We are all familiar with the person with Autism Spectrum Disorder (ASD) who needs to keep everything in order. If one thing gets out of order the child may either tantrum or immediately correct the ‘error.’ ... Change is difficult for all people autistic or not. Change presents an uncomfortable position for us. For example, people typically sit at the same place around the dinner table or may sleep on a certain side of the bed. We all have a reaction to change, if somebody else sits in our chair or our side of the bed. It is normal to feel irritated ... This is also true for the autistic person except the person with ASD reacts more strongly and may not know how to regulate himself when a change is imposed upon him.
