Babysitting and Nanny Jobs in Mudjimba QLD

I am seeking a part-time baby sitter to look after my 2 younger children (10 yo girl and 8 yo boy), Mondays and Fridays from 7.15am until school starts at 8.35am. We live in Brightwater (Mountain Creek).
The job would involve picking them up after their swimming squad (at Matthew Flinders, Buderim), them taking them to school in Brightwater. They are very active and organised children. I will have their breakfast organised and their school bags packed, ready for the day.

We have a 7 month old baby and a 3 year old.
I work from home mostly and need help with our baby on a Wednesday and both children on either a Tuesday or Friday. This would be an in home job, hopefully with some walks to the playground or beach which is nearby. The baby is breastfed so I will be around to feed him when needed. Hours would be flexible but hoping for approximately 9-4 two days.

A caring responsible Nanny/Babysitter to care for our 4 year old while I work from home/studio.
Any activities you can come up with to fill the day from home. lunches/snacks.
2 days a week.9 am_3pm. days and time flexible.
