9 Amazing Facts About The Umbilical Cord — AKA Your Baby's Life Support

Most moms are terrified at the thought of their baby's umbilical cord getting knotted or looped around baby's neck. Although there is a small risk of it becoming dangerous, Belly Belly noted that loops and knots are actually very common and rarely dangerous. The danger lies in a knot forming during labor, but since your baby moves so much in utereo, the occasional loop or knot is inevitable

The umbilical cord doesn't start off as long as it is when your baby is born. According to the March of Dimes, it begins forming at about four weeks and can grow to be as long as 22 inches.

Since the umbilical cord is a baby's main source of nutrients from the mother, it follows that an unhealthy mother would contribute to an unhealthy umbilical cord. One study from Reuters noted that in mothers who smoked during pregnancy, methylation patterns were foundd in blood cells in the umbilical cord, as well as in the baby's system.

Lately, many parents are opting to not clamp the cord at all, or at least delay clamping significantly. It turns out that clamping the cord isn't completely necessary. According to ABC News, it shuts off on its own about an hour after birth. The cord will dry up and fall off on it's own, just like the stump does traditionally, after about a week or so.

Cord blood banking is a common practice that can help to save another baby or child's life. According to Baby Center, you can choose to donate your baby's umbilical cord blood or save it in a personal bank for your families future use.

According to NPR, even delayed cord clamping has been shown to give baby a neurological boost in development that can benefit them for years down the road. Delaying the clamping also allows more blood to flow from the placenta to the baby, which can significantly increase baby's blood volume and iron levels, which are essential for healthy brain development.

Have you ever wondered why some babies have "innies" and others have "outies?" It turns out that the shape of their belly button is determined long before birth. According to Everyday Health, belly button shape is "caused" by a wide variety of things like belly shape, amount of scar tissue where the cord connects to the belly, looseness of the skin and more.

Although the cord won't look like a true "cord" for several weeks, the placenta and umbilical cord begin forming soon after baby is conceived, Today's Parent noted. The fertilized egg turns into two components: one is the embryo that will develop into your baby, and the other is the placenta. The umbilical cord develops out of the embryonic tissue and continues to grow until your baby is born.

Researchers are studying umbilical cord blood (UCB) stem cells for their "potential use for therapeutic application for nonhematopoietic tissue and cell regeneration," according to one study from the National Institutes of Health. Unlike research on other embryonic stem cells, UCB stem cells have less of an ethical debate and have equal potential, research suggests.
