Babysitter wanted for childcare in Whitby

Single mom of two great girls, 15 and 7, plus our small dog. My 15-year-old is fairly independent and often helps out with her sister, but I like having an adult around for evenings or overnights when my work schedule keeps me out longer than usual. Looking for someone reliable and warm whos comfortable with a mix of light supervision and being a steady presence in the house. Needs to be available for occasional overnights if needed.
