On one side, it might be nice to create stories that fit a specific want/desire for what a child might need. We might even go for the concept of a segment of one kind of story.
On the other hand, I am picky with the stories I read to my child. I see stories I read as education. They transmit some non-conscious cultural things about being human, about handling this reality and the world.
For me the books I read to my kid are the future equivalent of people telling stories around the fire to transmit some necessary and vital knowledge thousands of years ago. I believe (without a scientific ) they are shaping both my child how my child sees the world (through words construct and imagination) and my child value system.
Of course, I am trying to expose him to various stories and books as I am also not sure what I think is important is actually important for his life.
But I am a bit reluctant/skeptical whenever I buy a book launched recently. I am not 100% sure if the author just wrote a story because they want to sell something, and it does not have any other meaning. Don't get me wrong, it is ok to just buy a book because it looks nice, even if it is shallow. But there are so many books that I don't want all the books to be the same.
