@daphne1 This is all just my understanding/ recollection from my own research on the subjects, though I don't have the studies/references on hand.
a. PROM (but contractions started pretty soon after).
Slight increase in chance of PROM above the average (avg is 8-10%), so not even close to guaranteed.
b. “Active labor”-type contractions (lasting about a minute, happening every 2-3 minutes) from the beginning, so for about 23 hours. I think this can happen with PROM, but I'm not sure if it happens every time.
I had similar and was informed it's actually fairly common, but yes, if you had this
c. Unsatisfactory progress during labor, necessitating augmentation with pitocin. (I needed a lot of pitocin, and at this point, I got an epidural, which may influence some of the other things.)
Again, it's not uncommon, but I believe this is less common in subsequent labor, as your body gets "better" at it.
d. Extended pushing - pushed for nearly four hours.
Same as above.
Yes, I believe tearing is more common in subsequent births. But not guaranteed.
f. Prolapse of bladder and urethra.
Same as above.
g. “True” low supply when breastfeeding (tried literally everything to increase supply, under the care of IBCLC and doctors, over the course of 6 months, and still never had a full supply).
From my discussions with my LC, true low supply is usually caused by insufficient glandular tissue (nothing to do with breast size, small breasts can have enough glandular tissue, large breasts can have not enough). And glandular tissue can not be increased. I would recommend planning to combo feed or do formula only for your own mental health.
h. PPD and, I think, PTSD (from threatened forceps during pushing). Subsequent lack of bonding with baby (still not really dealt with).
Yes, having PPD once means more likely to have PPD for subsequent pregnancies, but not guaranteed. There are lots of influencing factors into the severity of PPD such as sleep, support, and baby temperament (and I'm sure the PTSD and supply issues didn't help).
So somethings are likely to be better, some the same, and some worse, purely on a dice roll. But you really never know.
Personally, I had a bad labor, and it was likely to have similar issues the 2nd time, so I opted for a scheduled csection.
I also had PPD with our 1st (who also had colic) and made sure we had extra support for our 2nd (who is much more chill). For the most part, my PPD was less to start with as we had extra support. Then that support left, and my husband went back to work, and my PPD got worse than with my 1st. Then, we got more support and rented a snoo, and it got better again much quicker.
