Well after 3 to 5 years, you certainly have settled in your new country (doctors, food, friends, I mean you created a life). Probably you feel the gap between the EU and the US lifewise.

but life is changing and tbh you never know.

Getting a child, having him/her seeing the grand parents or cousins

Havin parents getting old or sick

Havin a career opp

Havin a F-word pandemic

those are example of things that might make you do a move.

So cry BUT enjoy because you never know what will happen. cheers

The rule of thumb is that the parent speaks with the kid the language of its origin. and at school the local one. so I would say skip the english or do as you wish but be consistent

Focus on language. they will make friends esp if it is early. you may want to connect to other expat as a relief
