Modify your "reading" to whatever level your child is ready for. It may not mean reading the words of the book at all, but just turning the pages of a board book as you say "turn, turn, turn... all done!" Even skip some pages to make him successful but try to keep him a little longer each time, if you can! Sometimes it is a challenge to get kids to look at books so we don't want to expect too much at first, such as really reading all of the words/story to them. I always try to make any activity (reading, bubbles, blocks,...) as simple, fun and interactive as possible so they will want to stay in the interaction. The sillier, the better!
HTH!
