Compression of the spine, eh?
Does that mean if you lost a lot of weight (say 100 lbs) you'd actually grow taller, because of less weight compressing?
(I am an inch and a half away from 6 ft and I know it's dumb but I want that inch so bad arg)

I'm literally just under 6ft, not that 5'11" crap, I mean I am that fraction under 6ft. So, yes, I know your pain.

That doesn't make sense. Extended bed rest is physiologically very similar to zero g - that is how they do studies on the effects of long duration flights. You need g-force to stress your bones and prevent decalcification, but even in high g fields there is very little stress on your skeleton during bed rest. Nope. Sleeping quarters are in the low g-sections near the axis.
A full g equivalent is not necessary for long durations - a small fraction should be sufficient to keep your bones healthy and strong. Muscles may be less developed - but that is easily addressed with exercise. The minimum G force needed for long term health is not known, but a half g would seem reasonably safe, and hopefully 1/3rd g too if we are ever to do more than visit Mars. Recent research suggests that it may only be necessary to spend relatively short periods of time exercising in artificial high g on a regular basis to maintain health in zero or very low g environments. So it should be the gym, not the bedrooms in the high g section.
But ... that all applies to healthy adult astronauts ... not a growing child. HannerDad would have been remiss to allow a growing girl to grow in less than a constant, stable 1 g environment.

Get an inversion table, or make some friends in the BDSM community who have a rack. You can gain that extra height ... but it will only be temporary.
Boomslang:
I know there have been studies of invertebrates in freefall- have they done any experiments with mammals in space, to view the results on the offspring? I haven't heard of any, and that'd be quite instructive, I'd think.
