As researchers have shown, context is also incredibly important to the acquisition of bilingual vocabulary. Speaking with children in different languages in different contexts will allow them to gain a more full vocabulary in each language. Furthermore, increasing the number of people children interact with in each language will provide them with more opportunities to learn in varied contexts. Study has provided evidence against the popular "one-parent-one-language" approach, as it restricted the contexts a child had for interactions and use of that language.
