Bilingual kids in Polish schools [30]
I agree with the assessment that those bilingual children of whom I spoke were indeed exposed nearly equally to both source and target language before attending school.
In my case, I was raised partially by a German "nanny" who spoke nothing but her native tongue to me prior even to kindergarden, while my folks spoke only English to me and I never studied German formally until I was sixteen.
Does that make me bilingual? Yes, according to the narrow confines of the above definition. On the other hand, my nanny stopped speaking to me in German altogether by the time I was only eight, so there were nearly nine or so years before I actually learned the language as a young adult, having most of my adolescence to catch up, so to speak:-)
