I am looking for a reliable and experienced babysitter to care for my two children over the weekend. They are aged 4 and 7, and I need someone who can engage them with fun activities, prepare simple meals, and ensure their safety while I am away. Ideally, the sitter should have previous childcare experience and be comfortable with light housekeeping related to the kids. The weekends are flexible, but I would prefer someone available Saturday afternoon through Sunday evening.
