But your daughter has parents competent to guide her with her Russian and English.

Her parents understand spoken American English and can read it, but as for guiding her or correcting her syntax/grammar, they're far more limited. They also live in a very French area, not in Montreal. But I doubt they would stop her from reading a book in English if she wished to, they just won't push her to read in English for now.

But I extrapolate. Aside from an expressed preference for French pre-school literature over what they've seen available in English, I don't really know their motivations. Both teach young kids and don't read English books in translation (not even when it's the translation they offer in class), so they have tons of books in English for older kids at home (from 6 to 12, roughly). Eventually she'll get a much larger access to English children books than most kids from a francophone background do (for most, it's none at all).

It's already much better than us. We started reading in English only around 12 (in school, with Christie's Murder on the Orient Express) and there's never been a single book in English at home as we grew up. I wish I would have started earlier, but OTOH I suspect the fact I read so many French classics and contemporary literature as a teenager owes much to the fact I didn't read regularly in English before I was about 16.

We're more or less the first generation for which learning English was somewhat encouraged (less so than now, for political reasons) and part of the public school curriculum. In my parents' youth, the Catholic Church still held control of public schools and discouraged learning English. One more mean to shield us from the so-called "evils" of protestantism.
