Part-time and casual babysitter

We are looking for someone to join our family as a part-time nanny to assist with after school pick ups from school / daycare for our two children. We also hope to utilise the same person for occasional babysitting on Friday / Saturday nights when we have family / social / work events. The regular pick up would ideally be on Tuesday afternoon, with the back up option of Mondays. Occasional Thursdays would also be helpful. Pick up is of our eldest ftom school then our youngest from daycare - both walking distance from our home. We have two little girls, our eldest is 6 years old and our youngest is 3. Both children enjoy imaginative play, dancing and singing, playing outside, exploring, craft activities and helping around the house. Both parents work in the CBD when in the office, and also work from home on occasion.
