During early childhood, most children in the United States achieve their developmental milestones; however, about 1 of every 6 children will have a developmental disability or disabling behavioral problem before age 18. Less than half are identified during early childhood. Occupational therapists and occupational therapy assistants work with families and caregivers to support and enhance young children's ability to engage in occupations appropriate to their age. This is a critical time not only to educate children but to also provide them with support to participate fully throughout their lives.
This publication addresses occupational therapy practice for children birth to age 5 years, including early intervention and preschool practice. It defines the occupational therapy domain, process, and intervention that occur within the boundaries of acceptable practice. Topics include prematurity, ASDs, feeding disorders, obesity, the NICU, and cerebral palsy, as well as motor and praxis skills, sensory-perceptual skills, emotional regulation, cognitive skills, and communication and social skills. Interventions discussed include those promoting social-emotional development; for feeding, eating, and swallowing; for improving cognitive development; for promoting motor performance; and for service delivery in early childhood. Appendices contain additional information relating to early childhood practice, coding for intervention and evaluations, funding sources affecting early childhood settings, and methodologies used in the evidence-based literature review.

Consideration of the evidence for all aspects of service delivery is a growing relevant concern of occupational therapists, including those providing early intervention to children and families. We conducted a review of the literature to uncover what evidence existed for determining the effectiveness of different service delivery models and methods used to improve occupational performance for children and families who receive early intervention services. Through a comprehensive search, we reviewed and synthesized studies, finding common themes of family-centered and routine-based approaches, service setting, and the inclusion of parent participation and training. Families consistently reported positive perceptions of family-centered and routine-based approaches. Parent participation and training resulted in positive outcomes. No specific setting or method of service delivery was identified as clearly most effective, with most studies reporting combined approaches and environments for interventions.
