Hi - there is a company called seedlings - http://www.seedlings.org/ - that brailles books for kids. There are links to other blindness related resources as well! They are great!
Also, if any of you are looking for specifically Christian books, I work for a great library called the Assemblies of God Center for the Blind. You can get books to read to your kids and books for yourself, too! (417)831-1964 or blind@ag.org
