Babysitter wanted for childcare in Polinyà

Hello!
We are the parents of two little ones aged 8 years and 2 and a half years old. We are looking for someone trustworthy who can help us occasionally, one or two days during the week, from approximately 4:00 PM to 8:30 PM or when Dad arrives, picking the children up from school and nursery (by car), bringing them home and staying with them until I return or their father arrives. Maybe help preparing dinners (something simple like nuggets or Pescavilla).
It's not weekly, it's approximately once a month. We also need help when one of the children is sick, especially the little one, and cannot go to nursery. About them:
The older one is very independent: he showers himself, organizes his things, and does his homework without help. He just needs to be reminded to get on with it. He is a curious, sensitive boy with a lot of imagination. The little one is cheerful and very active. He loves to move, explore, and needs more attention and play. I am looking for someone responsible, caring, and patient, who enjoys children.
