Oromorph is lovely. But it also constipates, so stop it ASAP. I had 2 doses with my first CS, 1 with my 2nd and none with my 3rd.
Stitches: different surgeons do different things. My first 2 I had a continuous stitch which was removed on day 5. Fine and very comfortable, though it did open back up a little after a week or so. They healed fine. With my 3rd I had dissolving stitches. The scar did not open up, but the stitches took weeks to go away and were very irritating. I had far more discomfort (including pain coughing etc) for a good couple of months. I'd take the wound opening a little over that!
After the op you'll be in bed with a catheter, sat on a disposable pad with a sanitary towel between your legs. And no knickers because of the catheter. You will also have support socks on. Don't get out of bed without help. You'll be very wobbly, and I had a lot of blood that just fell out all over the floor and the socks (white) after my first.
Removal of the placenta triggers milk production. This is the same with a vaginal birth. So BF no mother likely to be a problem. In fact, a nice calm elcs might make it easier than a long traumatic VB...
CS babies who have not experienced labour have not been squeezed by your contractions so are at increased risk of respiratory distress. The delivery team will know this and help if required. My 2nd had this: he had to wear a breathing mask for 12 hours and was in nicu. He has been fine ever since.
It might be possible to 1. See the birth 2. Chose your music 3. Have the lights dimmed 4. Have baby put straight on to your chest. Ask. You / DP might not be allowed to cut the cord though due to sterile conditions.
My first (emergency) and 3rd sections were wonderful, magic calm experiences. The second one not so much. A combination of a bitch anaesthetist and a prem / sick baby. Unlucky really. Actually more the anaesthetist, as the prem baby was anticipated.
