Every unborn baby grows a moustache in the womb, which then spreads to cover the entire body. The baby then eats this fine hair, called lanugo, and excretes it after birth with their first bowel movement, which is a substance called menocium
[A/n : me after reading this : TF!?? I never knew I ate a freak-ton of hair before I was born 😫😖]
