ICYMI: Moon sand is among the highest rated toys for kids with sensory integration disorder. Moon sand doesn't dry out and is light to the touch. It can be used several times over and it's safe to sanitize it if you need to. Moon sand also comes in several different colors including white, blue, purple, and pink. It's great for kids who shy away from touching anything and ones who love to pick up everything in sight. For a toy that's better for developing motor skills, check out a Koosh ball. Koosh balls are squeezable and are also used as stress balls. They're about three inches in diameter, so they're great even for littler kids, but only recommended for those who are three or older. http://dlvr.it/RkrMK3
