If it's a walk-out basement, can you walk her out and up on the outside, without stairs, so that she can come into the house upstairs, then crate her there, where the people are? E.g., if you are watching TV upstairs at night, have her in a crate next to the couch and she'll feel included in the pack and relax.
Alternatively, is there some big, strong guy in your home who could carry her upstairs for you to keep her in the crate up where you are, without her having to take stairs?
If not, can you plug in a TV or computer down in the basement, or take a Kindle, and a cozy chair and just sit and hang out there with her, so that some of her time interacting with you is just sitting-and-chillin'-with-mama time? When I work at my computer, I've nearly always got a dog under my desk (sometimes with a head on my foot)--I'm working, but they get to be close and relax. Could you do something like that with your girl, even if you are busy doing other things?
