Au pair/demi pair

We are a young family in the bayside/portphilip area (close to the beach/ public transport and the city). Looking for a Demi pair with some availability for extra hours on the weekends if mutually convenient. 2 kids with professional working single mum need house help, home work help and less intensive childcare than babies as the kids are 7 and 9. We are not an up tight house hold as we are busy. Kids are only in my custody 5 days a week and half the school holidays so lots of opportunities for you to have holidays. Preferences for any French speakers.
