Top 10 Mistakes First-Time Children’s Authors Make and (How to Avoid Them)

Writing a children’s book for the first time is exciting—but it can also be a minefield of beginner mistakes. Many first-time authors dive into the process with big ideas and good intentions, only to find themselves stuck, disappointed, or publishing something they’re not proud of.

The good news? Most of these common mistakes are totally avoidable—with the right guidance.

Let’s break down the top 10 mistakes new children’s book authors make—and how you can steer clear of them.


The mistake: Trying to cram in too much plot, dialogue, or vocabulary.

Why it matters: Kids, especially younger ones, need clarity and simplicity. A complex story can confuse or bore them.

How to avoid it: Stick to one main idea or lesson. Use short sentences, age-appropriate words, and a clear beginning, middle, and end.


The mistake: Writing a book for “all kids.”

Why it matters: A story that works for a 10-year-old won’t work for a 3-year-old.

How to avoid it: Decide on your target age range before writing. Tailor the tone, language, and illustrations to that group.


The mistake: Treating the art as an afterthought or using low-quality illustrations.

Why it matters: In children’s books, visuals are just as important as words—sometimes more.

How to avoid it: Work with a professional illustrator or use a style that matches your story’s tone. Don’t cut corners here.


The mistake: Turning the book into a moral lesson with no fun.

Why it matters: Kids don’t want to be lectured—they want to be entertained.

How to avoid it: Focus on a fun story that happens to include a gentle lesson. Let the message come through naturally.


The mistake: Creating characters with no personality, goals, or emotions.

Why it matters: Kids fall in love with characters, not just plots.

How to avoid it: Give your main character a clear goal, some quirks, and emotions kids can relate to. Make them memorable.


The mistake: Writing in rhyme just because it sounds fun—even if the rhythm is off.

Why it matters: Poor rhymes confuse readers and sound awkward when read aloud.

How to avoid it: Only use rhyme if you understand rhythm and meter well. If not, stick to simple prose.


The mistake: Dumping too much text on each page or placing illustrations randomly.

Why it matters: Poor pacing ruins the flow and can make the book overwhelming.

How to avoid it: Break your story into pages thoughtfully. Use page turns for suspense or surprise, and leave room for the art to breathe.


The mistake: Publishing the first draft.

Why it matters: Even short books need refining.

How to avoid it: Revise, get feedback, and hire a professional editor if possible. Read your story out loud to catch awkward lines.


The mistake: Writing what you want, without checking what kids or parents actually enjoy.

Why it matters: There’s already a sea of children’s books out there—yours needs to stand out.

How to avoid it: Visit bookstores, read popular children’s books in your niche, and see what’s trending. Then put your unique spin on it.


The mistake: Uploading the book to Amazon KDP without checking quality.

Why it matters: A rushed book often looks unprofessional—and poor reviews can follow you.

How to avoid it: Take your time. Double-check your formatting, cover design, and story flow before you hit “publish.”


Writing your first children’s book is a learning experience, and mistakes are part of the journey. But by being aware of the most common pitfalls, you can save yourself time, money, and frustration—and create something that truly connects with kids and their parents.

So slow down, learn the craft, and give your story the care it deserves. You’re not just writing a book—you’re shaping a child’s early reading experience. That’s something truly special.

How to Publish a Children’s Book on Amazon KDP: A Step-by-Step Guide

Publishing your own children’s book is a dream for many writers and illustrators—and with Amazon KDP (Kindle Direct Publishing), it’s easier than ever to bring your story to life and share it with readers worldwide. Whether you’re a writer, illustrator, or both, this step-by-step guide will walk you through how to publish a children’s book on Amazon KDP—without needing a publisher or a huge budget.


A great children’s book begins with a strong story. Consider the age group you’re writing for (e.g., toddlers, early readers, or middle-grade kids), and keep your language and plot age-appropriate. Aim for:

  • Simple language with clear messages
  • Engaging characters that kids can relate to
  • A moral or theme that teaches something valuable

Children’s books rely heavily on visuals. If you’re an illustrator, create bright, expressive artwork. If not, you can hire an illustrator from platforms like:

  • Fiverr
  • Upwork
  • Behance

Make sure your illustrations match the tone and age group of your story. Use a consistent art style throughout the book.


Amazon KDP supports both paperback and Kindle eBook formats. For a children’s picture book, the paperback version usually works best.

Here’s what to focus on:

  • Trim size (popular: 8.5 x 8.5 inches for square books)
  • Bleed settings (especially for full-page illustrations)
  • High-resolution PDF file (300 DPI)
  • Front and back cover (designed as a full wrap)

Tools like Canva, Adobe InDesign, or Book Bolt can help with layout and formatting.
