Sure, your mom says you were cute when you were little, but what she doesn’t mention is that you were a hair-eating zombie with super strength and explosive bodily functions.

#17. In the womb, all babies grow mustaches…that they eat.

pic_001That’s right, you heard me. When a fetus is about four months into pregnancy it develops a mustache that, over the course of a month, spreads over its entire body. This hair is called lanugo and it all falls out before birth (if you’re lucky) and is EATEN BY THE BABY. It then is digested and becomes part of its first poop (called meconium).

#16. Babies double in weight during their first five months of life.

pic_002If you don’t think that’s impressive, just imagine doubling your weight NOW in five months. Babies are basically milk monsters who do nothing but eat, sleep, poop, and grow in freakish amounts. They’re unstoppable.

#15. Babies have tastebuds on the roof, back and sides of their mouth in addition to their tongue.

pic_003They eventually fade with age, but that doesn’t stop it from being really weird in the meantime, especially considering the mustaches they’ve recently eaten.

#14. Girl babies get their period, all babies have boobs and lactate

pic_004When babies are in the womb, they absorb their mom’s hormones, so after they’re born they’ve got some estrogen to sort through. That means that female babies shed their uterine lining, having a mini period, and all babies lactate a bit. Sometimes blood comes out of their nipples too (in case you wanted to cringe even more about this whole ordeal). Horrifying, but true.
