First Word?

When I was changing Hannah this morning and buttoning up her outfit, I could swear I heard her say her first word. She said "bao" very clear, precise and by itself. Not "bao, bao, bao" or "ba, ba, ba" over and over like her coos and babbles, but "bao" singly and clearly with tones, nothing else afterwards. "Bao" is to hold or hug in Mandarin Chinese. It seemed to be said with the intent to be picked up. She already reaches up with her arms when I reach out to pick her up, and the word seemed to be very clearly said in conjunction with the action. Hmmmm... so far the occurence hasn't been repeated yet. I know, I know... language development takes awhile. But there are things we as adults can do to help them progress and to be aware of delays.
