Babysitter for 2 children, London, Merton

We need a live-in nanny to care for one child and one infant starting from January 2020. The mother will be on maternity leave until early May to care for the infant. The child will start nursery from January for 2-3 days per week to gradually increase to full time. The nanny is to be responsible for the children and housekeeping/cleaning related to them. General housekeeping is done by a cleaning lady. Nanny will have a separate large bedroom and ensuite bathroom on top floor.
