No, no Luke

This morning was a small milestone for Luke.  He did something that required correction and I think he actually knew what I was saying.  I usually have his exer-saucer by the window in the den so he can look out the window if he wants.  Today he started grabbing on the blinds for the first time...  when I said (in a sweet voice of course) "No, no Luke" he looked at me and grabbed again.  That little stinker...
