9 Health Facts About Newborn Babies

1. Salt is tasteless to them


Babies are born with a well-developed sense of taste, but not for salt. Studies show that babies can't taste salt until they are four months old. They can taste other flavours as well as adults can, especially sweet, bitter, and sour flavors.

2. They cry ... but don't shed tears


Newborns cry so much they make you tired, but they don't shed tears, thats because their tear ducts aren't functional until they're between three and twelve weeks old. (They can, however, produce "basal tears," the non emotional tears we produce constantly to keep our eyes from being dry.)

3. They have no kneecaps


Waoh! If you X-ray a baby's legs, you likely won't see anything where the kneecaps should be, and if you do, it'll just be small, smudgy spots. That's because all bones begin as cartilage, and they harden, or ossify, over time. Kneecaps take a long time to form (from three to five years) and because cartilage doesn’t show up on X-rays, babies appear to have no kneecaps. In all this is a good thing, because the spongy tissue serves to absorb some of the shock toddlers take during their crawling months and from their constant falls.

4.They have more bones than adults do


This is funny considering how small they are, but they do have more bones.
Way more: about 300, compared to an adult 206. The reason is related to why they lack real kneecaps: some of a baby's separate bones join together into single bones as they ossify in the months and years after birth. For instance, the skull starts off as many separate bones that fuse together into one large bone by about the age of two.

5. They menstruate


This one got my mouth open. Well, while still in the womb, babies are exposed to high levels of the female hormone estrogen. At birth, when the baby is removed from the womb, as it were, those estrogen levels fall rapidly and in girls can cause what is known as pseudomenstruation, similar to menstruation in young and adult women. (Sharp drops in estrogen and related hormones are in fact what triggers menstruation in adult women.) Mothers unaware of this often get scared, when they see a little blood in their babies' diapers, but it's very common and happens in about a quarter of all female babies, usually in the first seven days of life.

6. They lactate


The reduction in hormone levels that causes psueudomenstruation can also cause galactorrhea, an occurence in which newborns develop tiny breast buds, and actually lactate, producing tiny amounts of milk from their nipples. It can happen to both boys and girls. Like pseudomenstruation, it's not dangerous or uncommon, occurring in about 5 percent of all newborns, and can persist for up to two months.

7. They've drunk their own pee
Eeew!


Babies start to urinate in the womb just a few months after conception. Where does it go? They drink it! This is how it happens, the urine mixes with the amniotic fluid surrounding the baby in the uterus. And by the third trimester of pregnancy, a fetus swallows about a liter of amniotic fluid every day. Since a fetus does not need hydration or nutrition in the womb (that comes from mom via the umbilical cord). This means that each and every adult has spent several months of our lives drinking our own pee.

8. They do remember what they have tasted in the womb


As earlier discussed, newborn babies cannot taste salt, but they can taste other flavours, and they can taste those flavors while they're still in the womb, starting from about four or five months into pregnancy. Amniotic fluid is known to be affected by the food eaten by the expectant mother which, in turn, affects a baby's choice of flavour after birth. If a pregnant mom eats a lot of garlicky foods, for example, the baby will taste that in her amniotic fluid in the womb, and will have a good chance of being drawn to garlic-flavored foods after birth. Intresting huh.

9. They're hairy


Babies are born with just a few tufts of hair on the top of their heads. This isn't what we're talking about. As it develops in the womb, a baby's entire body becomes covered in a thin layer of hair called lanugo. This hair helps regulate a body temperature in the womb. So, if your baby is born looking like so hairy, don't worry: it's just normal. The hair will fall out on its own over the first few weeks of the newborn's life. If your baby wasn't born covered in lanugo, well, it already fell off toward the end of gestation.
