DH and I have been considering getting a place with his sister, who is single with no children. We have one DS at the moment. We haven't discussed it with her formally but now DH and I are having second thoughts and need to weigh up the pros and cons.
I'm interested to know what other people think - both people who live with their extended family and people who would rather chew off their leg than have Great Aunt Ada shack up in the spare room.
