Mothers Helper For 4-8 Hours A Week

I'm looking for someone to hang with my 2-year-old son a few hours a week through next fall. Currently he is in preschool M/W from 9-1. I am looking for some extra hours so I can work in my studio (I'm a ceramic artist). My husband works from home, my studio is in the backyard so we are around, just needing a mother's helper so I can get some things done! Very flexible on hours and days. He loves to be outside, is very sweet, and cheerful!
