Developing Vision. Blue

In the first months of life, infants see the surrounding world quite differently than adults: at first, babies perceive only black and white, then warm red and yellow are added, and later blue and green.
The accordion book "Developing Vision" is... designed for children from birth. Contrasting black and white patterns are used to stimulate vision, focus, and concentration. Simple colorful pictures contribute to the development of initially passive, and later active vocabulary, learning simple words, shapes, and colors.
The accordion book can be viewed in the crib, in the playpen, or on the developmental mat. Light and miniature, it folds compactly and is convenient to take with you. The book is safe for children: made of thick cardboard with rounded corners.
