<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">Just to add a word to this discussion: There is certainly no evidence that bilingualism in early childhood leads to real language delay - although the vocabulary size of bilingual children tends to be smaller in each language, while still being larger if the two are put together (see studies by Barbara Pearson, inter alia). <div><br></div><div>How could we possibly demonstrate that bilingualism leads to delay? Each child is different in rate of language learning; there is no way to know whether a child exposed to two languages would have learned more quickly if exposed to only one - but since bilingual children often have vocabularies of a very respectable size by age two (500 words or more in production, with a correspondingly good start on producing combinations), there is definitely no overall tendency for language delay - based on the many case studies published to date. </div><div><br></div><div>The question of the best advice for a multilingual family whose child IS seriously delayed (by which I mean very few words as late as 2.5 years and no word combinations) is something else again: I think the experts are divided on this one, but common sense suggests that consistent home use of just one language may be helpful for a child who happens to have difficulty with language learning.<div><br></div><div>One small bit of anecdotal evidence: I have just met the family of a child exposed to three languages from the start (English as the interparental language, Estonian from the mother and Spanish from the father), who had a number of clearly identifiable words at 9 months - which is remarkably early for any child, monolingual or not. This single example is enough to illustrate at least that real precocity in lang. dev. is not incompatible with multiple-language exposure. (Should we believe that this child was 'delayed' and would have had 10-20 words already at age 7-8 mos? I know of no reason to think so!)<br><div><br></div><div>-marilyn vihman</div><div><br><div><div>On 9 May 2011, at 12:04, parisa Daftarifard wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div>Dear Christophe,</div> <div>Thank you so much for your reply.
