Experienced Nanny For Newborn (6 Weeks), Part-Time

Hello
My husband and I have recently given birth to our first baby (6 weeks ago), we are experiencing the big learning curve that comes with babies and unfortunately we don't have family in Perth and are finding the need for additional support and help with our baby.
I am ideally after support for a few hours a day for 3-4 days a week (I am flexible on days), preferably afternoons.
I will be home during this time, and working from home. I would like help with bottle feeds (when I'm not breastfeeding), settling baby, activity time, nappy changes.
We would like a nanny experienced with newborns and that has the relevant checks and references.
Thank you
