Cora has been saying some repeated and single syllable words for a while now: Mama, Dada, Buh or Buhbuh (for Bucky), Chee (cheese or cheek), eye, hi, yeah, ball, etc. And she has perfected a number of animal noises which I don't think count as words even though they are sometimes uncannily accurate.
But last night she made a major shift in speech development. We were finishing up her bath, and I said "time to say goodbye to the water". A couple minutes later, Cora says "Byebye wawa!" Officially a two-word phrase! And then we were reading an ABC book and she said "apple tree", and was so proud of her ability to say apple that she kept saying it over and over again. It is always funny to me that I am so surprised when she starts doing something new like this, even though it is obviously just a normal part of development. But really, since when does our little baby say multi-syllabic words?! I guess since yesterday. It is such a joy to watch her communicate.
