Nanny to mind 3 children in our home

Hi We are a family of 5. We have 3 children who are aged 5, 3 and 1. Two boys and 1 girl. We are looking for someone who will mind our children in our home. The eldest boy will attend primary school every day until 1:30 and the middle child will attend montessori until 1pm everyday. Our youngest boy is 1.5 and will be at home all day. We are looking for a minder to bring the two eldest children to school and collect them from school in the afternoon. The kids are energetic, They love spending time outdoors on their scooters and bikes and loving playing at the playground. They love colouring too. The hours are part time as I jobshare. The hours for one week will be 37.5 and the hours the second week will be 16 hours. 8am until 3:30pm on the week I am working and 9:30 -1:30 Monday-Thursday.
