. . . Dr. Xiao-Lei Wang, a professor at Pace University in New York, says that young children can be exposed to many languages at once. Exposing children to more than one language as early as possible may ensure native-like proficiency in these languages. “Human capacity for language acquisition at an early age is unlimited,” Wang says. “However, practically speaking, it is more realistic and manageable for parents to raise children with two or three languages successfully in the home environment.”
According to Wang, one reason for focusing on only two or three languages is because a child needs a sufficient input to acquire a language (it has been suggested that at least 25% input is necessary to acquire a language). She also says that to form a habit of communication in a given language in early childhood, parents need to speak consistently to a child in that language.
