You can read a review by Madina from Berlin, Germany about high contrast black and white baby book "Good Morning, Son».

"I bought the book "Good Morning, Son" as a gift for my friend's baby, after I'd read that the high contrast visual patterns are perfect for optical system development. I was surprised that she looked at the pages for so long ... until her older sister seized it and used as a coloring book.

I would recommend the book to my friends - as a present to a baby or even a toddler.»
