Hi all, I could use some advice. I need someone to stay overnight from 9pm till 7am with my children who are 11, 15 and 17. They are pretty self sufficient, only the younger one needs to be reminded to go to bed & they will have had dinner. I just feel safer when there is another adult in the house. My former nanny is happy to do this as she lives close by but when I asked her what would be fair pay, she said it was up to me. As I haven't used a sitter in a while, I am not sure what would be fair. Any recommendations? By the way, we live in London so I expect to pay more than outside London.
