Just missed my second fast labor in a row yesterday...both 2nd time moms. I have a 3rd second timer coming due any day now. And as second babies are statistically the 'fastest' babies, well, I guess I better hope this mom calls me early and then, I better get on the road ASAP. I only dallied 20min yesterday...only dallied at all cuz mom said "I'm in labor, but I think it'll be awhile, don't come yet". But I thought she was wrong, so I got ready anyway and waited for that second call, which came 20min after the first one.
Anyway, another fast labor to 'prove' that the fast ones--at or near term anyway--are generally the easy ones. The dad called me, clearly in a daze, when I was 12 min from their home. "We have the baby...it's out. What should we do now? Can you hear her, does she sound ok?" (baby yelling lustily in background--a blessed sound for this mw when I've missed one) "Breathe deep...how is Mama?" "uh, K--how are you doing?" (I hear her crowing in background "I'm GREAT!") "she says she's great...what should we do?" "Keep the baby close, comfort her next to mom's skin...I'll be right there. Hey S, Breathe, it's all good!" Dad breathes, and signs off sounding a bit less dazed.....one happy lil fam when I arrive, all is perfect and stays perfect. After a difficult and over managed first birth, Mom is on cloud 9, repeatedly saying things like "I'm a powerful LIONESS!" "I feel so VICTORIOUS"

But something just occurred to me, mwherbs--maybe there is no 'data'/studies on this phenomenon because no one has ever seen any problems with these short labors! No one has yet found a way to make it into something scarey....
I recall in early midwifery training, learning the words 'precipitous delivery', and learning that there MAY be an association with pph and/or baby start-up issues. Something about baby might have issues regarding too fast 2nd stage with too fast of a pressure change from in-yoni to out-of-yoni. Hmmm, potential for cerebral hemorrhage or something of that nature? Never have seen this--tho I have seen a few screamers born fast (more often than I've seen screamers who were born more slowly), but nothing that wasn't soon comforted on mama's belly/breast. No 'precips' who were slow to start, and no pph's. I think this idea of 'danger' in a precip is theoretical, and not at all borne out in reality.
So this discussion, along with my fairly high number of missed 'precips' in the last year, has made me rethink this. Now, I just don't even think I like this term 'precipitous delivery'. It makes it sound like a problem, or a potential problem, when clearly it's NOT. I need to find a new word for these fast mamas, the ones who may have some hours of easy early labor, but with or without that, they have but an hour or 3 or 'hard labor' and quick 2nd stages.
Anyway--again, maybe there is no 'evidence' because only 'problems' get studied--and these Highly Efficient Birthers just don't tend to have problems!
