hello, and welcome!
just a note on the reading front - our DS9 didn't decide to read until he was almost 6 ... by the end of Kindergarten he was reading at 4th or so grade level and in the middle of 2nd grade he was reading at 10th and now - well let's just say he can read anything he wants.
Last night I read a reassuring passage from Deborah Ruf's book "Losing our Minds" that essentially said a gifted child in particular will learn something when the conditions are right to learn that thing. In the case of our DS, reading came when he wanted to find information for himself instead of asking questions of us.
so, welcome! again
