Early research on literacy development usually focuses on children in preschool or kindergarten. Few studies have examined the early literacy of bilingual children. This study examines its relationship with different family learning environments (e.g. book availability), and family learning activities (e.g. reading books, telling stories, and singing songs) of bilingual and monolingual children from 9 months of age to kindergarten entry. The Early Childhood Longitudinal Study-Birth Cohort was used as the analysis sample. We included 1300 bilingual children and 5150 English monolingual children. We uncover that bilingual children generally lag behind in both resources and frequency of family learning activities. Using various decomposition techniques, we show that early reading score differences between bilingual and monolingual children can be explained by differences in resources and early family learning environments.
