This book was for my two great grandsons aged 4 and 3. They were amazed to see a book who's two main characters were themselves. I was delighted to see the look on their little faces as the story was read aloud. I bought this book as a keepsake for them , something for them to enjoy for many years and then hopefully to read to their own children one day , so to be able to put my own inscription inside was a real bonus. I'm so happy with this book, I would highly recommend anyone who wants to see a child's face light up to purchase one too, its worth every penny.
