When it comes to having children, many people will think of a trip to the ghost door, indeed not only to endure the pain of level 12, but also to appear various dangers at any time.
Even if you have never given birth to a child, you have seen similar scenes on TV, especially costume dramas: screaming mothers in pain, busy midwives, hot water and scissors (for cutting the umbilical cord) next to them, and you can really feel the pain and tension across the screen.

People who have not experienced it and do not understand it will also be curious: if you do not give birth to a child without anesthesia, will the baby hurt when cutting the umbilical cord?
Next, we will explore the knowledge of "newborn babies and umbilical cords".
Pregnancy: How does a tiny umbilical cord connect mom and baby?
Many people will be curious about the baby's umbilical cord, how does a small umbilical cord connect the mother and the baby?
When did this little umbilical cord form?
What does the umbilical cord do?
Does cutting the umbilical cord affect your baby?
What a magical and interesting question, let's take a look at it with Jing Mama!
Let's first look at what is the umbilical cord?
The umbilical cord is the life of the fetus and the pregnant mother, which is what we commonly call the lifeline.
One end is connected to the fetal placenta, adsorbed on the mother's uterine wall, the other end is connected to the fetus's navel, a steady stream of nutrients through the umbilical cord to the baby's body, while the carbon dioxide and other wastes generated in the fetus are also discharged from the baby's body through the umbilical cord, and the mother handles it on behalf of the mother. So the umbilical cord is a magical presence.
Physiologically, the umbilical cord is actually three blood vessels, one large vein flowing from the placenta to the fetus, and two arterioles flowing from the fetus to the placenta.
When did the umbilical cord start forming?
I thought about it when I was pregnant and looked up a lot of information.
The umbilical cord is formed in the first trimester, and more precisely, at four or five weeks of pregnancy, it begins to form from the villous tissue around the navel of the fetus, which is also the earliest placenta and umbilical cord.
At 40 weeks of pregnancy, the umbilical cord is of great significance to the fetus, not only as a "transportation pipeline", but also as an ideal toy for the fetus.
With the gradual development of the fetus, from the embryo gradually grows into a small fetus, the internal organs, nervous system, motor system continue to develop, the fetal baby differentiates the fingers and toes and can move flexibly, and the limbs can also roll in circles in the womb at will...
In this tiny womb, the umbilical cord became their only toy.
Childbirth: Cut and maintain, complete the mission, and retire
By about 40 weeks of pregnancy, with the birth of the baby, becoming an independent individual, the mission of the umbilical cord is about to be completed, and it is finally possible to retire.
When is the umbilical cord usually cut?
After the baby is born.
Exactly, how long after the baby is born?
In the "Regulation of Midwifery Techniques", it is stipulated that the umbilical cord of the newborn is cut about 20 seconds after completely detaching from the mother, and the connection between the newborn and the mother is disconnected.
The World Health Organization's recommendation is that the best time to cut the umbilical cord is the "golden minute" after birth, or after the newborn's umbilical cord has not fluctuated.
However, in the actual operation of the delivery room, some doctors said that it was too early to cut the umbilical cord within one minute. To be a little later, consider:
Let the baby get enough oxygen to avoid brain damage caused by lack of oxygen; let the blood in the umbilical cord continue to flow into the newborn; the concentration of stem cells in the umbilical cord is high, and late umbilical cord cutting can allow stem cells to enter the baby more.
When I gave birth to my husband was in the delivery, the doctor asked him if he wanted to cut the umbilical cord, he said he did not dare, afraid that I and the child would hurt...
But when the umbilical cord is cut, I can't feel whether the child hurts or not, but I don't feel it at all.
The doctor put it this way: Mom didn't feel it when she cut the umbilical cord.
Because human nerves are divided into non-autonomic nerves and autonomic nerves. It is the autonomic nerves that can feel the temperature change and pain; the non-autonomic nerves are not controlled by the brain and are mainly distributed in the blood vessels and internal organs, while the non-autonomic nerves that control the constriction of the blood vessels in the umbilical cord are non-autonomic nerves, and when the umbilical cord is cut, naturally they do not feel pain.
Then when the umbilical cord is cut, the placenta has been mostly stripped from the mother's uterine wall, and the pregnant mother will not feel when the umbilical cord is cut.
Does the newborn baby hurt?
In fact, it is basically not.
The newborn baby's nervous system is not yet fully developed, the pain perception and perception ability are relatively weak, and the pain when cutting the umbilical cord is not obvious to the newborn baby.
But when the baby cuts the umbilical cord, it is not because of pain and why?
This is before the umbilical cord is cut, the newborn baby's lungs have not yet begun to "put into use", but to become an independent living individual, the baby needs to breathe on its own, at the moment of cutting the umbilical cord, spontaneous breathing is established, and the baby experiences the first breath in life.
The lungs need to dilate and gulp down the air from the outside, and the air hits the vocal cords, making the baby cry.
Postpartum: What if your baby doesn't cry, or cries weakly?
Normally, as spontaneous breathing is established, your baby will have the first cry.
But there are also some special cases, the baby can not make a cry after birth, it will be more dangerous, the doctor will usually stimulate the baby to cry by playing the sole of the foot, because the baby's foot has a lot of nerve reflex areas, when the reflex to the pain nerve, the baby will cry because of pain stimulation.
Some doctors will gently pat the baby's back and buttocks to make the baby cry, thereby promoting the expansion of breathing in the lungs; or turn the baby upside down to make the baby's lungs expand rapidly.
However, if through these operations, the baby is still crying weakly or there is no crying, it is necessary to consider whether the baby has choked on amniotic fluid in the body, there is respiratory distress, and if necessary, the doctor will give the baby oxygen for 20 minutes, while observing the baby's face, muscle tone and other conditions for comprehensive judgment.
Little Umbilical Cord University asked, after reading the knowledge, right? Don't you think that both the umbilical cord and the new life are magical?
After the baby is born, a series of new troubles will follow for the new mother: how to feed the baby, how to change the baby's diapers, how to judge whether he is full or hungry, whether some conditions are normal...
Inexperienced new moms can be tossed to the point of collapse by these problems. But don't be too anxious, the upbringing of babies before the age of one is regular, as long as you master these "parenting codes".
