I had some of those mispronunciation issues as a kid - I remember going to school in junior K (age 4) and pronouncing 'memory' as something like "mee-MORE-ee".
But more on topic, my DS is two and a half and did his first real definite reading of a word (out of context, no familiar logo/picture/font to work from) in mid-November, so 2y4m. Now at 2y6m he's got a handful of sight words and is sounding out simple CVC words, and asking a LOT of things like 'what does that word say?' or 'what's the question mark for?', and really likes for us to write out words for him on his easel. He asked me to draw a trumpet and 'draw its word' the other day, then looked and said "that has the word 'pet' in it!", which surprised me (probably more than it should have, LOL).
Apparently this is pretty much bang-on, to the month, the exact same timing for when I started to read, so I guess he comes by it honestly!
