Nanny Needed For My Children - Full-time / Part-time

We are looking for a great babysitter for 1 child in Melbourne. We would prefer someone who could help out with light housekeeping. We would prefer a babysitter who has their own car. I'm currently expecting with a due date of the 16th and needing someone who can watch my 2-year-old girl while I'm in labor and here and there when I'm postpartum. We may modify to also watch the newborn just depending on how my rest is going. If you don't want to watch both that's okay , not a deal breaker. We're most interested in someone who has alot of availability as you never know when you'll go into labor.
