Developing vision from 0 to 6 months

The "DEVELOPING VISION from 0 to 6 months" fold-out book is a set of 8 double-sided cards that unfold like an accordion.
On one side, you'll find 8 black-and-white images, and on the other, 8 illustrations using four primary colors.
The book will help develop your baby's vision from birth. Using contrasting black-and-white pictures and images with a minimal number of colors is a very popular method abroad for stimulating children's vision.
