Childcare Needed

My kids are very active and love to play. We currently homeschool, so our sitter may need to oversee assignments and keep them on task (no lesson planning or instruction required). I am looking for part-time care, mostly for someone to play and engage with the kids. This will allow me time to get things done like errands and grocery shopping solo. They both participate in competitive sports and love being outside. Our ideal sitter would be someone who loves to play and share their imagination with our kids. As well as maintain a kind, but firm, attitude with them.
