Why is the baby laughing while sleeping?

The first month after a baby is born is the most difficult month for new parents. Newborn Baby Care Encyclopedia Download Ultra Clear epub The fetus leaves the familiar womb and the newborn falls to the ground. Facing a completely unfamiliar world, he lacks a sense of security. Only in the familiar arms of his mother can he stop crying. Not only that, newborns have small appetites and need to be fed every 2 hours, even at night, making new parents feel physically and mentally exhausted. The only way for newborns to express their needs is through crying in various ways. New parents are inexperienced and rush to take care of their babies. Even though they are tired, they can\’t help but sigh, babies love to cry too much! Only in the dead of night or after the baby is asleep, does the mother have a moment of rest. After watching the baby sleep soundly, the mother finally breathes a sigh of relief. However, no matter how hard the day is, a mother will feel happy and satisfied when she sees her baby smiling innocently while sleeping. The baby\’s smile is so healing! However, what is strange is that most newborn smiles appear secretly after sleeping. Many mothers find that their babies do not smile automatically when they wake up. In fact, the fact that the baby smiles while sleeping rather than smiling while awake is related to the growth and development of the baby\’s brain. By this month, the baby will smile socially. Why do newborns laugh secretly after sleeping? When does a baby laugh? It’s related to growth and development. Why do newborns smile when they sleep? 1. The central nervous system is immature. Even if the baby is born at full term, although the weight and height are up to standard, because the baby is too young, the central nervous system is not fully developed and cannot control the facial muscles well. When a newborn\’s facial muscles twitch involuntarily, the corners of the mouth will rise slightly. This is an unconscious muscle reaction and is an involuntary smile. This unconscious muscle twitching in young babies looks like the baby is smiling. This phenomenon will disappear as the baby grows older. 2. Lightly sleeping babies will have 6 different states of consciousness, 2 of which are sleeping states and the rest are awake states. Human sleep is cyclical, and babies\’ sleep patterns are divided into two types: deep sleep and light sleep. In light sleep, the baby\’s sleep is not solid. There will be facial twitches, body jumps, trembling hands and feet and other sudden movements. This is the characteristic of light sleep. When the baby is in the light sleep stage, he will make some unconscious movements, such as smiling, frowning and other movements on the baby\’s face. Because the baby\’s brain is not yet fully developed and cannot freely control facial muscle expressions, so when the mother sees the baby laughing in his sleep, it is just an unconscious grin, not a spontaneous smile, and it does not make a sound. In deep sleep, the baby\’s movements will become less and less, the breathing will be more stable and relaxed, the baby will be very quiet, and the baby will sleep more deeply. A baby\’s sleep alternates between light sleep and deep sleep. Although light sleep is short, it is helpful for the brain development of newborns. If the mother finds that the baby always likes to laugh while sleeping, do not wake the baby up, and do notIntervene too much and just let the baby continue to sleep. 3. If your baby has cerebral palsy and has abnormal brain development, he may also experience facial twitching while sleeping. However, most babies smile while sleeping because their brains are not fully developed. How many months does it take for a baby to smile for the first time? Newborns smile mostly while sleeping, which is an unconscious smile. In fact, the baby\’s first spontaneous smile is not when sleeping or before the full moon, but when the baby is 1-2 months old, the baby will show its first real smile. When the baby is not sleeping but waking up, he looks into his mother\’s eyes and smiles sweetly at his mother. The baby\’s smile is as bright as the sun, making the mother feel happy and happy. 2-month-old babies often smile reflexively. They feel happy because of other people\’s smiles. They like to respond with smiles. A baby\’s heartfelt smile can help him get more attention from his mother. From birth to less than one month old, the baby only smiles unconsciously in his sleep. After 2 months, the baby can smile independently. By 3-4 months, the baby has entered the social period and will show social smiles. However, if the baby still does not smile when he hears his mother\’s voice when he is 2 months old, and does not smile at others when he is 3 months old, it means that the baby has not met the development requirements for this month of age. These may be abnormal development of the baby. It is a signal that the mother needs to take her baby to the doctor in time to see if there is any problem with the baby\’s brain development. Within 1-3 months after the baby is born, the baby completes the transformation from non-spontaneous smiles and autonomous smiles to social smiles. The baby will be more enthusiastic about social interaction, have stronger communication skills, richer facial expressions and body language, and also likes Mimic movements and facial expressions of adults. Babies like to use smiles to express their needs and interact with the outside world. The more frequent these interactions, the higher the degree of brain development of the baby. How do mothers usually interact with their babies to promote their brain development? 1. Language interaction Although babies at a young age cannot speak yet, if the mother can talk to the baby frequently, it can promote the development of the baby\’s brain, and the baby will respond by smiling, winking, etc. 2. Game interaction: The older the baby is, the wider his field of vision is and the objects he can see are clearer. Mothers can play hide-and-seek or eye-catching games with the baby. The more novel and interesting the game, the more stimulating the baby will be. The interest makes the baby laugh, which is also helpful for the development of the baby\’s brain. 3. Emotional communication For the baby, the mother is the most important person. His eyes will always follow the mother. As long as the mother is by his side, he will feel safe and can reduce the baby\’s crying and irritability. . Especially when the mother stares at the baby with a smile and talks to the baby softly, the baby feels the mother\’s care and love, and will also show an innocent smile. This kind of emotional communication can increase the baby\’s sense of security.
