We've discovered that smaller packages aren't always inconspicuous. In fact, the most prominent feature of the smallest child in our family is his MOUTH. When he's not astounding us with his vocabulary(belted at the highest volume), or laughing at everything silly(at same volume), or singing nonsense songs, he's eating. At any rate, the Mouth is always open.
p.s. I think that this video from when he was 4-months-old is a good predictor of his future personality. What do you think?
