If you are interested in writing for children, I suggest joining the Society of Children’s Book Writers and Illustrators. (www.scbwi.com)
If you have a story you are ready to send to publishers, Children’s Writer’s and Illustrator’s Market is a good place to start. The guide includes contact information for book publishers, magazines and agents.
