There is that saying that a picture is worth 1000 words. I've heard also that it takes actually 4000 words to equal the impact of one image.
When your kids are scared of monsters, this book speaks volumes.
Go Away, Big Green Monster by Ed Emberley helped my oldest child when she was having bad dreams about monsters.
The book is interactive, as each page is turned the monster appears, then as the child tells him to "GO AWAY" each page turned makes another part of the monster disappear.
My daughter loved that. We borrowed the book, and read it over and over each time we did. Makes me wish we'd bought it. As my youngest is still 2 1/2 I still may invest in this book because it is just that invaluable for helping kids through the scary monster faze.
