Interesting, I thought.
From an 'economist' blog:
"Many parents once believed that a second language was a bad idea, as it would interfere with developing the first and more important one. But such beliefs are woefully out of date today. Some studies (such as this one) seem to show that bilinguals have smaller vocabularies in each language (at early stages) than monolinguals do. But other studies (such as this one) find no vocabulary shortfall in either language. In any case, the influence of mono- or bilingualism on vocabulary size is later overtaken by the importance of education, socio-economic status, reading and writing habits. In short, there is little evidence that raising a child bilingual will hurt their primary language."
