Babysitter Needed for my Children

We need help on Tuesdays and Wednesdays for a few hours each day while our regular nanny is at school. The schedule is flexible, and either mornings or afternoons could work. I'll typically be working from home during this time. My son is 18 months old. We'd love to find someone who enjoys spending time with little ones and has experience with toddlers. We also have a friendly dog, so being comfortable with pets is important.
