Research has indicated symptoms in infants that indicate autism spectrum disorder. Describe these symptoms

What will be an ideal response?

Infants with autism spectrum disorder are often described as being "too good" and never crying. They lack social interest, do not play interactive or imitative games (such as peek-a-boo), are extremely sensitive to touch and sound, and have abnormal sleep patterns with nighttime awakenings that last for several hours. They also have rigid eating behaviors, refusing to eat certain foods because of the smell, texture, or taste.
