Hello,
I recently have changed my childcare option to Au-pair with the main thought of having someone living at home to help. I had one au-pair before but she was there for only one month as i had to change her due to her hour restrictions. So this time around, I have got a new au-pair who seems nice with my daughter.
But this is her first time as an aupair. So she clearly has no idea on what to expect or what to do basically. For example, she is sharing all toiletries without even asking permission from me. She cooks well but cleanliness is nil even after telling her many times that my daughter is very prone to infections if things are not clean. As a full time working single parent, I find it very hard to instruct every single thing. Am i worrying much as its just her first week. Should i give her some more time to adjust?
Also, I pay her £150 per week and on top if she works extra works, agreement is to pay her more per hour. Agency contract said, she will eat with the family. So when we went shopping, i asked to buy food items that she would like. I heard her saying aah free food !!. But not sure what the limit should be !!! I'm stuck here. Having googled, i found that i need to pay extra £30 to £40 per week just for food on top of pocket money excluding milk, butter, other food items etc. Is this the norm?
Can someone please share their thoughts on how you handle this situation? How much do you pay for food on top what you buy in the weekly grocery? Or should i just say that her grocery limit is £30 and she can buy anything she wants in that? Please help 

Thanks.
