As an unborn baby grows inside the protective membrane of his or her mother’s amniotic sac, the sac typically bursts on its own, causing the mother’s water to break. The baby you’re about to meet, however, was not born the traditional way — and if you’re able to stomach it, you’re in for a miraculous surprise.

The following footage was recently recorded in a hospital in Spain. It captures the rare moment that a baby is born within a fully intact amniotic sac, just minutes after its twin was delivered normally. This is also known as an “en caul” birth, as the word “caul” means “helmeted head” or “veil.”

En caul births are very rare and are estimated to occur in one in every 80,000 births, possibly even fewer.

Curled up in a ball on the hospital table, the baby can be seen making subtle movements and slight motions, and you can clearly see the blue umbilical cord also inside the sac. Doctors and nurses are gathered around the baby, and it’s clear even they are in awe of the medical miracle laying right in front of their eyes.

I can only imagine what it was like to break the baby out of the sac — and to see the moment the twins meet outside of the womb.
