This is the incredible moment a baby girl is born still inside an intact amniotic sac, which she then breaks with her tiny hand.

Mum Rosangela Maria Sousa Soares described the event at the maternity hospital in the city of Goiania in the Brazilian state of Goias as a “magic moment”.

Rosangela, who hails from the town of Crixas, also in Goias State, gave birth to identical twins Isis and Elis.

Isis came out first, followed by Elis, who was born still inside an intact amniotic sac, which she was then filmed breaking with her tiny hand.

The healthy girls were born at 36 weeks on 26th November weighing 2.2 kilogrammes (4 lbs 14 oz) and 2.3 kilogrammes (5 lbs 1 oz) respectively.

The newborns did not require incubation, and both mum and daughters were able to return home two days after the birth.

Rosangela is married and the couple has 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 – occurring 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 when the baby is about to be born.
