Disclosure: I received this book in order to give my honest opinion.
Tiffany Papageorge created a is a beautiful story called My Yellow Balloon that is designed to help with grief. The thing that struck me about this book is the beautiful colors. I was awed by the illustrations. I felt like this story was along the lines of Pixar's UP giving you a glimpse into a subject that is hard to comprehend and breaking it down so that you can feel the emotions and learn to deal with them. I would highly recommend this book for anyone who loves a child who is dealing with a loss that they don't quite understand.
This book is available on Amazon right now.
