Just an update in case this would help anyone else. We had him evaluated by a neurodevelopmental specialist. He said he didn't think it was a developmental problem - just a bad habit. He told us to just ask him to stop flapping. We did "quiet hands" and "we only do that when we're alone in bed" and he has stopped. I guess it was kind of like masturbation - something that felt really good but isn't really appropriate in public. Thanks for all the advice and help!
