Well, all back labor isn't created equal. There's feeling contractions in your back and then there's feeling like your back IS BEING RIPPED APART. Neither is fun, but one extreme is definitely do-able longer than the other!
Hmm, positive things?
Discovering that dh is a fantastic labor partner--he kept his mouth SHUT (except when I needed talking) and didn't project worry at all.
Dh announcing the gender by saying "here's Lina, dear."
How calm Lina was when I first saw her, that part was actually just as I had pictured it being.
And I daresay that in a year or so I'll be able to look back at those first exciting moments of "I think this might be real labor!" without dredging up what came afterwards.
