Ask HN: How do/would you teach a second language to your child?

For those of us who speak more than one language, how do you handle this scenario ? For example, my daughter was born in the US. She is going to be a "native" English speaker. I am not, neither is my wife. We both speak a different native language even though we have been americans for a while. I would want my daughter to at least speak some of it and be able to converse with her grandparents. How do parents handle this ? I don't want to force anything on my kids.
