I'm often surprised how long this take will keep his attention.
In other news he said his first recognizable words the other day: "all done!" This with his hands in the air at the end of the meal was to indicate that he was finished eating. He definitely has the sense of the words themselves though, since he has started saying them at the end of a prayer in place of "amen" or when he's done playing with a toy, etc.
What was it that I felt at first hearing his infant voice? I felt full, amazed, awe-struck, happy, proud...And now it seems that I am to daily discover new things he can do, understand and enjoy. I love this part!
