Nanny Needed For My Children

We are looking for a great babysitter/companion (she is 12 so its less babysitting and more keeping company and hanging out) for 1 child in West Cambridge, near Fresh Pond. We are looking for 1 or 2 evenings a week from approximately 7-11 p.m. The specific days can be flexible or standing but we are seeking at least one weekend evening at a minimum. We currently have no pets but may get a dog some time this fall. She is a great, silly, active kid who loves being outside but is also happy to hang on the couch and watch a movie.
