How Do I Write a Good Story Prompt?

What is a Story Prompt?

Your story prompt is the short description you write to tell Lullaby what kind of adventure to create. The prompt is the most important input — it shapes the plot, setting, and tone of your child's story.

How to Write a Good Prompt

A great prompt includes three things:

  1. Something about the child — their interests, personality, or a real-life situation.
  2. The adventure — what happens in the story.
  3. The setting or theme — where and when it takes place.

Example Prompts

  • "Emma loves dinosaurs and is nervous about her first sleepover. She discovers a friendly baby T-Rex who helps her feel brave."
  • "Ben is obsessed with space. He builds a rocket in the backyard and visits the moon, where he meets a family of space rabbits."
  • "Maya loves baking with her grandma. They bake a magical cake that brings the whole neighborhood together."

What to Avoid

  • Prompts that are too short — "A story about Emma" doesn't give enough detail.
  • Violent or scary themes — Lullaby creates age-appropriate stories for children ages 1-12.
  • Too many plot points — Keep it to one main adventure. The AI works best with a focused story.

Include real details from your child's life — their favorite toy, their pet's name, or a place they love. These personal touches make the story truly special.

Prompt Length

Aim for 2-4 sentences. This gives enough detail for a rich story without overwhelming the AI. The minimum is 10 characters and the maximum is 2,000 characters.
