Apparently I used to headbang when I was a toddler. My sister did not. I remember my cousin used to punch and kick the floor then occasionally he would hit his head a few times against it. However, he usually just stuck to hitting and kicking the ground rather than headbanging.

Kids who are under-stimulated (those who are blind, deaf, bored, or lonely) head bang for stimulation. But children who are overstimulated (in an overwhelming environment) find these rhythmic movements soothing.
For some children, head banging is a way to release tension and prepare for sleep. Some kids head-bang for relief when they are teething or have an ear infection.
Some kids bang their heads out of frustration or anger, as in a temper tantrum. Head banging is an effective attention-seeking maneuver. The more reaction children get from parents or other adults, the more likely they are to continue this habit.
Generally, healthy children do not head-bang in order to injure themselves.
Quote:
Up to 20 percent of healthy children are head-bangers for a time. Typically, head banging appears in the latter half of the first year of life and generally ends spontaneously by four years of age. Boys are three or four times more likely to be head-bangers than girls.
Head banging, head rolling, and body rocking are also each far more common in autistic children, children with developmental delays, and children who have suffered abuse or neglect.
