Haha, I've been there. When DD had just turned six we memorably spent An Entire Day playing space. We played with her toy astronauts and rocket, looked through her space books, watched documentaries, when I tried to get us making tinfoil bracelets she made an entire anatomically-correct tinfoil solar system and turned my bracelets into distant spiral galaxies … you get the idea. When I'd finally had enough I went to hide in the bathroom too! And she slipped a note under the door saying "There are no toilets in space".
I loled so much!
And that note (now framed and hung in the bathroom!) is what finally made us decide to have her tested. But my tip is to outsource - I've signed her up to heaps of clubs and activities so she can share the joy with other enthusiasts. I have to say I mostly do listen because she has some very interesting hot topics but even so I never thought I'd learn so much about particle physics!
So fingers crossed there's a Crimea enthusiasts group near you
