Consider that for some children with sensory irregularities, going into a noisy room, dealing with lights, or being exposed to certain touch or smell or taste sensations, can be as difficult or threatening as putting a hand in a fire.
It may be hard to imagine, but once there are threats to personal safety, invisible to others, behaviour is no longer a choice.
The most useful thing is to deal with those irregularities with a neurodevelopmental program. Meanwhile, it’s about recognizing that some things are just not easy for some people.
They’ll likely do better if they are protected, accommodated and not judged, and if their attempts to cooperate are acknowledged.
