Our Wimmer-Ferguson Loopsy teether and clutching toy borrows on the significance of black and white contrast in helping baby's visual development. Three wooden beads are intertwined with soft, pliable BPA-free loops for teething or gumming babies. These wooden clutching beads are designed for tiny hands to reach for, grab, pull, twist, and gum on, engaging their gross motor skills, and finding comfort during teething time. From Manhattan Toy's award winning Wimmer-Ferguson infant toy collection - the original innovator of black and white developmental baby toys.
