What do we commonly refer to as children's books?

Children's books cover books for ages 0 to 18. Therefore, YA (young adult) books also fall into the children's book category.

It will be clear whether your book is for children or teenagers. But let's look at some more specific subcategories.

Below is a list of age groups and the different kinds of books for them:

Newborn to age 4: Picture books in the form of board and soft books
​
Ages 2–5: Early picture books

Ages 5–8: Picture books, coloring, activity and novelty books

Ages 4–8: Early readers

Ages 6-9: First chapter books and graphic novels

Ages 8–12: Middle-grade novels and graphic novels

Ages 12-18: Young adult (YA) novels and graphic novels

* Nonfiction books also exist for all these age groups

Stories, word counts, and book types vary by age, but most illustration styles are suitable for all ages. So your options are varied. Young adult books rarely include illustrations (especially on covers), but they may include them.

Above all, I like books that contain lessons and touching stories that anyone can read comfortably in their own style. Below is an example of a children's book by Maira Kalman.

* Maira Kalman: She is an American artist, illustrator, writer, and designer known for her painting and writing about the human condition. She is the author and illustrator of over 30 books for adults and children and her work is exhibited in museums around the world.

Below is Maira Kalman's adult book :

​Her illustrations have been frequently featured in the New York Times, and her writings and pictures are uploaded in the form of an illustration blog, giving readers special emotion and fun. She also writes articles and columns with political content on 'the right to pursue happiness'.

​When you look at her paintings, you don't think that children's books are that complicated and difficult. It's not that her skills are lacking, it's that she's a great professional and even though she's good at drawing, she puts her best foot forward and shows the message she wants to convey. In other words, you can create a good children's book if you think about how to convey the message you want to convey to each age group.
