Hello all - first time I've ever asked a question on mumsnet. Our first au pair started this week, she seems nice (19 from Holland) and hasn't done anything yet to cause concern, however I was hoping to get some reassurance and a quick answer to something. Firstly, it seems so weird and unsettling leaving our children with a total stranger who we have no reason to either trust or mistrust. Initially the idea of an au pair seemed so convenient but now perhaps reality has hit home. How long have others found it takes before you are comfortable with your au pair and what steps should we be taking now to ensure the first few weeks are as smooth as possible? Also, while we have given her a handbook (which we got from mumsnet), we haven't given a contract, everything seems a bit informal from an employment perspective, even though the handbook very clearly lays out responsibilities and expected hours of work. Should we have something more official in place? Hoping for some experienced words of mumsnet wisdom. Thanks all.
