Western family looking for helper

We are a family of 5 (two 6 year olds and a 3 year old) looking for a helper to join us. We also have a friendly dog.

We are a busy and fun loving household and would like to find someone friendly, energetic and flexible. 

Main roles would be looking after the house / keeping everything organised, preparing healthy snacks and meals for the children, walking the dog once a day and babysitting in the evening as and when needed.

Ability to prioritise tasks and take initiative would be brilliant but especially experience with young children.

You would have all public holidays and Sundays off. Salary can be discussed.
