This is one of those items that looks uninteresting to grown-ups, but is completely dazzling to newborns. When a baby is first born, her eyesight is not fully developed. Which means baby can't actually SEE all those cute pastel mobiles and stuffed animals. But she is able to see high-contrast images! Books like these are visually stimulating and hold baby's interest- strange but true! Recommended for ages 0 to 2!
