“We had a policy on books from the very beginning with our children; they are an essential need not a luxury. You can have as many as you like. A Christmas tradition soon developed. Each year they got a book stack – a selection of books wrapped individually in different coloured tissue paper and joined into a bundle with a large gold ribbon with the largest book at the bottom, the smallest at the top. … Not cheap, since you need at least eight books to make an impressive stack, but one that has, I think, helped to keep their love of reading going.”
