As a side note, getting cut off in traffic is even more annoying when you have a screaming baby in the car

Babycenter.com's weekly email tells me:
"Now that your baby's awake for longer periods during the day, you can use these times to support his sensory development. Try singing your favorite lullabies or playing music.

"You don't have limit yourself to children's songs. Fill the house with the sounds of music — from the Black Eyed Peas to Mozart — and watch as your baby expresses his pleasure through coos, lip smacks, and jerking arm and leg movements.

"Inevitably, you'll notice that your baby responds to and favors some selections more than others as he begins to develop preferences."

I am happy to report that Gwen's musical tastes are developing nicely. Today we were out in the car doing errands and Gwen was fussy (she is, sadly, not one of those babies who just drifts off to sleep anytime she's in a moving vehicle). Fuss, fuss, cry, cry. Then my big giant CD of random music started playing "Your Own Personal Jesus" by Depeche Mode. She stopped crying. "Hmm," I thought. "It appears the girl has good taste."

The next few tracks, all Depeche Mode songs, were uninterrupted by Gwen's fussing/crying/screaming. But it could just be a coincidence. Then the Depeche Mode selections ended and a Feist song came on. I don't know how she did this, but before the song even got past the instrumental intro, she started fussing again. I quickly skipped back a few tracks to "Policy of Truth" and she was immediately quiet.

I couldn't be more delighted!
