Afternoon Nanny sought in NW3

A full time, single working mother to two children - a girl aged 9 and boy 5 - who are both at different schools in the West Hampstead area, is seeking an afternoon Nanny to cover weekdays from 3pm-7pm (or 8pm or later if she has a business dinner).  She is Russian by birth but speaks very good English (as do the children).  The family home is in Hampstead and mum commutes into Watford Junction during the week.  Cleaner employed.
