How do you take up your potential au pair's references?
Our first au pair was German and I persuaded dBIL (who lives in switzerland) to ring up and check her references.
I'm trying to recruit again at the moment and have a potential candidate who is french - I speak french but have never tried doing it over the phone. I prefer to read/write french but are written references (email or letter?) even easier to fake than a phone call?
What do you do (or are you all fluent multi-linguists?)
