My baby hears two languages. Does their total word count compared to single-language babies end up being smaller?

In a bilingual baby, total language input is the same as in a monolingual peer, but the vocabulary is split between two languages. Research shows that when you combine words from both languages, bilingual babies' total concept vocabulary equals or even exceeds single-language children, and over time they have advantages in cognitive flexibility. Rather than comparing single-language word counts separately, it's more accurate to look at "combined conceptual vocabulary." So seeing fewer words in each language is expected, but overall language development doesn't lag—don't worry.
