I asked one of the nursery nurses at my kids nursery if she ever does babysitting. She was really keen.
She knows my kids. They really like her. It would involve playing for an hour then putting them to bed then watching tv or whatever until we got home.
I thought £10 an hour as that is what nannies charge.
She said her rate was £10 per child per hour but as she likes my kids she'd do £15 per hour!!!!
