How to Publish a Children’s Book: Reflections From a New Author

Author Dr. Betty Choi explains how to publish a children's book

After Human Body Learning Lab was published, many friends opened up about their dreams of publishing a children’s book. How did you publish a children’s book, Betty? What are the steps to getting started?

Publishing is a long, humbling, and often lonely process…but it’s also very fun and rewarding! These days, new authors have many options when it comes to publishing “kid lit” (kids’ literature).

To demystify the process, I’ll simplify the key steps and explain how I got the chance to publish my first children’s book.

How to publish a children’s book and become an author

First things first! Let’s learn about the industry. Here are the two main paths to publishing a children’s book and the pros and cons.

1. Traditional publishing

The vast majority of books in libraries, schools, and bookstores are produced by traditional publishers.

Often called “the big 5”, the largest publishers are Penguin Random House, HarperCollins, Simon and Schuster, Hachette, and Macmillan. These large publishing houses have many imprints (smaller publishers) as branches of their company. There are also other reputable medium and smaller publishers (see chart at the end of the post).

When an author signs a contract with a publisher (or an agent who serves as your broker), the publisher helps the author create, edit, print, distribute, and market the book. Traditional publishers are also responsible for finding the right illustrator for each children’s book.

Since traditional publishers take on the financial risk of production and promotion costs, they are selective about working with new authors. This leads to the main drawback of traditional publishing: authors are often rejected for years before publishing their first children’s book.

2. Self-publishing

These days, many authors publish children’s books on their own. In other words, self-published authors find their own illustrators, editors, and designers. They also manage the printing, distribution, and marketing of the book.

Self-publishing can be a a great adventure for someone who likes to be hands-on with all the steps. It might also be the best option for niche writers who might not otherwise get accepted by a traditional publisher – or anyone eager to publish without waiting.

Although self-published authors have much control over the production process, overseeing every responsibility can be overwhelming. In addition, the author bears the burden of all costs and risks. Getting the book into schools and libraries can be much more challenging unless the author is well-known in their niche.

However, if self-published authors have a large platform and a good connection with their target audience, this could be a financially rewarding option. Companies like Amazon KDP have also made self-publishing more accessible, affordable, and attractive for new authors.

Research children’s book categories.

As you write your first draft, study the main types of children’s books. This will help you focus on the target age, reading levels, and word count as you write.

If you have a protagonist in your book, remember that characters are usually around the same age or a couple of years older than your target reader. Here are the various types of children’s books by age, level, and genre.

Age levels

  1. Board books (age 0 to 3; 0 to 100 words): These durable baby and toddler books have mostly pictures and few words.
  2. Picture books (age 3 to 8; 250 to 500 words): These books dominate the children’s book market. They have full-page illustrations with a few sentences per page.
  3. Early readers (age 5 to 9; 1500 to 2000 words): As children learn to read, these books build stamina, fluency, and confidence. Simple sentences and paragraphs are paired with supporting illustrations.
  4. Chapter books (age 6 to 10; 8,500 to 12,000 words): For children ready for longer books, these books have short chapters, a simple plot, and few illustrations*.
  5. Middle grade (age 8 to 12; 25,000 to 50,000 words): These novels for fluent readers are typically a couple of hundred pages with more complex, kid-friendly plots and few illustrations*.
  6. Young adult (age 12 and up; 50,000 to 75,000 words): These long novels have adult themes and dramatic plots.

*Note that graphic novels and non-fiction books for big kids and tweens have plenty of rich illustrations!


As you prepare your draft, research children’s books in your genre. Within the main fiction and non-fiction genres are several sub-genres:

  • Fiction: Contemporary fiction, fantasy, fairy tales and fables, historical fiction, mystery, science fiction, horror
  • Non-fiction: Biography/autobiography, history/science, self-help

Understanding genres will help you visualize where your book will sit on a library or bookstore shelf. It’s helpful to think, “If readers like X book, what other books might they like?”

Determine your publishing goals.

Most children’s book authors cannot make a livable income from the advances and royalties. You must truly love and believe in the work and have low expectations about money.

Before you publish, it’s important to ask these big-picture questions:

  • What’s your motivation for writing a children’s book?
  • What are your long-term writing goals?

Dive deep and consider more specific questions:

  • Are you hoping to broaden diversity and representation in Kidlit?
  • Are you an expert passionate about helping children understand a complex topic?
  • Does your imagination drive you to share creative and entertaining ideas with kids?

Since publishing is so humbling, you must pen down your motives.

This will help you see the light at the end of the tunnel, no matter which publishing path you pursue. It will also help you weigh the pros and cons of traditional versus self-publishing.

Common questions about children’s book publishing

How long does it take to publish a children’s book?

The time frame is variable and depends on whether the author is self-publishing or working with a traditional publisher.

Traditional publishing typically ranges from 9 months to 2 years from contract to bookstore release. Of course, this does not include the many months to years spent writing the book!

In comparison, indie publishing is speedy; books and ebooks can be published within a few months of writing.

How do you publish a children’s book the traditional way?

If you’re curious about traditional publishing, these are the main ways publishers connect with new authors.

  1. You pitch your manuscript to an agent who then pitches to publishers. This is the most common scenario for children’s book authors.
  2. You pitch your manuscript to a publisher directly. Large traditional publishers usually do not accept unagented submissions. However, smaller publishers and academic presses will accept proposals directly. This is usually stated on their website.
  3. You write for large media outlets or your own website and social media. Then, an agent or publisher discovers your work and invites you to pitch a manuscript. This is common for celebrities. But it’s also possible for regular people like me!

From pediatrician to author: How I published my first children’s book

Publishing journeys always begin before the first draft. During college and medical school, I loved making summary sheets for my science classes and sharing them with friends and classmates.

How to publish a children's book tips from the author of Human Body Learning Lab

In more recent years, I worked for a large medical education company and would get nerdily excited about creating clinical vignettes, explanations, and visual diagrams for doctors-in-training.

Meanwhile, every conversation with a young patient at the hospital and my children at home was an opportunity to make learning relevant and meaningful. In 2016, I started drafting ideas for Human Body Learning Lab, and the book was published in November 2022!

Human Body Learning Lab is the first children’s anatomy book with kid-friendly science facts, practical health tips, hands-on activities with household materials, and beautiful, diverse photographs and realistic images.

All of this was inspired by my experiences as a pediatrician, medical writer, parenting/education blogger, and homeschooling parent.

When I first started drafting and doodling ideas for the Human Body Learning Lab book, I was working on another passion project.

I paused the science book ideas intermittently while focusing on my bilingual parenting website, Chalk Academy. I never imagined our family’s language journey would grow into an encouraging, worldwide community. (Huge thank you if you’ve been reading my work since then!)

In 2020, when schools shut down during the pandemic, I wished I had finished writing that human body book. Coincidentally, Storey Publishing (an imprint of Workman / Hachette Book Group) reached out to me! My children adore their beautifully crafted and interactive books, so I was incredibly excited and honored.

I am forever grateful to my friend Agnes of Hello, Wonderful for recommending my Chalk Academy work to Storey Publishing. Storey trusted my extensive experience with medical writing and educational content creation.

The publishing process took over two years from my first conversation with Storey Publishing until book launch day.

During the peak of the pandemic, I powered through my manuscript while homeschooling my children. My most productive writing often happened in the middle of the night, the only quiet time when my kids were asleep.

I’ll share more about my manuscript writing, formatting, and organization process in a separate post…Stay tuned for the details! 🙂

If you’ve read Human Body Learning Lab, please leave a rating or review on Amazon! This will help bookstores introduce the book to more parents and teachers.
