A video uploaded to Facebook under the name Jasmine Perez captures the precious moment a baby born still inside its amniotic sac finally emerges and takes its first breath.

As you may already know, the amniotic sac is the bag of fluid inside the womb that serves as the fetus’ home while it develops.

An expecting mother’s “water breaking” indicates the amniotic sac has broken. If the mother opts for a C-section, then the surgeon delivering the newborn would cut through the amniotic sac. “En caul” births, on the other hand, is when the infant is born inside of an unbroken amniotic sac and has to be surgically removed. These types of births are rare — occurring in fewer than 1 in 80,000 births — and are generally considered harmless.
