This is a large format book, 25 cms square, and very beautifully illustrated. The cover sets the scene, with sleeping animal and bird by a steam with the title of the book in reflective gold characters that will appeal to children. It is not a thick book, two pages of tips on "mindfulness", and 22 pages of text. Each page has no more than 4 lines of text,. The pictures really make this book special and are so child friendly. They are colourful, very clear, powerful, with no soft edges or impressions or suggestions. They will be immediately recognised and appreciated by young children. The concept is certainly going to be helpful to persuade young children to drift off to sleep, especially if read to them by Mum! If they read it themselves, I am not sure that the "mindfulness" concept would be appreciated. The book is aimed at youngsters of 5 to 7 year old, and I think that most children of that age group would have some difficulty appreciating the philosophical concept, it seems a little too deep for that age group, who are more immediate in their thinking. That said, it is not expensive, and I am sure will sell well, and be appreciated very much by the young folk, even if the concept is lost on them!
