How to make a picture book starring your child

The Once Books team · 22 September 2026 · 6 min read

Making a picture book where your child is the hero comes down to six steps: gather a few photos, build a reusable Avatar, pick a style, write the story, generate the pages, and export the book. The work that actually keeps the child recognisable happens under those steps, and it's the reason a page from the end still looks like the child on page one. Here's each step in order, and where it can go wrong.

Step 1: gather a few clear photos

Start with 3 to 5 photos of one child, faces well lit and looking towards the camera. You don't need a studio shoot. What helps the illustrations most is variety in angle and expression, because that gives the model more of the face to work from.

Blurry, dark, or heavily filtered photos are the most common reason a first Avatar looks a little off. Swap the weakest photo before you generate rather than after. We cover the full checklist in how to choose photos for a book that really looks like your child.

Uploading a photo of your child is a real trust decision, so it's worth knowing what happens to it. Your photos are used to make your book and nothing else, our providers are contractually prohibited from training on them, and you can delete them at any time. The full detail lives on our child safety page.

Step 2: build the Avatar

An Avatar is a reusable character. From your photos we build a Character Sheet, a fixed description of hair, eyes, build and features, and then an Identity Sheet: the same child rendered in a few canonical poses. Those reference images are what every later page draws from, so the face holds instead of drifting.

You approve the Avatar before anything else is made. If it doesn't look like your child yet, regenerate it or add a better photo. Get this right once and it carries the whole book.

Step 3: choose a Style Profile

A Style Profile is the art direction: medium, palette and lighting. You pick one, and it's frozen onto the book so every page shares the same look. Pick the style for the child and the reader, not the trend. A soft watercolour suits a bedtime book; a bold, flat style reads better for a toddler who wants to point at things.

Step 4: write the story

You can write the story yourself, page by page, or start from a template and edit it. Keep it short. A page of a picture book is a sentence or two, and the pictures carry the rest. Decide your page count here: 4 for a tiny first book, 8 for most, 12 when the story needs room.

Step 5: generate the pages

This is where the Avatar earns its keep. Each Scene combines your Avatar, a place and an action, and the engine generates the page from your approved references rather than guessing the child again. A page takes about 25 to 90 seconds.

Not every page lands on the first try. The first take is right roughly 60% of the time, so expect to regenerate some. When a page comes out wrong, you regenerate that page on its own, compare the takes, and keep the one you like. Nothing enters the book until you've approved it, which is the last check against a page that drifted.

Step 6: export the book

Once every page is approved, you open the full book and download a print-ready PDF for $9.99. That's a real file at print resolution, not a screen-only preview, so you can print it yourself or keep it as the digital keepsake. Professionally printed hardcover and premium editions are coming soon, and when they launch you'll be able to order a copy of a book you've already made.

A realistic first book

Do a short one first. Pick your five best photos, build one Avatar, choose a style, and make a 4-page book. That's enough to watch the child hold from the first page to the last before you commit to a longer story. When you're ready, see how the four steps fit together or flip through a finished sample to see the consistency in a real book.

Questions parents ask

How long does it take to make a book?
Each page generates in about 25 to 90 seconds, so an 8-page book is ready in roughly six minutes of generation. Choosing photos and approving pages is the part that takes you the most time, and you set that pace yourself.
How many pages can a book have?
You can make a book of 4, 8 or 12 pages. New books default to 8, which is a comfortable length for a first read-aloud and enough to carry a small story from a beginning to an ending.
Do I need to be able to draw?
No. You upload a few photos and pick a style; the illustrations are generated for you. Your job is choosing the photos, approving each page, and regenerating any that miss.
What do I get at the end, and can I print it?
You get a digital book you can read on any screen and a print-ready PDF you can print yourself, for $9.99. Professionally printed hardcover and premium editions are coming soon.
