Children's books follow tighter, more specific conventions than adult fiction: word counts are shorter and more exact, age category shapes nearly every other decision, and illustration is often central rather than optional. Getting the category, length, and structure right matters more here than in most adult genres, since gatekeepers and parents alike are quick to notice when a book doesn't match its shelf.
This guide covers the essentials: age categories and word counts, how to structure a picture book, working with an illustrator, and what's different about self-publishing for young readers. Each section links to a full article when you want more detail.
Nearly every other decision in a children's book, word count, page count, plot complexity, protagonist age, how much of the story the illustrations carry, follows from which age category you're writing for. Writing to the wrong length or complexity for your intended age band is one of the most common reasons a children's manuscript gets rejected, or simply doesn't find its audience once published. See Children's Book Age Categories and Word Counts Explained before you get far into drafting.
For picture books especially, illustration isn't an add-on to the text; it carries a real share of the storytelling, and the best picture book texts leave room for the art to do work the words don't. This changes how you write, and it makes finding the right illustrator one of the most consequential decisions in the whole process. See Working with an Illustrator for Your Children's Book.
Children's books follow the same broad production path as any other book, beta reading, editing, cover and interior design, self-publishing setup, with a few category-specific considerations layered in:
See the Complete Guide to Beta Reading, the Complete Guide to Book Editing, and the Complete Guide to Self-Publishing for the fuller versions of each stage.
Beta reading for children's books works a little differently than for adult fiction, since your actual readers (children) often can't give the same kind of structured written feedback an adult beta reader can. Many authors rely on a combination of parents, teachers, librarians, and older children reading aloud with a younger child, alongside adult readers evaluating the manuscript for clarity, pacing, and age-appropriateness.

Entrada Publishing offers beta reading, editing, and publishing support for children's books across age categories.
The standard categories, roughly, are board book (ages 0-3), picture book (3-8), early reader (5-9), chapter book (6-10), middle grade (8-12), and young adult (12-18), each with its own typical word count and conventions. See Children's Book Age Categories and Word Counts Explained
For picture books and most books aimed at pre-readers, yes, illustration typically carries real narrative weight. Chapter books and middle grade novels use illustration more sparingly or not at all. See Working with an Illustrator for Your Children's Book
In several ways, including illustration coordination, print specifications (often full color, different trim sizes), and how the book gets discovered, since children's books are often bought by adults for children rather than found through the same search behavior as adult fiction.

Beta reading works a bit differently here, often combining adult readers evaluating clarity and age-appropriateness with parents, teachers, or older children giving reactions closer to your actual audience. See Beta Readers for Children's Books
