Can You Say No???

My little pooh bear is really starting to say some real words.  He has had a handful that he has said for awhile now like touchdown, kitty, Tonka, Daddy and of course Paige whom he calls "G" (yes, I realize Mommy is sadly not on that list).  Lately I have noticed his words are getting more refined and he gets not only excited to use them but excited that we understand.  The latest is "Hi!".  He says it as soon as he sees me walk into a room or in the door after work, or in after taking out the trash or when he comes into a room.  I caught him the other night willing to demonstrate how he uses another favorite word, "No!" which is of course pretty cute to see.  Cute for now anyway because in no time I won't appreciate this word quite so much.
