Thanks for sharing! Concerning logistics when travelling I can also share my experience.

I travel on a Dutch passport and my children, while also having Dutch citizenship, travel on German passports because that is where we live and where my wife is from. They also use my wife’s German last name. Therefore, when travelling, my kids and I have different names and nationalities. For some reason nobody ever questioned any of that. I keep a copy of the birth certificate just in case though.
