Amazing Facts About Babies
Babies are human just like the rest of us, but if you look at some of the ways they develop and behave, it may seem like they're a completely different species. In the second trimester, for instance, fetuses grow mustaches. This fine hair, known as lanugo, eventually spreads to cover the entire body. Shortly before birth, each hair is shed one by one and eaten, then excreted in the baby's first bowel movement. Taste is different than in an adult human, too. A newborn has tastebuds not only on the tongue, but also on the cheeks, tonsils, and the back of the throat. Babies have massive eyes, as well: while their heads are a small fraction of their adult size, their eyes are already 75% of the size they'll be in adulthood. To assist with birth, babies' bones aren't finished forming when they enter the world. Connections between joints fully develop later, so they have about 100 more bones at birth than they will in adulthood. We've collected some awesome videos on this topic.
