I am not sure if this is SPD or not. My son is 3 and asd. He likes to jump a lot, spins himself in circles and looks to the side, just started doing that again recently but not only once in a blue moon. He use to do that a lot before. When he uses the iPad for his activities and if anything goes across the screen, like positive reinforcement when he does something right, he will follow it with his head and eyes across the screen. He will draw lines and circles with his finger in dirt, sand, rice. I am not sure if this is SPD or his symptoms related to autism. He is on gfcfsf diet since feb and after about 1 1/2 mths a lot of these issue seem to go away, except for the jumping. I know a lot of autistic children have SPD. I was just wondering.
