Many novice mothers will imagine that the baby is an "angel" when they are born, white and clean, pink and tender. In fact, newborn babies are not very beautiful. Almost every baby will have white fetal fat at birth, but some babies are more and some babies are less. So, what is the function of fetal fat?
① The function of keeping the baby warm.
The uterus is full of normal body temperature. The baby won't be cold inside, but it will be different when it comes out. The temperature outside is colder than that inside the uterus. At this time, the baby's body temperature will be reduced to a certain extent. If you have fetal fat protection, you can have certain cold and warm-keeping ability to let your baby adapt to the temperature.
② Protect the baby's skin
Fetal fat can prevent dehydration of newborn baby's skin and protect baby's skin. Because newborn babies will have dry skin in the first few days after birth, especially hands and feet, which is a normal reaction of skin from a watery intrauterine environment to a drier external environment, and this situation usually lasts for several days.
Do you know the health standards for newborns?
Many novice parents are worried about whether their children are healthy or not. How to judge the health standard of newborn babies? The pediatrician said that if your baby meets these six standard indicators at birth, the mother can rest assured.
(1) baby's respiratory rate
After a newborn baby is born, he will cry several times and then start breathing with his lungs. His breathing was steady and regular, with 40-50 breaths per minute two weeks before birth. However, sometimes the newborn baby's breathing is fast and slow, and even has a slight pause. At this time, it is necessary to observe the specific performance of the baby and judge whether the baby has special circumstances, because the breathing of the newborn baby may be affected by many situations, such as crying, and the breathing will be accelerated during activities, which can reach about 80 times per minute.
(2) the baby's temperature
The newborn baby's body temperature is between 37℃ and 37.5℃ at birth, and it has been kept between 36℃ and 37.5℃ since then. Axillary is the most convenient and commonly used method to measure the temperature of newborn babies. The body temperature of newborn babies fluctuates greatly during the day, which is often lower in the morning, slightly higher during the day and higher at night. Therefore, the best time to take your baby's temperature is when you get up every morning and before going to bed at night. Don't take your temperature within half an hour after drinking water and eating, or after exercise, because your temperature will definitely be high at this time.
(3) the baby's height
It is normal for a newborn baby to be equal to or more than 45 cm tall. Regardless of the height of parents, the height of full-term newborns is about 45~50 cm, which is not closely related to heredity. As the baby grows older, the genetic effect begins to show that both parents or one parent is taller, and the baby's height is usually higher. If the congenital conditions are insufficient, parents should pay attention to feeding, encourage exercise, ensure sleep, create a harmonious family atmosphere, and create a happy and comfortable living environment for the baby.
(4) the baby's weight
The normal weight of newborn babies is generally 2500~4000 grams. Underweight newborns belong to immature babies, while overweight babies belong to macrosomia. The weight of a newborn baby generally refers to the naked weight, that is, the weight of clothes and diapers worn by the baby is subtracted.
(5) the baby's head circumference
The normal head circumference of newborn babies is between 30.4 and 37.9 cm. ? At the full moon, the average increase is 2~3 cm. The head of a normal full-term newborn is oval and relatively tall, and the head length accounts for about 1/4 of its body length.
(6) Baby's bust
The chest circumference of a newborn baby is smaller than its head circumference 1~2 cm, generally 3 1~33 cm. At the full moon, the chest circumference can reach about 36 cm. If the baby's chest circumference is too small than the head circumference, the baby may have hydrocephalus; If the baby's chest circumference is much larger than the head circumference, then the baby may suffer from microcephaly. Mom and dad should pay special attention.
