Seeking occasional child care for date nights and weekends

I’m looking for a reliable babysitter for occasional care for my two kids aged 4 and 7. This would include after-school pick-ups, dinner, bedtime routine, and light homework help on days when I have appointments or events. I prefer a calm, responsible caregiver who is comfortable with kids and has first aid training. Availability would be a few evenings per month and some weekend slots. Please include references, DBS/DBS equivalent checks, and flexibility with last-minute requests when possible. I’m located in [City], UK, and would like someone who can start within the next couple of weeks. A friendly, warm rapport with the children is important, and the role may evolve into regular occasional care if we’re a good fit.
