My wife and I are making an emphatic and deliberate effort to raise our 2 boys trilingual. And so, far we're winning at it! We are doing this for the grandparents, and to give our kids the superpower of multilingualism.
Our kids speak fluently Spanish, English, and Polish. Fingers crossed they'll remain like that.
We live in New York City, so English is the dominant language. We gotta be diligent! We are starting to see how English, being the common language in society, pushes our kids toward speaking English. It's the "cool" language their friends speak.
Fortunately, there's a lot of Polish and Spanish around. Also, it's normal in NYC for families to be like ours. I am grateful for having this environment.
