Variations in the quantity and quality of input bilingual children hear account for individual differences in language learning. Some sources of variation in quality of input are related to the parents’ language background (Place & Hoff, 2011; 2016). The parents’ language background determines the sources of children’s exposure to English, how frequently children hear a language in the home, the richness of the English language environment, and access to native speakers of each language in the home (Hammer, Davison, Lawrence, & Miccio, 2009; Place & Hoff, 2011; Place & Hoff, 2016; Paradis, 2011). The present paper examines the effects of parents’ language backgrounds on bilingual children’s language outcomes. We followed 120 bilingual Spanish-English speaking children from 30 to 54 months, with language outcomes in both languages at both time points. We examine the effect of the number of monolingual speakers of each language in the home, the amount of input from native and nonnative speakers of each language, and parent language proficiency in each language. Our findings have theoretical implications for understanding how parents’ language backgrounds and nonnative input in bilingual homes affect children’s language development in each of their two languages and practical implications for offering advice to families raising children who hear more than one language.
