While I can’t really speak for the other nations, as it’s not
made explicit, this does happen with Iceland. He just wakes up and
automatically knows he’s different.
With Greece and Egypt, they both refer to Ancient Greece and
Ancient Egypt as their mothers, but I’m still skeptical on whether they were
actually born in the traditional way.
When Iceland is born, he instinctively senses Norway as his
older brother. Maybe that’s what happened with Greece and Egypt too. They woke
up and automatically knew who their mothers were.
