Babysitter Needed for my Children - Now Hiring

We need a nanny for our son in Somerville. He is 1-year-old and extremely happy and playful. This would be in our home, 3-5 days a week (open for discussion). We do have a cat. Looking for someone kind and patient who is comfortable making him lunch, playing and taking him out to the park and library (both within walking distance), changing diapers, and putting him down for naps.
