Children Educational Audio Books

When I was a kid, I used to have a good memory (actually I still do). But at that time, I was quite lazy, especially concerning everything related to studying. So my mother used to have a hard time pushing me to study, and often in spite of my good memory, she couldn't get me to learn and memorize things, and at school, especially at that time, there were lots of things to memorize.
... Until she got the idea to record lessons for me (on tape), and to play these lessons to me at night before sleep or in the morning at awakening time. Recording school lessons on tape is not that straight forward, my mother had to repeat the same sentences again and again, and sometimes she used to record me trying to give answers (often incorrect ones), and to record herself correcting me aloud. Still without knowing, my mother had tapped in the world of educational children's audio books, and she maintains that it was the only way to make me memorize things.
So my reflexion today is about the untapped world of educational children audio books, not only the ones that children could listen to consciously, but also about the ones specifically designed for subliminal or unconscious use. What a potential they could give your children and from their young age.
But here I would advise parents to choose their kids audio books with particular care, since children are easily influenceable, and if they choose the wrong book, instead of giving benefit to their kids, they could harm them without knowing.
