Zander's first words

So Zander just recently said his first word. No it was not mom or dad or anything cute like that but his first word is Dog. He loves our Cleo dog and I can always get him to stop crying or being a pill by asking him, "where is Cleo?". So shock of shocks when in the last few days he started saying his second word. Any guesses? Of all the words out there he can now say Cleo.
