Congratulations on the birth of your DD. Sorry it was a difficult birth, hope your episiotomy is healing ok. Some hospitals offer a "birth afterthoughts" service whereby you can debrief with a midwife and ask any questions you might have, it's worth considering whether you'd find that helpful.
I recently gave birth to DC2 and it was a much better experience than with DC1. I'll try and keep the stories as brief as possible!
DC1
Went overdue and declined induction, went into labour naturally at 41+4, went to MLU as planned, waters broke while I was there and thick meconium found, transferred to delivery unit as they wanted continuous monitoring, had an unpleasant and unsupportive midwife who did not respect my wish to stay mobile and insisted that I lie on my back on the bed, and as a result I found the experience very stressful and pretty traumatic (as I was in pain and wasn't able to get comfortable), frequent vaginal exams despite the fact that I'd said I wanted minimal exams in my birth preferences notes, ended up with mild shoulder dystocia, which was resolved very promptly and with no injury to baby, but was obviously stressful (I'm 99% sure it happened because I was forced to lie on my back, because it's not an optimum position for opening the pelvis). I had an episiotomy and was in a lot of pain afterwards - couldn't sit at all for several days and after that I sat on a donut cushion for weeks. Had a PPH, not sudden or enough to need a blood transfusion, but gradual heavy blood loss. Also had to have a catheter for about 24h afterwards, which was painful when they inserted it and made me uncomfortable. Lastly I developed a uterine infection (which I'm 99% sure was caused by the frequent vaginal exams after my waters had broken) and had to have antibiotics, first via IV and then tablets after I was discharged. Despite the fact that the birth itself was pretty straightforward, all things considered (no complications from the meconium or the shoulder dystocia) I didn't feel I'd been particularly well looked after and I was in a lot of pain afterwards due to all the things I've listed.
DC2
Was anxious about the birth throughout pregnancy due to experience with DC1. Spoke to birth afterthoughts service (I had called them after DC1 was born but never got a call back 🙄 so had a very belated debrief!) which was mildly helpful. Hired a doula who was incredibly helpful. Wanted two birth partners (husband and doula) but wasn't allowed due to Covid. Hesitated between MLU (first choice but doula wouldn't be allowed) and home birth (wouldn't usually have considered it but doula could be there until midwife arrived). Decided to plan a home birth to keep my options open, figuring I could just go into hospital if I changed my mind, and did end up having a home birth. Baby born at 40+1 and it all happened so fast that I wouldn't have made it into hospital anyway. Completely straightforward vaginal birth, no meconium, no shoulder dystocia, no other complications. Second degree tear which the midwife was able to repair at home, so I didn't have to go into hospital at all
No PPH, no catheter, no infection. So a much much better experience than first time around.
Both my babies were over 9lb btw, first was 9lb4 and second was 9lb1. I've heard that bigger babies can actually be easier to birth for some reason. And statistically second/subsequent labours are usually quicker and easier.
