Reading with Kids

I love reading to my children. Last Christmas I read A Christmas Carol to my 6-year-old at his request. He is now the only child I know that will hang a jump rope around his shoulders and say he is the ghost of Jacob Marley. But he is having the hardest time learning to read on his own. We go over and over sight words and get simple books from the library. Things just don't seem to click for him. Maybe I have spoiled him, but I want him to love books as much as I do. I guess we will just have to keep working at it.
