Notice she already knows where the letters are - she learned most of the keyboard more quickly than I'd have believed, in just a few minutes a day with me typing on my macbook. It must help not to be saddled by our adult notions of what order the letters "should" be in. I also love how she can often find ambiguity in statements I've forgotten are ambiguous, thanks to all those shared assumptions that she doesn't share. What does "two Ms" mean? Her interpretation makes more logical sense than what I meant to convey.
Writing is very difficult - when do kids develop the muscles to make it possible? I would guess she'll be typing before she's writing. Has anyone out there with an older kid than mine tested that theory?
