First Word?

So I really think Lena said her first word last night. She's been babbling for a while now. Mostly, it's ba-ba-ma-ba-ba-blah-blah, etc. But last night, I laid her down on the changing table, and she slowly and clearly said "ma-ma". It was awesome! Of course, I was the only one who heard it. Now she's moved on to "la-la-la-la". Hopefully, it will be be "da-da" soon.
