One of the more effective methods is providing a quiet spot away from the sensory stimulation. My youngest son, when he became overwhelmed at school, had a small room he could go into, shut the door and stay there until he was able to regain control. My oldest son, who is 20, will occasionally have episodes where he feels overwhelmed. He doesn't throw a temper tantrum, though he has perfected his growl, but when these times hit, he will go to his room, pop in a CD and wrap himself up in his blankets in his bed until he feels better. Points to remember.
Tantrums are often a symptom of the sensory overload that can occur with our children.
Tantrums take place less frequently as the child grows older. As a child with autism grows older, they often develop skills that will help them cope with over-stimulation so that it doesn't always result in a tantrum. As parents, we can help them develop these skills. We can also help them find ways of regaining control when they do experience sensory overload. Used under License.
