Is arm flapping in an 8 month old normal if all developmental milestones are achieved?
Hand flapping is one of many ways a developing child stimulates their neural development. If you feel it is excessive, talk to a pediatric neurologist. Hand flapping by itself is not an indicator of autism but then most doctors will not confirm a diagnosis of autism until milestones have been missed, usually by the age of 3. Watch and record her milestones. Talk to her pediatrician. One thing in her favor is that autism (while found in girls) is found predominantly in males. The odds are in her favor. If things persist over time occupational therapy and sensory integration evaluations may be in order but not this early. Seeking additional neurological stimulation can be a temporary phase, could indicate early ADD or other conditions known for sensation seeking activities. At this point there is no way to know. Like I said, if it seems truly excessive take her to be evaluated. Just don’t be surprised if they tell you to come back later for a better evaluation.
