Question: baby has a lot of hair?
Answer: “It'll be gone before you know it.” That soft, downy hair is called lanugo (pronounced “la-NOO-go”). It's produced by fetal hair follicles during the second trimester and keeps a baby warm inside the womb. Many babies lose their lanugo in utero (around 32 to 36 weeks), where it's shed into the amniotic fluid.
