Get the Butter Flapsmug. Some children with autism “hand flap” as a self-stimulatory behavior. Other self-stimulatory behaviors sometimes seen in children with autism include rocking and spinning. These behaviors help them calm themselves or regulate their emotional states. Children may also do it when excited or upset, and it can be very hard to distract an autistic child away from their self-stimulatory behavior.
