"On the 3rd day of birth, the baby showed a sweet smile when he went to bed after feeding, and at that moment, my heart, which had just been promoted to mother, was about to be cute."
Seeing my friend Lili's happy sharing, I couldn't help but think of my corn and pudding when they were born, and they often slept with angelic smiles, sometimes grinning, accompanied by happy laughter.
Whenever this time, my mother and my aunt will always say that the child is in class in his sleep, and Granny Dream is teaching the baby to learn skills, if the baby learns better and gets praise, if he does not learn well, he is criticized by Granny Dream, and the baby will cry.
Although there is no scientific basis for this claim, it sounds interesting.
Why do newborns smile when they sleep?
1. The baby is in a state of light sleep
Newborns are still very young, their brains and central nervous systems are not well developed, and they are not yet able to control their facial muscles well. When the baby sleeps, the facial muscles unconsciously shake, and the so-called smile appears.
In addition, the newborn is sleeping most of the time, and the sleep state is often alternating between deep and light sleep, when the baby is in a light sleep state, there will be expressions such as frowning, sobbing, smiling, etc., and many times it is accompanied by sucking, chewing, startle reflex and other actions.
2. The baby is dreaming
Many babies smile sweetly and even laugh out loud when they sleep, which makes the parents on the side can't help but sigh that the baby is too cute at the same time, but also wonder if the baby is dreaming.
Some people may ask: can such a young baby dream?
In fact, this is not the first time that the baby has dreamed, as early as when the baby is still in the mother's womb, he already has the ability to dream.
When the fetus is 7 months old, the cranial nerves are stimulated, and dreams occur. In general, fetal dreams can be monitored by brain waves, and can also be observed by ultrasound. When the fetus dreams, the eyes move at high speed.
This can be intuitively felt when the pregnant mother undergoes a four-dimensional color ultrasound during the pregnancy test.
3. The baby feels comfortable
When your baby is full, has eaten and drunk enough, or is in a comfortable environment, listening to soft and pleasant music, etc., your baby will smile spontaneously. The baby's smile before the first six weeks of birth is due to the baby's great physical and mental satisfaction, which is related to the spontaneous subcutaneous electrical discharge of the baby's cerebral cortex, but it does not have real social significance.
It should be noted that sometimes the baby will wake up laughing during sleep, at this time the mother or caregiver should try not to disturb the baby, let him quietly pass the light sleep stage by himself, and continue to enter the deep sleep stage.
When does the baby smile in the real sense?
The baby will smile just a day or two after birth, and many times he will smile in his sleep, but the duration is very short, and at this time the parents will feel very cute, and the baby will smile at this time. In fact, this smile of the baby is unconscious, and psychologists call it a smile of the mouth.
By the time the baby is two months old, he will start smiling consciously.
Psychologist Jean Piaget did a study and he observed that babies at this stage will not only smile at people's faces, but also sometimes smile at familiar toys and other toys on their hands.
From these phenomena, he came to a conclusion:
A baby's first smile is a manifestation of his or her cognitive or intellectual development, a recognition of a familiar object, not a sign of love, friendship, happiness or sociality!
By the time your baby is 3 months old, they have become "smile masters" and they are able to recognize their mom or other caregivers. When they see the face of their mother or caregiver, they will give a real smile. Sometimes, they will use bright smiles and giggles to attract the attention of their mothers or caregivers, and take the initiative to start "chatting" with their mothers or caregivers.
As babies smile more and more consciously, they learn to interact with others and enjoy the fun in the process.
At the same time, the baby's charming smile will make the parent or caregiver feel happy and deepen the bond with the baby.
Frequent baby laughter has many benefits, not only to promote the balanced development of the baby's whole body, various organs, so that the baby's body is stronger, but also for the baby's brain development is also a benign stimulus, conducive to the baby's intellectual development. In addition, from the perspective of mental health, babies who love to laugh grow up with a cheerful personality and an optimistic and stable mood.
Therefore, parents should interact with the baby more, and can use happy expressions, words or novel toys or pictures to make the baby laugh.
