Is arm flapping always a sign of autism?

NO, it's not always a sign. Many children flam their hands and arms and are neurotypical. By itself, hand or arm flapping is not a red flag. If you have concerns it is always good to talk to your pediatrician though.

    It could also just be startle reflex and then they realize moving their arms is a new cool thing they can do!
