Kids learn to read best out of interest -- with reading material they are interested in and when they are ready to learn. And it makes them better.
My parents fought not to teach me to read. I didn't learn to read until I was 11. When I was 12 I went to school for the first time (unschooled) and was the top reader in my academically inclined private school.
Everyone else learned phonics and other permanent reading crutches and I read shapes because I wasn't told how or when to learn when I was little.
I still read weirdly fast compared to classically trained people who are otherwise smarter than me. What is faster I/O worth to your future?
All it involves is not ramming phonics and other Prussian nonsense down your kids throat and waiting for intrinsic motivation to kick in.
