The skin contains more than 100 types of receptors sensitive to touch, temperature, pressure and pain. Skin is the body's largest organ, and its sensory receptors are the earliest to develop prenatally. The Sassy Ring-O-Links is a classic toy, an essential for baby’s first toy box! It’s a nine-piece link set that includes a large black-and-white ring to attach all the other links or your little one’s other toys. The vibrantly coloured links can be used to help stimulate your baby’s sense of vision, or help with colour identification at an early age. The multiple textures help provide touch stimulation and offer the perfect grip to help develop your baby’s fine motor skills. Interaction Idea - Shake the Ring'O Links next to baby to catch their attention and to show them how to shake it. As baby develops, show them how the links can unclip from the main ring and clip back on. This will improve fine motor skills and teach problem solving.
