There are great advantages of having an Au pair. In the early days i would never have been able to work P-Time, I had one in child in reception, one at nursery school and two at a creche on the days that i worked. It was still choatic but more managable, with ironing up to date, getting the kids out the door on time, and some one to pick up from school, seemed to work..
( i'm almost talking myself into another Au pair)
However, I have just replaced my third hoover in 4 years and Au- pairs room is a disgrace, stains on the carpet, ring marks, cracks on most of the furniture. At times i felt like social secretary to Au pairs, taking/passing on messages ect.
Our current Au pair is 28 going on 48 has on the whole been very good: makes very few demands on us, is sensible and kind with the kids, and totally reliable, is considerate with the phone and internet. But she has terrible habits, I have caught her drinking directly from the milk bottle and putting it back in the fridge, picking at food with fingers that i have just pulled out the oven, she can't get out of the habit of saying, Geeesus christ and shit, never says please or thank you, her spoken English has not improved in 12 months.
Over time, some things I have learned to accept ( not disgusting habits)
So I am going to have an Au pair break, and see how things go. I have already started getting the kids to help more - never too young to start.
