Family looking for helper

We are an international family with three children looking for a helper to support us with duties around the house such as general cleaning, laundry, and child care. There is another helper and a driver so this will be a team effort. The priority of the role will be looking after our younger son who has some support needs and goes to speech therapy and occupational therapy regularly. We would expect the new addition to the family to go along to these sessions to learn the techniques to best work with him. All our children are very active with sporting activities, but the older girls do not need much assistance.
