I don’t think it’s ever too early to start talking, in however many languages. I remember being at school with children who could speak 4 or 5 languages at a very early age.
As someone who is mixed race, but not bilingual, I very much wish I could speak two languages.
My mother is british and my father is HK chinese. My mother only speaks english and my dad speaks both english and cantonese.
I was only ever spoken to in English, and though I lived in Hong Kong for 7 years, I never picked up Cantonese. I feel somewhat ashamed that I can’t speak the language, and it is embarrassing when a chinese person approaches me, assuming I can speak cantonese.
I am now making the effort to learn the language (at the grand old age of 21) – As I don’t live in HK anymore I’m guessing it’ll take a while, and I really wish I’d been exposed to it more as a child.
