Bilingualism is the ability to communicate in two different languages.
Language acquisition is very similar for monolingual and bilingual children, although some experts view bilingualism as a specialized case of language development.
Simultaneous bilingualism occurs when a child learns both languages at the same time.
Sequential bilingualism occurs when children use their knowledge of and experience with a first language to rapidly acquire a second language.
Research indicates that there are numerous advantages to bilingualism.
