The second subtype is dyspraxia, or the “fumbler.” This child will have difficulty planning and executing actions. If you hand him a box, for example, and ask him to do something with it, he won’t know what to do. A neurotypical child will say, “I can climb in the box. I can go under the box. I can push the box.” The fumbler will struggle to come up with an “action idea.” He’ll prefer toys, games, and situations that are familiar, instead of novel — new situations require new motor planning, and a child with dyspraxia will shy away from that.
The final category of SPD, sensory-based motor disorder, has two subtypes. The first is postural disorder — let’s call this child the “slumper.” The slumper has difficulty with movement, and moves in a clumsy, disorganized way. He may have difficulty stabilizing himself. He may struggle to run without tripping over his feet. Kids with postural disorder have difficulty crossing the midline, or using the hands and feet on one side of the body on the other side.
