You can’t work this backwards though.
I mean if you bought a 500 book library and installed it in a no book neighbor household that wouldn’t do it.
The point is that books are valued and reading is a habit practiced regularly in front of and with the kids. The parents make the time and effort and spend the money to have lots of books for the whole family. And they read, a lot, individually and together.
It’s not an artificial presence of books.
My parents never read to us, but we had an encyclopedia set and got several magazines every month.
I read them.
Well, as my wife reminded me ( but I do remember! ) , we had a small bookshelf in our apartment when I was in grad school, and our daughter, still crawling, would ritualistically pull all the books off the shelf, and leaf through them, not knowing a thing about them or what they meant.
She became a teacher, and still is today.
( And, as a matter of fact, but beside the point, she’s the mother of two of our three grandchildren. )
