The magical moment a tiny infant who was born inside her unbroken amniotic sac breaks free by punching out with her little hand has been caught on camera.
Mum Rosangela Maria Sousa Soares was giving birth to her identical twin girls Isis and Elis at the maternity hospital in the city of Goiania, Brazil.
Little Isisi was born first, closely followed by Elis, who was born unusually with the amniotic sac still intact.
Rosanglea described the moment Elis stretched out and broke free through the sac as "magical".
The healthy girls were both born at 36 weeks on Friday, November 26.
They weighed 2.2 kgs (4lbs 14oz) and 2.3 kgs (5lbs 1oz) respectively.
The newborns did not require incubation, and both mum and daughters were able to return home two days after the birth.
Married Rosangela two other children - a daughter, who is the eldest child, and a son.
'En caul' births, where the baby is born still inside an intact amniotic sac, are rare.
They occur in less than one in 80,000 births, according to a 'Case Reports in Obstetrics and Gynecology' study.
En caul births are not considered to be risky to either the mother or the baby.
In most births, the amniotic sac, which is filled with amniotic fluid - a light yellow liquid that protects the baby and keeps it warm - breaks during the early stages of labour.
