Cooper has started to understand humor.  While Nana was visiting he loved saying her name very fast when riding in the car and then giggling when she said his name back.  He has also started going limp when you try to take him out of his crib landing on his belly so he gets back rubs.  He thinks he is hilarious and we know he got his love of back rubs from his Daddy, I just didn’t think it would start at such a young age.
