Seeking full-time nanny in Bellevue Hill

We currently have 2 girls (4, and almost 2) and a 3rd girl on the way (due end of November). We are looking for a full-time nanny that has experience with newborns and toddlers and flexibility with their schedule. On a regular basis, we are looking for 8-9 hours of help per day from Monday through Friday. We will have a separate live-in nanny to help take care of the newborn for the first 2-3 months, but after that we would want our nanny to help with the baby as well. Our 4 year old will be in school most of the day. Thank you!
