Keep baby entertained and learning on the go with Little Hands Stroller Books. Babies are born with undeveloped vision and researchers have found that they strongly prefer high-contrast images that stand out in their blurry new world. With a convenient strap that attaches the book to a stroller, each of these durable board books features colorful, high-contrast illustrations on lively, patterned black-and-white backgrounds. Little ones will be enthralled as they develop their vision and language skills, as well as hand-eye coordination.
