I think I can stop holding my breath and finally announce out loud that Clara may just be mostly potty-trained!
July 6th, I wrote on the calendar, "Clara went pipi on the potty!" It hadn't happened for a few weeks, so worth documenting. Then she did it again the next day. And the next. And even some times in those days she'd feel the urge, run to the potty, and sit there before realizing it was a false alarm.

But she knew what was going on.
The last couple of days, she's even gone poo in the potty, so I think we're really onto something. And now she'll go two or even three times a day (although wetting the diapers while sleeping seems to be an automatic reflex . . . I get it). But she generally runs around naked all day and hasn't had an accident for . . . I can't remember how long!
Of course, I realize that she's likely to take a BIG backslide in the next week/month, given the imminent upheaval in our lives. However, since she's come this far, I'm sure she'll hop back on that horse, once she's OK with relinquishing her spot as "the baby" (I'm just hoping that won't take the better part of the rest of this year).
I am really nervous to take her any farther than the butcher's across the street without diapers on. But, these days, we don't go much farther than the butcher's, so it's really not an issue.
But, for experienced parents out there, when do you know that she's ready to go out in public without diapers? (Like, long enough for a drive to the grocery store?) I have a feeling that Clara is pretty far from that point, but maybe I'm just being too cautious.
