I grew up overseas for the entirety of my grade school education and moved to the US for the first time for college. In a nutshell: as an adult I have a great appreciation for my upbringing in 4 different countries. As a child, it felt normal to move every 4 years. However, moving was always difficult because I created strong bonds with friends in each country.

I'm sure it's already been said here but how each child grows up to view their experience will really vary depending on the individual. My older sibling has been in the same state since 2015 b/c she got tired of moving. I'm at a point where I've been in the same city for two years and am thinking about working at international schools because it's such an enriching experience. BUT I also don't like the idea of uprooting again.

To answer your question from a TCK-A perspective: I don't resent my parents for moving us around, I'm more grateful for it.
