My 4 year old DS is going to be looked after by another family's nanny for 3 days over the holidays, while she's looking after the other family's children (they're all friends, play really well together and the other family are happy for this to happen).
Now I asked her how much she charges and she said that she charges £9 per hour but is happy to take less as she's looking after the others anyway. I asked if she charges £9 per child and she said 'per family'.
What is usual in this situation?? I have no experience at all.
