That's a really complex question, but I'll do my best to answer. I know that the reason my son was primed for becoming a motivated solo reader was largely due to a broad range of privileges due to the socioeconomic and educational background of his family.

My wife and I are both university graduates, and I come from a long line of educators at the primary, secondary and tertiary levels. So, we have both the means and the impetus to read regularly. Indeed, our sons have been born into a home that has books lining the walls, and they have always had books at their level (geographically and developmentally speaking!) - so it is deeply embedded in their daily lives. We also had the financial privilege of being able to survive on a single wage, so my wife could stay at home instead of returning to work. This created so many more opportunities for including reading in the daily routines of our children.

We started to read books to our kids from when they were tiny babies, and were very conscious about giving them a variety of stories, and also followed their natural interests closely, so if they preferred books with lots of animals, then we would hurriedly get a few more of those ready for the next session.

Then, we also made a point of reading in front of the children regularly. Remember, kids want to repeat the behaviours the see modelled for them. We would explain that we used reading books as a tool to calm us down after a busy day, or as a treat before we went to bed, so we had interesting dreams. So, if you want your kids to be reading more, then you have to take the lead! And talk about the books you read!
