Bilingual people

I'm interested in this topic and want to know more about bilingual people. Do you know anybody who speaks 2 languages by birth? May be you are a bilingual person yourself, if so, tell me, in what language do you usually think and speak? I know that there are people who were born in a family with parents belonging to different cultures. So, these children start speaking 2 languages automatically. I wish my future child could speak both Russian and English and I know some women in Russia who know English perfect and they developed a special education programme to bring up their children as bilingual persons. But isn't it a bit risky, in case if your child ultimately mixes 2 languages and starts speaking his/her own variant or stops speaking at all?
In other cases, people who leave their motherland as little children can also start speaking the 2nd language fluently, as native speakers. My friend left Russia for Canada when she was about 9-10 years old. But she comes back for every summer holidays. So She speaks engl.(delted) perfectly and she still speaks rus. but when she arrives she has an awful english accent and all the intonations are wrong in russian,(suppose I sound the same (deleted) when I speak english with russian intonation) so we always laugh at her) But she adapts in a few weeks and her speech becomes quite OK.

But isn't it a bit risky, in case if your child finally eventually mixes the 2 languages and starts speraking speaking his/her own variant or stops speaking at all?

In other cases, people who leave their motherland being as little children can also start speaking the 2nd language fluently, as native speakers. My friend left Russia for Canada when she was about 9-10 years old, but she comes back for every summer holidays. So She speaks engl. in English perfectly and she still speaks rus. Russian, but when she arrives she has an awful English accent, and all the intonations are wrong in Russian. (I suppose I sound the same just as ridiculous when I speak English with Russian intonations.) so We always laugh at her, but she adapts in a few weeks and her speech becomes quite OK good.
