As a stay-at-home wife, I believe many parents have the same question as me, why do children pick up their arms when they sleep into a "surrender style".
Ever since my daughter Shin Shin was born, I have found that when she sleeps, her hands are always unconsciously raised above her head in a "surrender style", will your children be like this?

Now that Xinxin is four years old, I always find that when she sleeps, she always has to raise her hand above her head, and My father and I always put Xinxin's hands into the bed, because our northern winter has heating at home is not particularly cold, and the pajamas for children are also very thin, and his father and I are afraid of freezing her cold, because I often wake up to touch her exposed hands are cold. So, it was not too late, as long as Xinxin raised her hand above her head, I would force her to put it down.
However, over time, I found that even when we forced her hand into the quilt, she would flip around in the quilt, and her feet would move randomly, kicking the quilt all the time. Until the quilt is finished, the hands are released and automatically "surrendered" to sleep peacefully.
Once, when I went to kindergarten and talked to other parents, I inadvertently learned that other children had this "surrender" sleeping position. Speaking of other parents, they were also confused by this doubt, so I also became concerned about this matter. I happened to know a childcare doctor, and I relayed our confusion to the doctor, who looked at our problems very concerned and gave a very detailed explanation.
The doctor's explanation is summarized as the following points, which can be shared with you:
1. The reason why babies like to put their hands in a "surrender" style when they sleep
When children sleep, they like to raise their hands above their heads, mainly when the baby is in the mother's womb, because the position is curled up, and after birth, they are not very comfortable with this new environment and lack of security, so they use the surrender sleeping position to find a sense of security.
And parents do not have to worry, with the increase of age, the newborn's various organ functions are fully developed, this posture will gradually disappear. If you are afraid of getting cold in winter, don't worry too much. In addition, the correct sleeping position should be lying flat, with the upper limbs located on both sides of the body, and as the child slowly grows older, the child will also change to this position.
There are also many elderly people who say that when the newborn is "surrendered", they always say that the child is "holding the head of the tiger" and "earning long", that is, growing the body and supporting the tall. The paediatrician told me that this is also the embodiment of the healthy growth of children. Just like adults who are tired and stretch their waists, babies sometimes feel tired and will also make a move similar to "stretching their waists", that is, raising their hands above their heads to relieve fatigue.
In fact, there are many times, because the baby wears too much clothes, he will also raise his hand over the top of his head to achieve the purpose of heat dissipation and the quality of his sleep, so when the parents find that the child sleeps in a "surrender style", you can touch the back of the child's neck and back is sweating. If you sweat, you need to change your child's clothes in time so that your child can sleep more comfortably.
When the baby sleeps in a "surrender state", these small points must be paid attention to
1, when the baby sleeps in a "surrender state", do not stop it frequently. Many parents see their children like this, they will always take their children's hands off, in fact, it is not necessary. This will affect the quality of your baby's sleep.
2, always pay attention to the child's sleeping environment, if the child sleeps steadily, the sleeping environment is very important, and the indoor temperature can not be ignored, always pay attention to the child's body temperature, appropriately adjust the room temperature or give the child more or less clothes.
3, at the same time, the child's sleeping posture should also always pay attention to, bad sleeping posture will also be dangerous, first of all, it is lying on the stomach to sleep, lying on the stomach to breathe fresh air, it is easy to occur "sudden death" risk. The second is to sleep on the side, many children have the habit of sleeping on the side, if there will be pillows or plush toys on the side, parents should pay attention to avoid difficulty in breathing through the mouth and nose. Finally, the head is tilted to one side to sleep, which can easily lead to cramps in the neck muscles, not to mention, there will be a crooked neck phenomenon, which is easy to affect the temperament image.
