Patricia, looking for a nanny - HP16 Prestwood

I have a 6 year old son, Jacob, who needs collecting from infant school at 3pm each day, a short walk from my home in Prestwood, Bucks. Jacob will have a small amount of homework.

Isabella, 11, will be walking home from her secondary school, arriving home around 3.45pm. She'll have lots of homework to do and just needs to get on with that, which she is enthusiastic to do.

Ideally I would like someone who could cook a meal for them both but that isn't essential. I return from work each date at 5.30/6pm each day.
