Heather's been having contractions, so we're going to the hospital (doctor's orders, and welcome at that). While not catastrophically early, it is worrying as Louis is not quite 34 weeks along.
[Update, 10:30pm: We're back. Everything's OK, though we have to follow up with the ob/gyn on Wednesday. It may have been dehydration, but there were no signs that it was labor. Cervix is intact, no dilation, and The Boy 2.0™ is, according to all signs, just fine. Thanks for the prayers.]
