Occasional Childcare Needed for 2- and 5-Year-Olds in UK

We are looking for a trustworthy and flexible babysitter for occasional childcare at our home. We have a 2-year-old and a 5-year-old who occasionally need supervision in the evenings or during weekend afternoons. Tasks include feeding snacks, light playtime, helping with bedtime routine, and ensuring a safe environment. Preference for someone with first aid training and experience with toddlers. We’d like someone who can commit to short notices and communicate clearly about plans. Light house rules apply, and we welcome a friendly, patient, and engaging approach with children.
