Babysitter Needed for my Children - Now Hiring

I'm looking for a great nanny for my children Mondays-Wednesdays and sometimes Thursdays, 9-5 or 8:30-5:30. My 3-year-old daughter will be in school 9-3, so most care will be for my nearly 1-year-old son. They are both great, fun, loving kids. We have a backyard and a playroom and we would love for someone to take my son out for activities (library, park) during the day. Some light tidying up, mostly of the children's spaces, would be great. We do have dogs- no dog care would be expected but we want someone who is comfortable with pets.
