one-parent one-language/Grammont's principle

[Betty Yu]

Hello all,

  I am curious if there is convergence in current research on the
usefulness (or not) of separating languages as a strategy for teaching
children more than one language (e.g., one-parent/one-language,
one-situation/one-language). Is there evidence that children really
become confused by mixed linguistic input given that there's evidence
that code-switching and other language mixing behaviors are quite
normal in bilingual communities? I'm especially interested in this
topic as it relates to children with language impairments.

Thank you for your attention.
