Our son was reading Where the Wild Things Are, and kept adding words here and there to the sentences. They were just filler words like "the" and "that", but it got me thinking that maybe he wasn't really reading as much as reciting sentences that he's more or less memorized.

I started to gently correct him when he added the words, but he started to get frustrated - both because reading is hard but also because I kept correcting him. Eventually we got him using a pointer (i.e. a chopstick) like he's supposed to, to point to each word as he read it, and that seemed to help. Still though, he added some filler words here and there.

Should I be correcting him if he adds words, if it doesn't change the meaning of the sentence? Or should I be focused on mostly positive reinforcement and trying to get him to love reading?
