"didn't consider my DD to be reading when she was "reading" the books she had memorized, or any little sight-word primers and things, but when you handed her something she had never seen and could read most or all of the words, stop at words she didn't know and try and sound them out. Or when she started reading streets signs, ceral boxes and things. It's sort of the wild spill-out after the breaking of the code."

Yeah, that's how I define it, too.
