Childcare Needed - Full-time / Part-time

We need a nanny to take care of our 1. 5-year-old son on a weekly basis every Friday. We would occasionally be interested in evening or weekend hours but primarily need someone each Friday. He is an absolute joy to be around, loves going to the local library and museums, loves reading, and is learning new words every week. He takes one nap a day generally between 1-3 p.m. and has a general schedule for food and sleep. We would prefer someone who could help out with light housekeeping (washing dishes, vacuuming when needed etc.).
