Doctors at Queen Charlotte's hospital in London are pioneering "natural caesarean" births with the aim of making the surgery less traumatic for mother and baby.
Normally, after the incision, babies are delivered rapidly behind a screen. But in this case the parents, Sheri and Jason Tan, are able to watch the baby's head emerge.
A full minute later the baby is still only half way out and only now decides to wake up and announces its presence.
It takes three minutes for the baby - a boy - to be delivered - and he's immediately passed to his mother.
The aim has been to make this invasive form of delivery as un-traumatic as possible for mother and baby Evan.
Queen Charlotte's says the natural caesarean is now becoming an established procedure at the hospital.
