My son (now almost 6) and I LOVE Mo Willems' books! We were a little late in our discovery of Mo Willems. This book was our first, borrowed from the library on a whim when he was 4. We liked it so much and laughed every time we read it......and we read it over and over until we had to turn it back in! We ended up purchasing our own copy, which led to the discovery of other Mo Willems funny, silly stories. We highly recommend [Willems] Elephant and Piggie series. One of our favorites is "We Are In A Book". Whenever we have a down day we pick up a Pigeon or Elephant/Piggie book and it perks us right up. Perfectly fun for everyone - yes, even mom and dad! And while they are silly, they do include positive messages (sharing, caring, patience, etc.).
The illustrations and dialogue on each page are simple so one does not detract from the other. My son has just started reading and this book, as well as Elephant/Piggie, have become great ways for him to begin reading his favorite stories. The sentences are easy enough for him to read and the larger print is helpful. Because of the minimalist style of the illustrations, there is not a lot of distraction to take away my son's concentration on reading. And because the stories are fun, my son finds reading practice less stressful (he can get overwhelmed when there are a lot of unrecognizable words).
