ITA that is it hard to pinpoint when they were "readers." Both my kids were fluent without any teaching from me. In fact, I suspect they both read even earlier than I could identify because by the time I figured it out, they were into 2-3gr books by 4yr. It is also hard to ask parents of GT kids this question because using my first child as an example, we assume whatever they are doing is the norm! I was more attuned to my second child and was totally thankful that she also just "picked it up" since I had never had to teach phonics. I will say that the reading progression with her has been a bit slower than him (or maybe I am just more aware of the milestones since she is the 2nd and last child) but her writing is way ahead of him. Could also be attributed to gender differences. To clarify, by writing, I mean composing thoughts on paper, not handwriting.
