That would have been so much easier.

That's why I'm really glad that you're reading this one out.

I had to Google it when I was looking at this.

So it's not like a sort of staggered start.

Everyone's going to have a go.

I don't have nothing to say.

I think it's growing in how common it is.

So I think there are kind of clinical indications as to why you might get it if your baby has been transverse or breech or suspected to be in the third trimester.

That's an indication to have it done to see, check that the baby's the right way around as you approach your birth planning.

And then obviously another reason to scan would be if the measurements of the baby suggest that perhaps

it's either too big or bigger than you might expect at that stage or smaller than you might expect at that stage.

So not routinely.

Yeah, but this would just be saying everyone, no matter what, has this.

And it's interesting because it's not really like you're trying to detect a specific thing.

This is why I was stunned into silence because I was trying to imagine what it was that you were trying to find with this third trimester scan.

Is it like...

A few babies that were the wrong way round.

Is it a few babies that might be too big or too small or polyhydramnios?

So I guess it was.

Yeah, I was trying to think through what it was about.
