The Spectrum and other cognitive disorders are so varied its amazing! Ds was informally assessed using the CARS assessment for ASD by his speechie and scored highly on it, yet Ive had a few people tell me because he is often loving and isnt completely socially inept that he couldnt be ASD. They seem to forget that ASD can vary in traits from child to child.

Sounds to me from what you described your DD could be a Sensory Seeker. My DS is a seeker, which is why he has a huge tendency to be overtly physical/aggressive and exaggerated in his everyday life. If he cant be stimulated by it he doesnt want to know about it. He touches, he tastes, he smells, he even deliberately hurts himself in order to process life. Its quite full on sometimes. If anyone looked at him they'd think I abuse him with the amount of injuries and bruises he has.
