Babysitter Needed for my Children

My son is a very active and clever 7-year-old boy. He enjoys riding his bike, swimming, playing with our dog, building legos, and generally being goofy. He is mostly well-behaved but he likes to mix things up, mainly for his own amusement. He attends 2nd grade at a local Catholic school and runs on the cross country/track teams. He is welcoming and easygoing with people who engage him with kindness and curiosity.
