The top 2 interviewees so far are (1) a musician, male, European, seemed great fun and very keen and was lovely, and obviously good with kids; but I suspect may not want to au pair long if something better comes along, and may turn out to be hopeless at the housework, cooking, organising side of things (or may not, he has no references as to this side of the role) and (2) a wannabe-singer, female, English, safe pair of hands, easy to get along with I think, but would definitely not appeal so much to the DCs (and also could leave if something better came along). 2 reminded me a lot of the first full time nanny we shared, though apart from a very short stint has not worked with kids before.
