Babysitter - Full-time / Part-time

We are looking for a great nanny for 2 children in Arlington. Our boys are fun and energetic. We have a good backyard for playing, especially for water table play on hot summer days. We need help for approximately 1 month Monday through Friday for 8-9 hours a day. We prefer a nanny who does not smoke and who is comfortable with pets, we have one cat.
