Caul

A caul is a membrane that sometimes covers the head of a baby when it is born. It is a piece of amniotic sac and can be thin and veil-like or thicker and more substantial. The presence of a caul is a rare occurrence, with estimates suggesting it happens in roughly 1 in 80,000 births.

Historically, the caul has been associated with various myths, legends, and superstitions across different cultures. In some traditions, it was believed to be a sign of good fortune, protection, or special destiny for the child. It was sometimes kept and preserved as a talisman. Conversely, in other folklore, it was viewed with apprehension, though this was less common than the positive associations.

Medically, the caul has no inherent significance regarding the health or development of the baby. It is simply a remnant of the fetal membranes. If present, it is usually easily removed by the healthcare provider shortly after birth. There are no known risks or complications associated with a baby being born with a caul. The term is derived from the Latin word "colare," meaning "to strain," referring to the membrane's appearance.
