Looking for weekend and school holiday babysitting support

I'm seeking a friendly and responsible babysitter to help with my two kids on weekends and during school holidays. We need someone who can supervise, prepare simple meals, assist with homework, and plan engaging activities. The role may also include light household tasks related to the children (keeping toy areas tidy, laundry for kids, etc.). Preference for a sitter with first aid knowledge and previous childcare experience. We’d like someone who can be flexible with weekend shifts and occasional longer days during holidays. The kids are 5 and 8, so ideas for age-appropriate activities are a plus.
