Sabine, cherche une nounou à domicile - 75006 Paris 6ème arrondissement

We are looking for a full-time nanny to care for our 3 children (2 school-aged girls and a newborn boy) in Paris (6th).
The nanny will be caring for our baby during the day (feeding him, taking him to the playground, playing with him) and picking up the girls from school or after-school activities (walking distance) around 4.30 pm (12.00 on Wednesdays) and will supervise the homework.
I work from home part of the time but am used to staying out of the way.
We are thinking we would like our nanny to start part-time in October (3.00-7.00 pm) and go full-time at the beginning of November. Full-time is:
Monday: 2.00-7.00 pm
Tuesday: 9.00 am-7.00 pm
Wednesday: 9.15 am-7.30pm
Thursday: 9.00 am-8.15 pm
Friday: 9.00 am-6.00 pm

This is a total of 45.5 hours, but with 14 hours of "presence responsable", which brings the work contract to 41 hours.
Thanks
