French Family looking for helper full time

We are a french family, two adults and a 20 month old baby. we have a cat and a big dog. we are looking for a motivated helper, who is not afraid of animals and who loves children. we are looking for a helper who will take care of our children and our animals with kindness. This is the most important thing. You must be able to cook from time to time, keep the house clean, and clean the car once a week. The day off is saturday but you must be flexible, because we need sometimes in the year (4/5 times) that you take another day instead. We want someone honest, hardworking and who we can trust.
