Grandkids love the book and especially the flashlight.
Format: Board book
All of Eric Carle's books are great. My 2 1/2 yr old granddaughter is especially interested in flashlights these days, but household flashlights are too bright for kids who tend to flash them in people's faces. This is a low-beam flashlight that compliments a fun book and she loves them both.

Fun interactive pop-up book
Format: Board book
My 2-year-old loves fireflies, thanks to Grandma teaching him to “catch and release”. She then gave him this book to further encourage his fascination with fireflies. The book is a pop-up book and each pop-up has a round hole to shine the included flashlight through to make the fireflies in the book light up. To add to the fun, there are buttons to push to make sounds to accompany the story. Too much fun! Saw this at the store at a higher price, found it here at a discount. Worth every penny!
