We need an au pair for our two little children, a boy 8 and a girl 5. This would be part time from 1.15pm until 6.15pm four days a week (Mon to Thurs). 20 hours per week in total.
You would pick up the girl from school at 1.15pm (2min walk from the house) and then collect the boy at 2.20 (also 2 mins walk from the house). The kids are very easy to look after and the only other tasks are making them lunch/dinner and helping them with their homework (20mins usually). Everything else is just looking after them and playing with them.
There is generally a few days off per month when their grandparents are in town. You would of course get paid for these off days. There is also some optional cleaning and baby sitting hours available at various times throughout the month.
