I think that "aaarooh?" is officially Eisley's first word. She grabs the phone out of my hand, holds it to her ear and says, "aaarooh?" And if there's not a phone close, that is ok, a shoe will work just fine. And if there's not a shoe close, then her hand will also do. Just as long as it's up against her little ear, she will say "aaarooh" into it. For those of you who haven't yet figured out what "aarooh" means, it is "hello" :).
Sure, Eisley will say "dada" if as prodded and mimics other words like "all done" which sounds like "aaahdaa" but "aarooh" is the only word she seems to say on her own with in the appropriate context.
