"She could be asked what her name is, how old she is, what she would like for dinner in spanish and answer, fluently, the answers in spanish.
You could show her colours, and she will tell you them in Spanish... same with foods, animals and family members.
IMHO, that's pretty fluent.
I'm not sure you'd expect much more from a 3.3YO in their native language."
I really would! My DD is 3.1 and she can do all of the above, but a huge amount more as well. She can articulate feelings, use a wide variety of adjectives hold conversations, express her opinions, give me a run down on what she's done during the day, tell me about the stories in her favourite books and films (you could probably put her on mastermind about Tangled and she'd win a prize).
She can also say "Ni hao" which is in the lingo show, but I don't describe her as fluent in chinese
If your DD isn't articulating all the above and more in her native language, and you don't expect her to, then you haven't got a hope of getting into Habs, because that is the sort of thing they will be looking for. Not horses and skiing. Most little ones who are given the opportunity to ride and ski learn how to do so. I take my DD swimming every week and have done since she was 6 months old. She's a good swimmer now. It certainly doesn't make her any cleverer than a child whose never been in a pool though. And no more likely to get into a selective school. Equally, I know lots of bilingual children. On average they're no brighter than anyone other child.
Its not that I don't believe that YOU think your daughter is a genius, but honestly, even with all of your qualifications and explanations about how special she is, you're not describing anything that puts her IQ above a normal, lovely, active 3 year old. And (most) people aren't having a go at you for the hell of it, they're trying to give you a little reality check because you might put all your eggs in one basket and then be horribly disappointed.
