I think it is a great idea to teach children second languages, they do tend to pick it up quickly. My partner is from Turkey, but his mother tongue is Kurdish and we live here in Turkey. So when we have children they will need to learn three languages, English, Kurdish and Turkish. If we continue to live in Turkey, they will be going to a Turkish school, and if we later decide to move back to the UK, they wll need to be fluent in English. I think if my children are bilingual they will be more determined and work harder. One of my friends is Fnnish and her husband is Turkish, they have a one year old and they speak to her in Finnish, Turkish and English, they want her to learn all three languages.
