I'm looking for a reliable, friendly babysitter to look after my 8-year-old after school for a few hours. The job is for a one-time occasion but could lead to occasional future availability. Responsibilities include supervising homework, preparing a light snack, and ensuring my child is safe and engaged until I return home. Ideally, you have some experience with school-age kids, basic first-aid knowledge, and a calm, patient demeanor. We value punctuality and good communication, and the home is close to public transport. Please mention any certifications and your availability for this week.
