Developing Vision. Green

The first months of life, infants see the surrounding world very differently than adults: at first, babies perceive only black and white, then warm red and yellow are added, and afterward - blue and green.
The accordion book "Developing Vision" is... intended 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 passive, and later active vocabulary, learning simple words, shapes, and colors.
The accordion book can be viewed both in the crib, and in the playpen, and on the play mat. Lightweight and miniature, it folds compactly, making it convenient to take with you. The book is safe for children: made of thick cardboard with rounded corners.
