This plush, friendly, lovable snake is the ideal partner for children who need to do a lot of squeezing and touching. Each of the 6 sections has a different feel (foam, memory foam, beads, vibration, marbles, quiet rattle), that encourages touch and manipulation giving hands and fingers a great workout. A terrific companion during circle time, homework time or snuggling down to sleep. Pull string vibrator. No batteries needed. Did you know vibration offers calming and organizing input for most people? The activation of touch receptors and deep receptors is why massage is so relaxing and invigorating. The mouth and face have enormous sensitivity. By providing chew opportunities that involve vibration, very often a child can organize and calm down. It is important to allow individuals to explore vibration on their own terms and pace. Whether an individual has hypersensivity or hyposensivity, vibration helps to “normalize” sensation.
