Babysitter Needed for my Children

We're looking for a part-time nanny for our 16-month-old son. He is very active and loves to be outside. An ideal day would include outside activities, walks to the park, puzzles inside, a nap, and lots of snackies. We have two cats who will also be around. Hours may vary from week to week, with at least a week's notice. I am still waiting for my schedule for the semester - days will likely be shorter than listed in the posting.
