After-school babysitting and homework help for two kids

I’m looking for a reliable babysitter to pick up my two children from the local primary school, supervise until I get home, and help with their homework. The job would be 3–4 days a week during term time, roughly from 3:30 pm to 6:00 pm. We’d also appreciate light snack preparation and some outdoor play if the weather is nice. Comfortable with school routines, first aid basics, and engaging activities. Please highlight any relevant experience with children aged 6 and 8, and confirm you’re available on weekdays. Location is in [City/Suburb], UK.
