Nanny for twinfants in Newtown

We are an Australian / Norwegian family, consisting of a mum, a dad, and two 5 month old baby boys. The dad works in renewable energies and mum is a university lecturer at the Uni of Sydney, and the twinfants have yet to elect a career. Unsure what else to say, but we're a cheery household, the boys have thankfully turned out to be very playful, happy little creatures - honestly, they rarely get upset! Our house has a large living room area with a playmat where the boys spend much of their time. We're also near a couple of the Camperdown / Newtown parks, and the boys love to go for a stroller ride, often wearing their cool sunnies.
