Well, not really. But sort of.
Not only does James say "Dada!" when he sees Eliot, tonight I realized that he had added another word to his repetoire. When he was finished eating his dinner, he started saying, "Ah-da, ah-da!" which, I now know, means ALL DONE! We've been saying it over and over again and signing it for months now (he has signed it up to this point by shaking his hands when he was finished), but now he SAYS something that MEANS something. Progress!
And, I should mention that when I said "woof woof" today while making a dog shadow puppet, he immediately patted his leg... the sign for DOG!
That's it, it's official. My kid is a genius. :-)
