Video: Baby Born Encased in Amniotic Sac After Twin Was Born Normally

This is the moment a Spanish child was born while still inside its fully intact amniotic sac - known as the caul - something estimated to occur in one in every 80,000 births.

Over the weekend, this baby was born with the membrane covering its entire body, just minutes after its twin was delivered normally!

Normally, the amniotic sac is broken during the strenuous process of childbirth or is pierced with a scalpel during a caesarean.

But not this little cutie!

Check out the phenomenal footage above.
