I don't have any information on children's books. I -do- know that you still do not send art with them. If you're the artist, you submit a portfolio of your work to the art-director. If you're a writer, you submit your writing to the editor (generally through an agent these days). If you're both? Not as sure.

ohiblather used to have links to various writing resources, one of which was for kids, and I think if you follow her LJ stuff back to her blog, there's a sidebar that goes to the writing/freelance related stuff which in turn then opens up to other web-resources <g>.
