My 1 year loves this book. It's bright and colorful and really holds her attention as we learn the alphabet.
I got this set of books when my daughter was 10 months old and she immediately loved them. She's now 16 months old and they are still some of the first books she reaches for when she wants to read. She can identify many of the pictures in this book. As her development continues we can use the pictures she already recognizes to learn about the alphabet. I loved these so much we now have the smaller (travel sized!) set as well.
