One of the most important things you need to know about writing for children, is to know what you write. You have to read tons and tons of books written in the genre of children’s literature to really have a good basis for what you are writing for. Once you have an idea for what is out there and how the flow of the industry is moving, then get your ideas down on paper. Don’t be let down if the current books do not match the main concept of your book at that moment, children’s literature changes very quickly.I found some more information here. Any publisher or agent worth their weight in gold is looking for something new and fresh, so your book might be the next bestseller. Another very important thing to do is edit. I know a lot of people don’t like this part of writing, but it is necessary. Sometimes it is just to fix small grammar errors, other times editing allows you see holes in your storyline or problems with the flow. Don’t be afraid to take things out or to change them. The number one thing to remember when writing for children is hang out with the age group you are writing for, that way you understand their level of comprehension. Ultimately, don’t give up, and keep trying as the world needs more stories!
