Hiya, do not feel guilty or disappointed about having a cs. my ds was breech and failed to turn after ecv so I had a planned cs. It was really fantastic, so calm. DH and I got up really early in the morning and sat up talking, watching the sun come up and generally getting excited. Went to the hospital about 9am.
Was booked in and sitting in the waiting room for a while as there were two emergency cs' ahead of me, so dh and I got all giggly and excited and took loads of photos of each other in our surgical gowns! I then walked in to theatre with dh, had all my lines put in and the spinal block (I was a bit shaky for that, but it was done in about 5 minutes) they then started the cs and ds was born about 5 minutes later.
One thing I really regretted and I would strongly urge you to do (unless you're really squeamish) is have the screen lowered as your baby is being born. I really regretted not seeing ds as he came out. I was really worried I'd see my internal organs and be completely grossed out, but in reality you do have a big bump in the way, and the incision is so low there's no chance of you seeing anything.
I would also insist on having your baby handed to you as soon as they've done whatever they need to do (the baby may need a bit of suctioning to help him/her breath - totally normal for cs babies). My ds was handed to me cleaned up with nappy on and dressed and I never got to hold him naked skin to skin which I now really regret. I think I was so bowled away with the whole experience I completely forgot to ask!
After ds was given to me he never once left my arms, he was latched on in recovery and feeding well, and my milk came in two days later which is pretty good considering people often have a delay in their milk coming in if they have a cs.
I recovered really quickly from the cs, was on my feet the next morning after the catheter was out and had a shower. By day two I had no pain and didn't bother with any pain meds, I was sent home on day 3. I did have two baths a day on the recommendation of my mw and put a few drops of lavender oil and tea tree oil in to help healing. Don't know if it works but it smells lovely. I felt 100% after about a week although I did take it easy for about four weeks. I was driving again after about three weeks.
In terms of preparation, I don't think there's much you really need to do, getting a freezer full of food is a good one but I would have done that anyway with a newborn. Buy some high waisted knickers that'll sit over the top of your scar. Some people suggested taking arnica, but I totally forgot once ds was born to take any more, I did take some before the cs but nothing afterwards and I had no bruising and healed very quickly.
I hope everything goes well, if the baby doesn't turn don't worry about a cs, it's really not as bad as you think. I was very grateful for a couple of extra days in hospital too, I know some hate it, but I was a nervous first time mother and I really appreciated having midwives and health visitors around me all the time so I could bombard them with questions! Good luck!
