For DD9 I would use "intuitive" for many reasons. She seems to live her life like she has lived a thousand times before. I would also use sensitive (not always a good thing) if I could pick another word.

For DS3 I would say "organizer" because I have a row of cars on the living room floor organized by color and size. Of course I am not allowed to move them or clean them up, since he organized them so well.
