She is a bit of a natural birth evangelist because she had a quick easy Labour with her first baby.
She said she'd read that there has been a dramatic decrease in premature babies during covid, and this was because women know there is danger in the outside
World so they are holding onto their babies for as long as possible 
I hadn't actually read that stat so I looked it up later and it's true but the possible explanations seem to be to do with women getting more rest and/or fewer infections during lockdowns.
I feel like an idiot that I didn't challenge her at the time. I just hope she doesn't repeat it to women who have had Prem babies.
