The author investigates the development of children raised bilingually or multilingually. Parents and caregivers completed a questionnaire, providing information on 36 children growing up with two or more languages. Their responses indicate that bilingual and multilingual children usually develop as well as their monolingual peers, and sometimes even better. Some drawbacks of early bilingualism or multilingualism, such as a slight delay in the onset of speech production or asymmetrical language competences, are compensated for by several benefits of early acquisition of two or more mother tongues and early contacts with two or more cultures.
