Repetitive behaviors or interests

Although kids with ASD usually appear physically normal and have good muscle control, odd repetitive motions may set them apart from other children.

These behaviors might be extreme and highly apparent or more subtle. Some children and older individuals spend a lot of time repeatedly flapping their arms or walking on their toes.Some 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. ASD children 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.
