Sending calming hugs your way.... It's gonna be crazy nutz for a while....most of all try to keep your sense of humor....TALK to each other about "stuff" so that bad/hurt feelings don't fester. Assuming that something life altering already happened that caused the move in....so there is enough stress right there. Gotta take an "all of us" against the world attitude if you can. STAY AWAY from negative input / people....they are "vexations to the spirit".
I wish you all very very well....and hope that this turns out to be a "good" thing in the end.
Wow......How far we've come from "generations" all living together in tiny cabins !!!!!! But they obviously survived !!
