I had my back to the living room, taking photos of Ella eating, when she pointed to the front room and said "BUBBA". I glanced behind me and saw a cat and said "oh, is that Titai-kitty?" thinking she was only babbling. She gave me a dirty look, said "BUBBA" and pointed again. Sure enough, I turned fully around to look and it was OBIE she was pointing at. We call him bubba sometimes and I didn't realize her babble was not babble but another word in her vocabulary!
