There's no reason to wait until a child is six to teach them to read. I was reading much earlier, before formal schooling, because my parents were readers and read to me regularly. I had a tremendous enthusiasm for books because books were important to my parents.

Plenty of research indicates reading to kids from a very young age improves their education outcomes later in life.

I'm sorry your parents didn't know to do that. Hopefully now that you know, you'll read to your kids (if/when you have any).
