A new study has discovered that children of bilingual families do not experience greater problems learning language skills.

Linguistic expert Marit Korkman found that parents do not have to restrict a child's environment to a single language. Naturally, their vocabulary grows slower in each language, but that is only because they learn twice as many words.

Her research showed that bilingualism is no impediment to language mastery, and this also goes for children with learning difficulties or speech impediments. Four hundred bilingual children participated in the study, some with learning difficulties.
