Do be mindful of the kid though. One of my wife's coworkers wanted to teach their kid multiple languages, I think the final count was 4 total (they wanted both the parent's native tongues, German which is where they were going to live after their visas expired in the US and of course English), while living in the US and it just made the kid confused and angry. Granted that's way more than just doing two but it could still back fire with the kid if it's too much.
