wait so if these babies are functioning normally as this would imply then how tf do people know the organs are flipped? is this something you can see on the ultrasound in the womb or did they get their babies scanned for some reason? is this a stupid question?? i dont have any kids so im genuinely lost here

edit: i read the article again and “ But, in 2023, the rate jumped to nearly 24 cases per 10,000 ultrasound screenings.” so it was indeed from an ultrasound. my b. leaving this here in case others are confused and stupid like me.
