Jenafur,
What kinds of books do you read to him? Does he like books on tape?
I remember feeling like quite an oddball readidng "Phantom tollbooth" "Ozma of Oz" and "Wrinkle in time" to a 3 year old. I also thought it was weird that other parents actually read "Magic Tree House" books to their children! ACS I am jealous!
Do you have any special favorite books from childhood? If so, try 'em.
As far as "what age they can handle sentences" - I guess when they are ready they will. You may want to have his "vision function" tested - but it may be part of his normal physical development.
I would also encourage him to "read" picture books what are wordless - there are some beautiful ones out there.
My Mom's custom is books on the Computer for each Grandchild when the reach the "word reccognition" phase like yours has.
Love and More Love,
Trinity
