This is a good point that I don't think gets enough thought. Unless he's going to an excellent public school, or a private school, the odds he's much more bored in the first few years of school goes up dramatically when he's reading the book in 5 minutes (or practically has it memorized from reading it at home so much) while everyone else is sounding out the words on the first page. This does all sort of go away if he's going to great school with more individualized attention. The odds of that in general are pretty low, but hopefully a bit better assuming there's some correlation between having a parent that cares enough to teach a 2-year-old to read in their spare time and having the resources to be in a great public district or go to private school.
