Children with disabilities and developmental delays (DD) often face challenges within education systems, which are typically unprepared to meet their language needs nor equipped to support bilingualism because of the current early intervention (EI) workforce. Given this, the five-language domains framework can help bilingual EI educators to collaborate with caregivers in implementing research-based strategies to foster bilingual language development of young bilingual children within naturalistic environments. This paper provides research-based background information on the bilingual language of infants and toddlers with disabilities or DD and highlights how the five-language framework considers culturally appropriate practices and context.
