context_page_description: A caul or cowl is a piece of membrane that can cover a newborn's head and face. Birth with a caul is rare, occurring in fewer than 1 in 80,000 births. The caul is harmless and is immediately removed by the physician or midwife upon delivery of the child.
  The "en-caul" birth, not to be confused with the "caul" birth, occurs when the infant is born inside the entire amniotic sac. The sac balloons out at birth, with the amniotic fluid and child remaining inside the unbroken or partially broken membrane.
context_section_description: A child "born with the caul" has a portion of a birth membrane remaining on the head. There are two types of caul membranes, and there are four ways such cauls can appear.
  The most common caul type is a piece of the thin, translucent inner lining of the amnion which breaks away and forms tightly against the head during the birthing process.  Such a caul typically clings to the head and face, but on rarer occasions drapes over the head and partly down the torso.  In Germany, this would be called a "helmet" (Galea) for boys; in the Netherlands it is also called a "helmet", both for boys and girls (Helm) and in Italy a "fillet" (vitta) or "shirt" (camicia). In Poland, it is called a "bonnet" (czepek), for both sexes.
