, cognitive and social skills support the child’s performance in play occupations. At the same time, a child’s activities are highly influenced by his or her cultural, social, and physical contexts.
