Full Time Nanny For Infant (and Sometimes A Four Year Old)

We are looking for an experienced nanny to primarily care for our infant son. He will be around 12 weeks old. Our4-year-old son also starts kindergarten in the fall and will need to be picked up and supervised for approximately an hour and a half daily starting in August; he will stay in all day preschool until then. He likes to go for walks to the neighborhood playground and library, play with trucks, and build legos. We value experience, safety, simplicity, and reliability. We can offer guaranteed hours, consistency, and good communication. We don't have any pets. We use an online payroll service, offer quarterly performance bonuses, and would plan for at least two years of employment.
