Early intervention for infants and toddlers: Applications for pediatric oncology.

Young children (<3 years) with cancer are at risk for delays in development due to their disease and its required treatments and restrictions. In the United States, Part C of the Individuals with Disabilities Education Act describes a system of early intervention (EI) services for young children with delays or the potential for delays in development. Children with cancer may be eligible for EI but are rarely referred. Our objectives are to describe the critical impact of early childhood development on long-term outcomes, review current considerations for EI, and advocate for the referral to EI for young children with cancer.
