Nanny Needed

We are looking for a part-time babysitter starting in September for our 4-year-old son. We live in Morningside Heights/UWS. We need someone Monday-Friday from approximately 1-6 p.m. (though starting in October, most Tuesdays and Wednesdays it can only be 2:45-6 p.m. if that is preferable). It will involve picking him up from preschool (located a few blocks from our home) and taking him to activities/playdates/parks or playing at home. Might involve some preparation of light snacks and food. We are seeking someone who is reliable, energetic, fun-loving and responsible. Bonus if you love sports, music, and Legos (his current passions). Thanks!
