For context I have audhd. I’ve always been confused about the association between stacking toys and autism. I don’t particularly remember stacking toys as a kid other than of course I did because I was a kid. Don’t lots of kids try to stack stuff as high as possible occasionally? Why is this seen as an autistic trait? Is it a stereotype due to the historical bias towards autistic boys with a particular presentation or something else? If it really is associated with autism and not a bias, why do autistic kids do it more?
