Take a writing course that will teach you how to write for toddler-age children. Check for local writing classes or take a writing course online.
Research the different types of published books for toddlers. Young children like books that feature simple stories and everyday activities like getting dressed and bath time. Books that teach the alphabet, numbers, shapes and colors are also popular. Visit your local library or bookstore and study the toddler book section to see what subjects are used and how they are handled.
Begin brainstorming for unique toddler book ideas. Use the clustering technique to tap into your creativity (see Resources). Jot down your ideas in a notebook. Do not worry about constructing a proper story, just let your creative ideas flow.
Write your book for toddlers. Begin stringing the ideas in your notebook together to form a story. As you write, remember tips you have learned in your writing class.
Edit your book. Spend time fixing any mistakes and improving the story. Edit your book on a computer program like Microsoft Office Word.
Have a qualified professional such as an editor or writing teacher read your finished copy to see if they have any suggestions for improvement. Continue to revise your book until you are satisfied with the finished copy.
