Nanny Needed For My Children

We are looking for a part time nanny for our almost 2-year-old son. Preferably someone who can be with him at home during the day, 2+/- days a week, and an occasional evening or weekend, but schedule is very flexible. He is an energetic kid who loves to be outside. We have one cat who spends most of his time outdoors. We would like someone who is attentive and likes to have fun, someone who doesn't take themselves too seriously :)
