For example, two neuropsychs missed entirely why my son has trouble staying seated and why he would slip out of his seat during testing and wiggle about just like that little girl in the video... Their minds immediately went to adhd when they see that. Even though both were very, very well aware he has low muscle tone. To me, what that girl does and what my son does looks completely from different from a child who "can not stay in his seat" due to adhd. But both has trouble staying seated.
