Children with autism like to immerse themselves in their own world, so their social interaction skills are poor, and communication with children can be conflicting. Sometimes the child tends to play alone, especially because the child has a narrow range of interests and stereotypical behavior. The child is particularly interested in some inanimate objects and has strong attachment to them. For example, the child is particularly interested in running water, rocks, hair, bamboo sticks, and various inanimate, fixed objects. Patients may become immersed in them and behave in a relatively rigid manner, for example, by insisting on a certain path or by placing objects in a certain way. These symptoms are all related to autism itself. As an adult, parents should observe and communicate with their children to develop self-care and self-care skills.
