we had 4 au pairs - two brilliant, two awful. 3 german, 1 Finn
Our first aupair - a Berliner, was lovely with the kids and the family but hated housework. SHe was, however, intelligent and sociable and had good humour, and so fitted in well. She came from a wealthy family and felt hard done by on the money she was paid (slightly above normal).
Aupair No 2, from southern Germany, was only here for 8 weeks.....what a long 8 weeks they were! SHe was a vegetarian, and very lazy. Again good with the kids but slovenly. Would dissappear into her room never to be seen again and tasks were done in the longest time - 3 hours to iron 6 shirts. SHe ate us out of house and home, and had no clue - she would make a large bowl (mixing bowl size) of pasta and then leave it out for 2 days until it grew a fir of mould before throwing it out and starting again. Her personal hygiene also left a lot to be desired, and we had to throw away her mattress after she left - i shudder to think what had gone on in her bedroom that her mattress and cover were destroyed. she managed to block our toilet, and a toilet where we went on holiday, I do not know how.
Aupair no 3 was finnish and my favourite. A sweet natured, hard working, delightful young woman who really fitted in with our family and I was so sad when she left. We keep in touch, she still refes to my DD as her little sister.
Aupair No 4 - NIGHTMARE! southern German with a major attitude, barely spoke English and admitted that most of our correspondence was done by her neighbour. She was an only child whose parents were on the verge of a divorce, and she was running away from a bad situation. SHe would have massive rows with her parents on skype, and then shut herself away for the day. She didnt like the kids (and they hated her) and would sulk if asked to do any housework. Had no clue about how to clean anything - did the loo with Fairy liquid (despite being shown otherwise) and then hooked up with another German chap on MSN chat - he was unemployed and would ping her all day and night - she would drop whatever she was doing and go talk to him for a couple of hours. One day she left the iron on in another room, for 2 hours. She decided to go home to meet the boy after 6 weeks. We gave up on aupairs after that.
My advice:
o Speak to them on skype, do not rely on written emails.
o Look around!
o Try and choose a culture similar to your own. The aupairs I have got on with best have been Scandinavian (my Finn plus her lovely swedish friends) and German from a large city. The other two germans were rural southerners, and we had completely different outlooks.
o Choose someone with intellect and educational aspirations and potential similar to your own.
o be very clear what you expect, and when they say they can cook, dont expect masterchef. You will need to show them how to clean, do not expect them to know which products to use in which situation.
o Remember they are teens, away from home, with all the personal dramas associated with teenagers. Boyfriends, fall outs with mates, complaining that they have no money (because bank of mum and dad not on hand to bail them out)...be gentle with them.
Our lives were enriched by two of ours, and we have many tails to tell about the other two.
