Brainstorm ideas. Think about what you want to convey in your story. Contemplate the theme or message you want to focus on and commit to it.
You can write about a serious topic like divorce, cancer or death and explain constructive approaches on how kids can handle the situation. If you choose a lighter subject such as birthday parties, first day of school or sports-related stories, remember to keep the overall message positive.
Create Characters. Your characters are what drive the story. They are one of the most important elements of the storybook. Create memorable and unique characters that kids can relate to and whose quest captures their interest.
Develop a storyline. Ensure that there is a conflict or problem that the main character must solve. Keep it simple, yet challenging enough to engage the reader.
Make sure you focus on your protagonist and what he does to overcome his problem. Reveal his personality and character mostly through actions, and less through dialogue. Remember that storybooks are a visual medium and the pictures are just as important as the words.
Developing your antagonist is just as critical to the story as the protagonist. Be sure you know what the character will do throughout the book and at the end before you begin writing.
Prepare an outline. Storyboard your idea so that you sharpen your visual thinking. Include a vision of what you think the illustrations should resemble. This step helps layout the structure for your story, so if there's a point in the sequence that doesn't work, you can rearrange it.
Write your first draft. Keep in mind who your audience is, and write appropriately for that age level.Avoid complex, compound sentences and long narratives. Authors like Dr. Seuss sometimes use literary devices, such as rhyme or repetition to establish a style.
Edit your story. Review your first draft for any errors. Give it to people whose opinion you value and ask them to proofread it for you.
Rewrite. Take into consideration any edits or suggestions you may have received and incorporate them in your next draft.
