My two and a half year old son absolutely loved it and Could not put it down. The factthat it is a tiny book suits his little hands even better. I remember reading the same story but from the regular-sized book to him and he barely what interested - Perhaps it has something to do with not being able to have a full view of the pictures with colors filling up most of the page. This is not the case with his tiny book as the tiny pictures filled the tiny pages very nicely. I would recommend this book as an Effective Means to stirring a child's interest in books and reading. I Know That My Son for this book is and wants to be his all time favorite. Eric Carle has at unusual way of capturing my son's imagination and fascination!
