You really ought to read this absolutely fascinating article in the New York Times a few weeks ago about babies, brains, and inborn traits for anxiety and worry. Of course, as a psychologist, this research does not surprise me at all. But it's nice to see scientific validation for how you know you (and your firstborn daughter) were just made, no more alterable than the color of your eyes or the shape of your face.
