Sorry, false alarm. No baby.
The doc did say he expected him to come sometime this week, though, so stay tuned.
Update (05/02/06 7:48 AM CT)
After I posted the false alarm, the contractions started again. We got to about 7 minutes apart, and I told Frank & Carla online we were on our way. But the contractions slowed down, and finally stopped about 1 AM or thereabouts, so no baby yet.
