Demographics matter the most in the field of book writing. If you fail to understand who your target audience is and what they would prefer to read then you surely have not understood the core essence of writing books. If you observe children then you will see how their interests in books vary. Some tend to prefer picture books while some look for an interesting story so you have to take care of all of these factors before you proceed to write a book.
While adults are not complicated, readers. They would not prefer reading content that is bloated with pictures but a child would. With that said, you should know that there exists a correlation between content and illustrations for children’s content and that is exactly why it is better to
hire a children’s book illustrator. I am looking for an illustrator myself but I have not found one yet. Would you people suggest me any?
