Nanny Needed - Full-time / Part-time

We are looking for a mother helper and backup nanny for 2 children in Los Angeles. We are ideally looking for someone Friday mornings about 2 hours but open to additional days/hours if more needed. Children are in daycare and would need back up coverage on rare occasions. Tasks include: unloading dishwasher, taking out trash, tidying kids toys. Would also appreciate walking dog if comfortable.
