Initially Scary, Now Beloved Animal Sounds Book
Format: Board book
Got this for my 1.5 y.o. for the holidays. She was initially scared of the sounds (which are pretty loud and not volume adjustable). We read it several times without hitting the buttons. Then I would occasionally push some of the buttons for her. Later she got bolder and started playing with it by herself, pushing them at random and perusing the book. Now she has the positions of every button memorized and loves this book. We call it the Big Book and it was in the daily rotation for weeks. We still pull it out from time to time, and she is able to play with it independently as well as have us read the stories to her. Totally worth the money and shelf space. 10/10 would buy again.

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!
