Babysitter Needed for my Children

We are looking for a regular part time babysitter for our child who is turning 4 in September -- one to two weeknights from 5:30-7:30 (after daycare pick up) and one weekend afternoon 4-7 p.m. (Sunday preferred). We're looking for someone patient and creative who can do structured activities with our son in the home or at nearby parks, in addition to helping with meals on those days. He loves numbers, building "cities," riding his balance bike, and reading. We are both working parents who will generally be around during babysitting hours and would love to have a child-centered caregiver in the home who can keep our kid engaged.
