Repetitive Behaviors

          There are a number of odd repetitive movements that children with ASD exhibit that may set them apart from other children. These behaviors might be extreme and highly apparent or more subtle. Some of these children spend a lot of time repeatedly flapping their arms or walking on their toes while others suddenly freeze in position.

          As children, they might spend hours lining up their cars and trains in a certain way, rather than using them for pretend play. If someone accidentally moves one of the toys, the child may be tremendously upset. Children with ASD need, and demand, absolute consistency in their environment. A slight change in any routine-in mealtimes, dressing, taking a bath, going to school at a certain time and by the same route - can be extremely disturbing. Perhaps order and sameness lend some stability in a world of confusion.

          Repetitive behavior sometimes takes the form of a persistent, intense preoccupation. For example, the child might be obsessed with learning all about vacuum cleaners, train schedules, or lighthouses. Often there is great interest in numbers, symbols, or science topics.
