DD is no savant, but had some vaguely savantish traits as a toddler that could also have been considered ASDish (or gifted). In particular, she memorized the location of most countries of the world and many, many flags of the world as a young toddler (twoish) and could recite extremely long picture books with ease within a few hearings. I feel like these unusual memory skills have receded somewhat, although maybe they are just more underground. She looked more odd/off as a toddler than she does now, that's for sure.
