Advantages and disadvantages of bilingualism
Bilingual families usually develop a system, either explicitly or subconsciously, for deciding which language to speak. The most common is probably ‘one-person-one-language’ whereby each parent speaks to the children in their native language. This has the obvious advantage that the child picks up the languages from native speakers (I certainly don’t want my children picking up my error-strewn Greek!) and the parents feel comfortable because they are speaking their mother tongue. The language spoken when everybody is together as a family will often depend on the parents’ proficiency in each other’s language. We usually speak English together, as my wife’s English is far better than my Greek and it’s hard to break the habit. The system will usually change when we have guests however as we don’t want them to feel left out. The language siblings speak between themselves will usually be Greek, especially if they are of school age, but it may depend on their activity (they often speak English when doing things they usually do with me, such as playing on the computer).
