Jane, is looking for a child-carer in London

We have a son and daughter who attend school between 9-3pm. We need a nanny to take the children to school three mornings a week and collect them at 3/330 four afternoons a week. Ideally we would like our nanny to start Monday 3pm and finish Thursday 6pm, and to live with us for three nights a week (mon-weds inclusive).
We are both working parents and so we would well with a nanny that can help around the house with light chores (we also have a cleaner), and most importantly a nanny that is outgoing/ loves sport and adventure (both children love sport), and engage our children in reading and an enjoyment of learning.
Of course we also have school holidays for which we ideally need full time help.
We live in central Islington and we have lots of friends nearby with nannies. Someone who enjoys encouraging lots of social fun/ activities with the group works well with the other nannies and their/ our children.
Thanks.
