I would say this book is useful for babies who are 6 months +. Nevertheless my son gets excited seeing this book. Kids for sure will love it for the colorful things in this book. The touch and feel arts are present in all the pages.
My 5 month son just loves to look at the book. It's a good plaything to spend time with the baby and teach him about the colour and textures and animals. The mirror is another attraction for baby. Highly recommend it.
