How do you write a children's story?

Answer 1

You write a children's story in the same way you write any story. Use vivid description. Create believable characters which will catch the reader's interest. Show action; don't tell boring text.

One thing you need to keep in mind for a children's story that you might not think of in adult writing is the reading level. You will need to use simpler terms and shorter sentences for children. Other than that, the basic principles are the same.
Make it simple with no long or difficult to understand words.
