Note — video has no sound: A study at a British University using high resolution ultrasound has confirmed with fascinating evidence behind the belief that unborn babies yawn incessantly as they await birth. A writer at the BBC said hanging around in the limbo of the womb seems to be so dull it is little wonder that foetuses yawn. This video shows it for the first time. But it may not be because they are bored. The most likely explanation is that foetal yawning is an essential process linked to brain development. While it is well known that foetuses open and close their mouths, experts had disagreed over whether or not they were actually yawning. But this study carried out at Durham University, using high resolution ultrasound footage, has confirmed that babies really do yawn, and do it often.
