Need occasional babysitter for after-school pickups in Saturday

I'm looking for a reliable babysitter to help on an as-needed basis for occasional after-school pickups and short evening shifts. We have a 7-year-old who enjoys reading and outdoor play. Ideal candidate is patient, sporty, and comfortable with light meal prep and homework help. Duties would include picking up from school, supervising until I return, preparing snacks, and ensuring homework is started. We’d prefer someone with prior experience with children of this age, basic first aid knowledge, and references. Availability on weekends or weekday evenings is a plus. We can discuss a flexible schedule and rate to fit both parties.
