Make sure you have the support network that meets your expectations. We moved home once for that same reason and ended up being lonely with very little extra help compared to the social system abroad. Family may or may not be a blessing with your kid and it caused a rift because they were so hands off.
Privacy and fun family life. We are a big family & lived throughout the US and abroad. Coming from big expectation families it’s nice to do our own thing.
Enjoy, it could be worse. Unless you are planning to leave soon just out of education stress, teach them to read and enjoy books when they are home. I homeschooled my kids for 5-10 years, they also have been to American and Dutch schools. Now with 3 in universities, they only talk fondly about their time homeschooling and think it prepped them for real life and university the best. I would never encourage homeschooling or relaxed education but I’m surprised the kids did their best growing/learning/reading/exploration then.
My daughter is still close with her American friends and they are in school and sports activities for 12+ hours a day. She sleeps and studies in class and is burning out for a chance to go to a sub-par Florida university. My kid in contrast is studying at a university a few hours, studying at home, riding her bike, has a part-time job and loads of great friends. This is a dream life in comparison.
One country we one wayed it. Next country, we sussed it out for 2 decades and still were surprised by how different life was tourist vs resident. I know a lot more than students in my language classes but that’s the only difference.
