My son was given this book at birth! At six months when he was sitting up, I would prop the book in front of him and he would look at all the pictures which are grouped into themes on each page (boats, planes, neighbourhood etc). At one he was pointing to all the images and I was describing the scenes. Now at two years of age when his vocabulary is expanding by the moment he reads this book more than any other. I point to things and ask him to name them - he describes what he sees - it is a great source of knowledge and vocabulary for him, and is the one book, guaranteed to distract him when a meltdown is approaching! I can't recommend it enough - both for its contents and its longevity as a book that is appropriate for many years.
