My care and feeding schedule goes something like this:
When I'm at home (and not playing), I keep it propped against the sofa safely in a corner, for easy access. I try to keep it away from the table when eating, because as much as I love my marinara, I don't think it would do much for my 'ukulele.
When I am ready to go to bed for the evening, I place it back in the padded gigbag, so the dogs don't accidentally tear it to pieces.
If I am taking it with me on a weekend or for a little roadie, I try and make the fit in the gigbag a bit more snug by adding a couple of hand-towels as neck supports, etc. (Happily, I have one of those uber-padded Orcas gigbags that come with the aNueNue, so I'm pretty confident that nothing bad will happen on a road trip)
I wipe it down with the microfiber cloth at every re-stringing, since that's the only time I can really get at the soundhole, or at the base of the bridge & fretboard.
Other than that, I just try to be sure not to do anything silly, like use it as a cricket bat, or to swat flies.
So far, so good.
