To be honest, there was nothing I didn’t already know. I think in Europe we’re less questioning the bilingualism or multilingualism than in US or Canada. I’ve studied bilingualism and know a lot about this. Being multilingual myself and raising multilingual children, I kind of have done my own research on this topic and my results are the same as mentioned in this interview. I went to an international school, spoke already Italian and German by the age of 2 and added French when I was 6, English when I was 11. Other languages followed and I can only say that you can learn languages your whole life. It depends on your motivation and dedication if you will become fluent. Also the phonological part is still possible, if you learned ad imparented language at an earlier stage. There are studies who point out that if an English child is exposed to Chinese phonetics very early, he can become fluent in Chinese also later.
