I have found it extremely difficult to decide when a word counts as a first word. I mean, she was saying "dada" months ago. Sometimes it seemed like she was saying it to mean dad, but other times it seemed like she just said it. She just recently started imitating our speech. She would say the word after us, and eventually started just saying it to herself over and over. But there was a breakthrough yesterday. She said her word in response to an appropriate event twice. Therefore, I'm counting it as her first word. The word is "uh oh." Hey! That's two first words!
