Babies show a special interest in faces, and in this high-contrast baby book, they learn about faces and facial expressions while the short, onomatopoeic texts stimulate their sense of hearing. The baby book "Aki the Red Bunny" is suitable for babies from 5 months old and is optimally designed for baby eyes. It supports the development and vision of babies. Babies see things blurry, which is why they love high-contrast illustrations. This baby book contains high-contrast images in black and white and primary colors, predominantly in red – the first color that babies can distinguish from others. Babies recognize the color red from their time in mom's belly; therefore, it is the first color they can identify from birth and it provides comfort. Scientific studies by British psychologist Prof. Anna Franklin also show that babies love red.
