New words

Here is a list of words that Grant can say (with proper meaning most of the time):

Hi (Grant's first word was the same as Leah's)
Doggy (this word can mean almost any animal too, and most things)
Kitty (he says it "kiggy")
Daddy
Bath (more like a whispered "bahhh")
Uh-oh
GO-GO-GO (spoken whenever he sees a sports game on TV, or during the opening song of The Cat in the Hat)
Peekaboo ("pee-uh-oo")
Apple ("appo" or "appu")
All gone ("ah-gin", but you can tell what it means because he says it whenever something is all gone!)
Eye

And a lot of grunts and pointing fill in the rest.  It's amazing what you can understand from a grunt, a tone of voice, a point, and a specific facial expression!
