Looking for weekend/holiday childcare for two kids

I’m looking for a responsible and caring babysitter to help with weekend and school holiday coverage for my two children, aged 5 and 8. The role includes supervising playtime, preparing simple meals, helping with bedtime routines, and ensuring safety at all times. We’d prefer someone who is comfortable with light homework help and outdoor activities in good weather. Availability on Saturdays and Sundays, plus occasional midweek during holidays, is ideal. A brief background check and references would be appreciated. We’re located in [city], UK, and would prefer a candidate who is comfortable with a flexible schedule and a friendly, calm approach.
