We are a fun and flexible family looking for a nanny to work with our 2 kids. 1 girl who is 4, 1 boy who is 19 months. The job would include school runs, taking the little boy to playgroup, playing games, and swimming. Household duties would be children's laundry, tidying kids toys + little general household work. After school, homework and bath but no meal preparation. We like to have fun and want our kids to enjoy life with small doses of routine. My husband and i work full time in London in non-office type jobs. The hours would be 7:30-5 M,W, F
and 7:00-5 Tues + Thurs. Salary will be ?275/wk net.
The position will only be full time until Sept, and then will turn to part time as the little one will be in nursery. If you have a license and car, that would be a plus salary wise, but not essential. References required. Please e-mail me your CV
