Hi OP. My first baby was estimated at 9lb 5 at his last scan. By then I was 10 days overdue. I did not want to be induced, so had a bit of a wobbler and asked for a c section. They did it the next day. He was actually 10lb 5 so it was a good call.
I see a lot of people say giving birth to a big baby isn't necessarily much worse. But for me personally, having been told for months "aren't you measuring big" did nothing for my confidence and I went into it thinking "I can't do this". I do believe a lot of it is to do with positive mental attitude and all that mamarkey, but then there are factors like a breach birth that all the positivity in the world can't put right.
I knew I wanted a c section long before my baby started measuring big. I would have been very happy to not be there for the birth at all to be honest! I'm not very brave at all.
I found my first c section surprisingly calm and relaxed - not what I was expecting at all. In fact, it went so well I went back for another last Friday 😊 Baby was measuring big again this time too - off the charts in fact - but she was 9lb 1. Just goes to show they can be smaller as well as bigger.
As for the covid stuff, my partner was allowed to stay with me while I waited to go into theatre, for the operation itself, and for 3 hours afterwards since we had a side room in which to recover. Again, it was all very calm and relaxed - not that much different than the first to be honest. He did have to leave when we went down to they maternity ward at 1.30pm. I thought it would be awful but it wasn't at all. You have a buzzer and the nurses helped me so much. I think I actually got more sleep this time as I didn't feel guilty about DP having to sit in a chair all night. Then I was out by 10.30am.
If you want a c section, push for it. I found once I got past the midwives, the consultant was very amenable. My 2nd pregnancy was consultant led and at the initial meeting he just asked me to what my preference was - that was it.
Wish you all the best OP.
