He's six years old, speaks three languages fluently (putting me to shame!), and is enrolled in school at the moment. Even though I work remote, I do it from a home base, and use that as a jumping off point when we travel during school holidays, summer, etc.
What other education a kid needs than to have parents who can stay with them all day and teach how to work from anywhere in the world?
I think the more important thing is how does the kid socialize?
