Thanks, skyward. I'm just starting to think this might be what's wrong, so I really appreciate the links. I'm not even sure who to ask about it or what to do yet.

And maybe it's nothing. Reversals and mirror images aren't exactly uncommon at this age. I could be making much ado about nothing. But I'm pretty well convinced that I'd rather be "that mom" and find out that it's nothing than to go with the flow and find out later that it was, indeed, something.
