Newborns sometimes smile inexplicably, what s going on?

It's because I feel very comfortable, so I express my satisfaction through a smile, and my mood is very high.

This is normal. This is because after the baby is born, the cortex of the brain is very active, which causes laughter, which is normal.

Because newborns may suddenly want something more fun, they will laugh inexplicably. And some babies have a lower laughing point and will laugh in their sleep.

Most of the babies are in a state of light sleep, and if the baby snickers, he may not have entered a deep sleep, some babies may also have frowning, humming, twisting the body, which is some of the manifestations when he enters deep sleep in light sleep. The old people say that after the baby falls asleep, the dream will teach the baby to learn in the dream, if the baby learns better, the dream will be happy to praise him, the baby will laugh happily, if the learning is not good, the dream will criticize him, and then the baby will cry!

It is normal for newborns to snicker, frown, and move their limbs when sleeping, which is related to the child's sleep pattern. Newborns sleep about four-fifths of the time every day, and good sleep is important for the growth and development of children. For such a young baby, the cerebral cortex is already developing, so the baby will also think about it day and night, and when he dreams of something that will make him happy, he can't help but smile.

When most babies are born, their nervous system is not fully developed, and they sleep in a light sleep state many times, which accounts for half of the time. In light sleep, various expressions will appear on the face, this is because the baby is well fed by you, and his physiological needs are met by eating, drinking, and sleeping.

During infancy, their sleep state alternates between deep sleep and light sleep. During light sleep, there will be some physical movements, such as smiling, frowning, squeezing eyes, and even waving arms and kicking legs. At this time, parents must not think that the baby is about to wake up, in fact, it is still in a state of sleep.

When the baby is in light sleep, the brain is actually still carrying out thinking activities, and various expressions will appear on the face, and even make sounds, but don't worry, this kind of light sleep does not affect the baby's development, but will help the baby grow.

It's because the baby is dreaming, so he laughs in his sleep. There is also a situation that the baby's cranial nerves are not yet mature and cannot control their facial expressions.

This is because the newborn may be dreaming and, in general, may already be in a deep sleep. So it will suddenly laugh when you sleep.

It may be because the baby is dreaming while sleeping, so he suddenly laughs, or it may be because the baby is sick, and this laughter is usually caused by epilepsy, so the child should be taken to the hospital immediately**.

It may be that the child is dreaming, or it may be that the child is in a very happy mood, so he suddenly laughs when he sleeps. It's just an expression.

At birth, the child does not have control over his facial expressions, and he does not know what laughter is, so the laughter of newborns is an unconscious reaction. The newborn smiles a little while sleeping, which is just a natural reaction of the body's muscles and is not controlled by the brain. Because a child does not know the meaning of laughter, it is impossible for him to smile on his own.

According to the law of human growth and development, at the age of 0 3 months, the child can only make some unconscious sounds, cannot speak, and does not understand what a smile is.

I also did some research on the Internet and found that newborns will smile when they sleep, which is also very normal. Because the newborn's facial expressions and facial muscles are not controlled by the brain, it is normal for him to smile a little while sleeping. Children don't know what a smile is, but for adults, a child's smile is cute, and it makes adults feel very happy.

So although we don't know why children laugh, when we see children smiling, our mood will improve, and we can make mothers very happy. At 0-3 months, the child cannot make some conscious sounds at all, and can only make unconscious crying or unconscious smiles.

Although newborns don't know what a smile is, adults don't like children to cry very much, and adults are happier when children smile. And after giving birth, the mother's body will secrete a special hormone, which can make the mother very loving to the child and make the mother feel very sorry for the child. Therefore, under the effect of hormones, mothers will think that the child's smile is very beautiful, and they can make their mood better, which is also very magical.

It may be because the baby thinks of some happy things when he sleeps, or it may be caused by the baby's nervous system reflexes, so this behavior occurs.

It is because the child will feel very happy when he sleeps, or it may be because the child has some sweet dreams while sleeping, and he will suddenly laugh.

It may be that the child is dreaming, or it may be that the child feels very comfortable in life, so he will suddenly laugh, such an expression must be very **.

When the mother is taking care of the newborn, she finds that the child will always suddenly laugh when he sleeps, not because the child will show a happy expression. It's just that the child's expression will laugh unnaturally in his sleep, and the child will not realize that he will laugh at all, because the child's expression will be like this when he is born. Parents will feel very warm when they see their children laughing, because when the baby laughs, the corners of his mouth are slightly raised, and he will feel that the child is very cute.

Most mothers will find that the child will laugh uncontrollably when observing the child's sleep after giving birth, and the parents will see that after the child laughs, they will feel very happy in their hearts. They think that the child shows a happy expression, but in fact, after the child is born, he does not understand what it means to be happy. The child will have a smiling expression, mainly because the child's expression development will make the corners of the child's mouth go up directly, and the child will not be able to realize that he is a smiling expression.

Newborns eat, sleep, sleep and eat all day long, and parents need to understand their children in advance when taking care of newborns, and it is impossible to understand how happy expressions should be expressed? Because the newborn's vision is 1 to 2 months old, the child is relatively blurry, and he can't see the outside world clearly. Parents will feel very heartwarming when they see their child's smile, because of the child's involuntary expression.

Parents should be aware that younger babies in the formative months are the ones with very little smiles. When the child is more than three months old, and then slowly cultivates the child, as long as the parents smile at the child, the child will also face the parents with a smile. This is because the child is slowly able to control his facial expressions, and when the child shows that he is very happy, the child will respond to the parent with a smile.

The baby is happy, and usually laughs when he sleeps, which is a very normal situation, and there is no way to control his expression.

It may be a dream, it may be a physiological reaction, it may be a pathological cause, this is a normal phenomenon.

I think it's happy, because the baby's world is very simple, and it's also very kind, so I think it's happy.

It should be very happy, or it is in a good mood, or it is possible that you dream about something that makes you happy, so you will laugh when you sleep.

It takes about three or four days to laugh because children have had this sensory ability since ancient times, and they usually laugh when they encounter something happy.

Babies generally laugh at the age of four months, because at this time the baby's imitation ability is relatively strong, and he will laugh when he sees his parents laughing.

The child begins to smile at about 5 months of age, because the child's expression is gradually enriched at this time.
