1. Know the age group you are writing for.
2. Be honest with children. Make sure you portray feelings. Don’t talk down to children. Don’t preach to them.
3. Let the young hero or heroine solve the problem. Don’t bring Mom or Dad in to solve the crisis.
4. Your protagonist should be a few years older than the market you are writing for. Kids want to be older.
“Children love interesting stories, not commentary, guides, footnotes. Children still believe in God, the family, angels, devils, witches, goblins, logic, clarity, punctuation, and other such obsolete stuff.” Isaac Bashevis Singer.
“We sometimes forget that literature for children differs from literature for adults in degree, but not in kind. Literature for children can and should do the same things for young readers as literature does for adults. Children themselves are different from adults — once again, in degree but not in kind.” A Critical Handbook of Children’s Literature, Rebecca J. Lukens, Miami University Press.
