Up until the last 10-20 years, it was thought that growing up bilingual was a disadvantage. However, recent research shows that bilingual kids outperform monolingual kids in a number of subject areas, including their schooling language. The cognitive benefits of bilingualism start as early as six months old, and continue throughout life, giving bilinguals distinct advantages in school and work. Today, over half of the world’s population is bilingual, and growing number of parents are getting their kids to learn two languages in the hopes that it will boost their academic and career prospects. Bilingualism, while a challenge early on in life, entails lifelong cognitive benefits that far outweigh the costs of teaching children a second language.
