UPDATE & LINK

My son's home, and doing so well the doc says he can take part in a dance recital today (since he missed his fifth-grade graduation (or "moving on ceremony") and his class play etc.—he's still on antibiotics but the symptoms are almost all gone and he's resting except for the few minutes he's on stage—what a trouper!) He's a tap dancer, just starting, so this is his first show and it's only a short routine.
Meanwhile thank you to everyone who sent their prayers and emails and thoughts and good wishes and comments.
And here's a link to a post by RJ Eskow that isn't anything we haven't heard before, but pretty specific and important.
