British family looking for helper

Our helper is moving home soon so we are searching for a new helper to join our family. We are a family of four - our children are 9 and 8 months - and we also have a dog, Simba. We are both teachers at an International School. We are looking for someone to look after our baby whilst we are working, and cooking, cleaning and walking the dog. As well as every Sunday, we can offer most Saturday afternoons off as well. As teachers we do get a lot of holiday time and (before covid!) would travel.
