WOW!!! that is an absolutely beautiful specimen, jenn!!!!
turning it regularly, as you do, is the best thing to do...really helps it to be a well-balanced plant
. and it DOES keep it from growing
hopefully your mil has a window that faces the same direction as yours and it's got the same amount of light shining in.
if not, find as good a spot as you can and use a grow light for a couple of weeks to help transition the jade with as little stress as you can.
start off with the light set on a timer so that it will go on at dawn and off at dusk. leave it like that for at least 5 days so the plant
can get used to the air quality and moisture conditions at mil's.
then start cutting back on the time the light is on...shorten the time by 2 hours a day and take it down every 2 days until it's not on at all. you shouldn't lose one leaf.
