Holding a sick child at 3am, whose little body is racked with a fever you've done all you know to do for, is frightening. You can read about how this is normal, and hear from folks whose kids have gone through it, but it's still scary.
Thank you to both moms (sometimes even a mom needs reassurance from her mommy) and our pediatrician for their words of comfort; my son is doing much better today.
Currently 104° and sunny. Very, very sunny.
