Simultaneous bilingualism describes a situation in which a child learns more than one language from birth, meaning they are spoken to in both languages on a regular basis. If this occurs throughout the final stages of language development, the child will be able to fluently speak and understand both languages; both languages are considered the child’s first speaking language.

The difference between the sequential and simultaneous bilingual comes down to the difference in whether or
