Do babies eat their downy hair in the womb?

Yes, babies can ingest their downy hair, known as lanugo, while in the womb. Lanugo is a fine, soft hair that covers the fetus and is typically shed before birth. Ingesting this hair, along with other substances, can contribute to the formation of meconium, the baby's first stool. However, this practice is normal and does not pose any harm to the developing fetus.
