I've observed in my research (and in real life) many various impressive renditions of what i call "stupid toddler tricks". i saw a 1 year old count to 20. my own kids take books to bed at 2 and "reads" them to himself.
could the kid do math? could my kid read? No. of course not. you probe a little bit deeper and all the trappings of what we adults call cognisance fall away. the one year old has no idea what they were reciting. my kid repeats (albeit poorly) what he heard us say when . "reading",but a little bit of digging reveals the limits of his comprehension. kids use the pictures and other hints hints as cues, they're (the clever bastards),they have a brilliant verbal/aural ability at such an age, and they can have some kind of basic symbolic ability and rote repetition. And you can get them to do amazing things if you record them doing the trick but don't dig any deeper into their mental processes.
I'm guessing that people who are downvoting don't understand child mental development, have a vastly simpler definition of reading than myself, or don't understand how many layers of development are required to arrive at actual reading that have to be passed first. i do think you could quickly show such a trick to a well meaning person and get the legend started however...
