The advantages of raising bilingual children far outweigh those of limiting children with the possibility of a bilingual social education. Bilingual children, for example, often exhibit a greater capacity for flexible thinking. Since even the most distinct languages are related in some way, learning two languages simultaneously adds, rather than subtracts, and focuses, rather than distracts, one’s understanding of one language. Grammatical competency often takes longer for bilingual children, but that doesn’t mean they are confused or aren’t learning as well as their monolingual peers. Bilingual children are simply learning more information, necessitating a slower pace. Because a felt need for the use of language is so crucial to learning languages, this slower pace is not a social inhibitor for bilingual children. No, the difficulty arises in creating and sustaining learning environments (namely non-forced social situations) in which the child is amply exposed to both languages and exhibits a relatively equal level of felt need for both languages.
