First Word?

Brendan might be saying his first word...it's hard to tell if he's just yelling or if he's actually saying "Hi!" It seems to come out a lot like "eye" and he usually yells it at the top of his lungs. He does seem to do it at somewhat appropriate times...in Kroger as other people are nearby...so I guess we'll see! At least if it is his first word, it's a neutral one...not mama or dada.
