When a baby is born, the brain does not have the skills to completely control the body, that is, the newborn can't control his facial muscles well. Therefore, the baby's laughter in sleep may be just an unconscious behavior, that is, the action without passing through the brain. This situation is actually very common in newborns. This phenomenon is not only manifested in sleep, but also in other very strange movements, even sudden crying. When this happens to babies, it actually shows that the brain is growing. Slowly, parents will see this phenomenon less and less until the brain is fully capable of controlling the disappearance of the body. Therefore, parents don't have to worry too much when the baby laughs or cries during sleep. The baby doesn't dream or dream, but simply acts unconsciously.
Babies not only dream when they are born, but also start dreaming when they are in their mothers' bellies. Because it grows in the mother's stomach, when the baby's nervous system is gradually improved, the baby can dream. Babies' dreams also reflect that their brains are developing normally or well. Because only when the brain is well developed can babies dream when they sleep. Therefore, when parents find that their children are always laughing or doing other actions while sleeping, don't worry that the baby will not get enough sleep because of dreaming, because the baby is actually promoting the development and growth of the brain. Newborns' emotions are more influenced by changes in external environment than by stable subjective mentality. The biggest emotional characteristics of newborns are impulsiveness, changeability and exposure. The younger they are, the more prominent their characteristics are. Therefore, when a newborn dreams, his mood will also be affected by the external environment, crying and laughing.
Newborns usually have a hearing test on the second and third day of birth. If there is a problem, the doctor will tell their parents. Bao Yue thinks there should be no problem with the baby's hearing. If you are really worried and not sure whether there is something wrong with the newborn's hearing, I suggest you go to the hospital for a hearing test. The baby is in a light sleep state, and the brain is actually still thinking. There may be micro-expressions or body movements of one kind or another, including smiling and sometimes giggling. The baby is dreaming. Maybe the baby dreamed that his parents were teasing him. He ate and drank, and was satisfied in his dream. He couldn't help laughing and even made a noise. His voice floated to the ground. It's so cute. Ma Bao couldn't help laughing. She feels that the trouble of taking care of the children has disappeared and all the efforts are worth it.
