BTW, I recall a study that was conducted a few years ago on the greatest predictor of literacy in children. It wasn’t reading to them and it wasn’t early childhood education. The children who read the best came from homes that had a lot of reading material in them.
Kids are curious little humans and they see books on lower shelves they will pull them off and look at them. Bright colors and pictures help but even books with just prose will be leafed through.
