We want to think ahead and decide what the ground rules/living arrangements are so that we dont all drive each other nuts and nothing gets personal. MIL is not in great health and a bit needy - I am worried that I will be on call 24/7.....has anyone done this or know any family who have done it well -- happy to hear the horror stories. Also wrt finance the plan was that she sells her house, builds an annex on ours and what is left when she dies is split between the 3 siblings - does thats seem fair? Other two siblings live far away so will be no practical help on a day to day basis.
