Fun animal book with Eric Carle illustrations!
Format: Board book
Some of the noises the animals make feel a little strange, but my toddler loves to push the buttons! I do like that it says the name of the animal before making the sound the animal makes - gives some vocabulary practice when my daughter is reading independently.

All the grandkids enjoy these, of various ages.
Format: Board book
The grandkids always enjoy Eric Carle sound books. The older one reads the stories and the younger one likes to just push the buttons and listen and then say what the animal is. The sound is always nice and clear and the photos on the buttons are easily recognizable. As an added bonus these were offered at a great holiday price.

Fintastic storytelling
Format: Hardcover
Awesome book for shark fanatic kids. I bought this book for my 7yr son and it was so informational that I even learned something . And if you would just like to read the book you can and in between you want switch and l3t the story teller read. They are both fun for a lil boy to read with someone or the storyteller.
