Hi there- My 3 1/2 year old son has SPD and does some things that seem autistic though none of the therapists would ever give him a diagnosis of autism (he has been to MANY!) Do kids with SPD tend to get fixated on some things? Like today my son brought home his little place mat from school because school is over and he just wanted to stare at it and wring his hands and shake his legs. The hand wringing and leg shaking is not new, he tends to do that when he has to sit still for long or if there is a lot of noise and activity happening in a room, but he does not usually do it when just staring at an object. I was just wondering if anybody elses kids ever do this? I put the place mat away and I think it is out of his mind now, but I just don't know what to think when he does things like that. Thanks so much for any help!
