Does anyone have any experience with bilingual twins? I speak in Italian to my husband and English to our 29 month-old twin boys. We live in Italy and my husband speaks in regional dialect to them... They don't talk yet (at least they don't say anything comprehensible) and I'm wondering if this is more due to the fact that they are twins or the fact that they are having to assimilate three languages. Or could both combined factors mean they won't be talking until they're about four or five ?
