What nosotros know is that babies lose their lanugo while they are still in the womb, or shortly thereafter. It falls off into the amniotic fluid. Babies drink that fluid—along with whatever else is floating in it. Afterward the baby takes in the lanugo, it will make its manner through their arrangement and become part of their first poop (meconium).

Information technology'due south thought that the important functions of lanugo include the following:

Skin Protection

In the womb, a thick, white, greasy substance chosen vernix caseosa coats your baby's pare, providing a barrier to protect them from the amniotic fluid that surrounds them in the womb.
