Almost exactly 40 years after I moved to Sweden, my kids are going to move there to live and study for a few years and who knows maybe they decide to stay there instead of moving back to France or even the US.
I have started teaching them Swedish, together with Babel for self-learning, found this book a great start for beginner level.
It is fun spending several hours per day on Signal app to have virtual classes and go over the material, pronunciation, basic grammar among other things.
One really amazing thing is that both of them have problem with the "R" in Swedish, they both pronounce it like the French, even thought they have no problem with it in English. I guess their bilingual mindset is switching to French mode when trying to learn a new language.
