Wow! I wasn't expecting so many replies so quickly. But it is great to hear! I'm just chilling out on my maternity leave and should probably not be googling things haha. But hey ho.
@Squamata - You're totally right! Because it hasn't been proven, there is no way that the medical team could justify it. But I'm not sure that should be a reason not to consider it personally. I don't see it as having "plenty of risk" though, as it isn't something that would be even considered if I was having a vaginal birth, as no screening occurs. So if it was very likely, pregnant women would be screened for all kinds of infections, not just a select few.
But you are very right that there are lots of other ways to boost my baby's microbiomes. It just seems very confusing how lack of exposure to microbiomes is stated as a risk of c-section, but on the flip side, the medical professionals also say it's not safe to expose the baby. So you're kind of in a catch-22.
I'm inclined to agree with @Vallmo47, that the stated risk is to warn people / put people off a maternal request C/S, but they don't want you trying to find ways to overcome the risks, because they don't really know if there is a causal relationship or not.
@QuiltedHippo - really good point about keeping things in perspective re the antibiotics. Sorry to hear your little one was so unwell!
Really interesting to hear the different personal experiences of @SandysMam, @Yesthatismychildsigh and @ZeroFuchsGiven. Perhaps it all depends on the child and not on the mode of birth at all. It is a minefield trying to work out what is best!
@ZeroFuchsGiven - Sorry your little ones got hurt! Out of interest were the two who got cuts, born via emergency or planned section? It is a risk either way, but I presumed more likely when they are in a rush?
