Need occasional babysitting for two children aged 4 and 6

I'm looking for a reliable babysitter for occasional, short-term cover during weekday evenings and weekend mornings. We have two kids, ages 4 and 6, who are sociable and well-behaved. The role would include supervising play, preparing simple snacks, light bedtime routines, and getting them ready for bed on weekdays when needed. We value someone who is patient, energetic, and has experience with young children. A valid DBS check or equivalent is preferred, along with references. Please indicate available times, any certifications, and your hourly rate. We’re located in [City], UK, and ideally want late afternoon or early evening slots, with some weekend flexibility.
