Nanny Needed For My Children - Now Hiring

We are looking for a great babysitter for 1 child in Chevy Chase. My daughter has ADHD, so someone who is familiar with children with learning difficulties is a plus. She is 12 and is in her pre-teen stage so if you can deal with girls in that stage of life that is also a HUGE plus. We would prefer someone who could help out with picking her up from school 3 days a week as well as homework help. We would prefer a babysitter who has their own car, who does not smoke, who is comfortable with pets and who is CPR certified. We do not have a dog yet but plan on getting on in a few months.
