As a person who is multilingual, I understand the importance of speaking different languages, and as a person who has children born here in New Zealand, I also understand the importance of retaining those languages within our families—not just for the sake of speaking that language, but for a lot more than that. So my boys went to day care, because I always worked, and slowly what happened—because eight to nine hours they spent in their day care centre—when I used to pick them up they would get the opportunity to spend only two to three hours with us, so, slowly, English became their first language, and our mother tongue became their second language. Then, what happens, with time, in some families I know, is that then English becomes their sole language. They completely forget their own mother tongue. So, as I said before, this is not just for the sake of learning another language, it's a lot more than that, as the Hon Nikki Kaye said. As a scientist myself, I can say this, that this definitely helps with cognitive skills development, and we also know that when children learn a second language, or more languages, from a very young age, they learn them really well. They learn them really well.
