Use Visuals to Overcome Stress
This technique is perhaps the most useful because children with ASD are typically more visual learners. Consequently, the use of photos or schedule pictures can be effective in helping them understand what to do when they are irritated or even violent.
For example, if your child is afraid when left alone, having a picture of family members playing together can be relaxing.
You can also use visual schedules to help your child overcome stress caused by changes in routines. Having a picture showing that there will be no regular music lessons during the school vacation can be used to prepare the child for changes. You should look at the chart regularly with your child to make them understand that the program will change soon.
