No. I am not implying a chicken and egg problem. If you generally start to learn how to read with 6 what would do get from a book between the age 0-5 when you cannot read? In another thread someone explained that usually parents "read" the book to the child - child answered my question. My parents never read books to me so I did not know this was common.
I don’t remember my father teaching me to read but he was an avid reader and I was reading well before six. When I in the third grade I won the library summer reading contest - I read all my books and all my sister’s books (she was in first grade) - I read like 60 books, my sister 20 and the high school winner ten :) We moved and had a bookmobile at our new location and I would get a paper grocery bag of books every week.
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).
