I'm getting ready for a handover from our current au pair to our next one early next year. There will be a week when they are both working together to hand over. Can anyone tell me how I should work the bedrooms? Our au pair has a bedroom (of course) and the new au pair will get this room. But where I'm lost is should the new one go in the spare room for the handover week or the old one in the spare room and then move when the old one goes (iyswim)? I can see arguments for both arrangements but would be interested to see what people usually do.
