Our DD16 is very, very similar to Mana's description of her DD. And I agree, I think she sees patterens much more easily than others, and the is part of what explains her areas of relative strength- very early reading, math, foreign language and music. She finds music theory comes very easily, and seems to find things like composing and arranging music cone naturally, seeing patterns and relationships. Like Mana's daughter, we never had concerns about comprehension, spelling was easy and basically automatic. And she also had traits which could be considered ASD-ish, but which are completely absent now (mainly sensory, loud-noise aversion and anxiety, emotionally hypersensitive.)
