Autism isn’t like Down Syndrome, where you’re born with specific physical features. At first glance, autistics seem “normal”. But their posture, motions and eyes often give away that something’s up. Autistic movements may include repetitive motions, clapping or flapping one’s hands or other so-called stims. Due to our lack of sensory integrations, many autistics have bad posture. We just can’t seem to construct one whole out of our many limbs. This might also be the reason why we bump into table corners more often than the average person, and regularly drop things.
