Sweet story
Format: Hardcover
Gave to a 9 year old grandson who has struggled with reading -- looked like a good choice. He seemed initially pleased.

Perfect 2nd Birthday Gift, So Fun and Interactive!
Format: Board book
This book was such a fun gift for my niece’s 2nd birthday! She absolutely loved it from the moment she opened it.
The bright pictures in the classic Eric Carle style are beautiful and really grab little ones’ attention. The buttons are easy for small hands to push, and the animal sounds make it extra engaging and interactive. She had so much fun pressing the buttons over and over again and trying to copy the sounds.
It’s a great book for keeping toddlers entertained.
