I think climate control will be your big issue if you can work things out with the building department. Most of the other things aren't too difficult.
with wood isn't uncommon. Cooking on some sort of wood cooking stove is doable, or you could use something electric--I'd recommend an induction burner (energy efficient--my breakfast takes 0.08 kwh to cook in the morning). You can get a chest freezer & swap the thermostat, creating a chest fridge for energy efficiency (just be sure to catch the drain water from condensation inside the fridge). Water
will be a challenge without propane or lots of electric power, but there's potential to do solar water heating. You'd want to learn how to burn wood cleanly, though, and make sure your son isn't sensitive to the wood smoke.
Back to climate control--my yurt gets really hot in the summer (10+ deg hotter than outside temp), and on cold days it basically follows the outside temp unless I heat 24/7. But my platform is drafty & I don't have much
. Both those things will be changing shortly--I don't know how comfortable I will be this winter... If you can figure out how to manage the temps well, you should also be able to manage the dew point (humidity) and avoid condensation leading to mold.
To be honest, I wouldn't recommend a yurt for someone that can't thermoregulate. A more traditional-style wood stick/framing would likely work better for you (say, have someone build the shell and you do all the interior or such). There's a fair bit of nuance to making yurts livable, and I don't think it will be a turn-key type of situation. I think it's possible, but expect a bit of trial & error if you do try. Other's experience may be different.
