When a newborn baby cries and laughs in his dreams, is there no problem with his hearing?
The crying and laughing of newborn babies in dreams has nothing to do with hearing, it is an instinctive reaction.
How to determine whether a baby’s hearing is normal?
Newborn hearing screening is performed during hospitalization when the baby is 3-5 days old. For babies within 42 days of birth, the initial screening does not "pass", or the initial screening Children who are "suspicious" in the screening, or even "passed" in the initial screening, are considered to be at high risk of hearing loss and need a second or even third hearing screening to help determine the child's hearing condition. As babies continue to develop, their hearing will gradually develop and improve. In daily life, children of different ages also react differently to sounds. For example, a baby 1 month after birth will react to sudden stimulation. Two months after birth, when stimulated by loud sounds, babies may startle, open their eyes, and tremble in their hands and feet. Three months after birth, sounds can make the baby turn his head or move his eyes. 4 months after birth, the baby will turn his head to search when his name is called and is very sensitive to the mother's voice. Six months after birth, if you speak or sing to him, he will look at you with his eyes, track the source of the sound, and quickly find the place where the sound is coming from. Of course, these are not absolute, that is, we cannot rely on superficial manifestations to confirm whether a child has abnormal hearing. They can only be used as a preliminary judgment or as a preliminary basis for whether further examination is needed.
The baby cries and laughs while sleeping, which is an instinctive reaction
Let's take a look" The meaning of "smile" is a way of expressing joy, joy and happiness between people, and it is a means of communication between people.
It is obvious that newborn babies do not yet have the ability to communicate with others. The laughter they display is an instinctive reaction, such as eating When they are satisfied and comfortable, they will raise the corners of their mouths and smile; but if they are hungry, pee or feel uncomfortable somewhere, they will grin and cry.
So, for newFor newborns, crying or laughing during sleep are instinctive reactions. It is not until the babies slowly get to know their mothers, form a visual memory, and equate the mother with the "food source" that their laughter and crying have real meaning.
Whether the baby cries or laughs while sleeping is a problem with the sleep cycleWe know that sleep is divided into three categories according to depth: Light sleep, deep sleep and eye movement sleep. Among them, in light sleep, the baby can perceive the surrounding sounds, and the baby in this sleep state can sense what is happening around him; in deep sleep, the perception of the outside world is very weak, and breathing is slow and rhythmic; eye movement sleep refers to when sleeping The eyes will move left and right, and occasionally large-amplitude brain waves will appear, which are very irregular. The body will make some small movements, and the face will appear to smile, frown, or cry. The reason why the baby cries and laughs while sleeping is because he is dreaming
Some mothers may say: "A baby like this will Are you dreaming?”
In fact, both adults and babies can dream, and even babies have already started dreaming when they are still fetuses.
Studies have proven that the fetus’s nervous system begins to gradually develop and mature around 8 months old, and it has already begun to dream in the mother’s body. However, the fetus at this stage spends most of its time sleeping in the mother's body, so the pregnant woman may only feel the baby kicking her belly.
Generally speaking, babies' dreams occur in the light sleep stage, and the experiences during the day will be repeated in the baby's mind, that is to say, during sleep The dreams he has during the day are likely to be related to his life during the day. For example, if he has fun during the day and his parents are with him well, he may laugh in his dreams; if there is something that makes him unhappy during the day, or he sees something that scares him, He will probably cry in his dreams.
In short, it is a normal phenomenon for a baby to cry or laugh while sleeping, which is helpful to the baby's physiology and psychology.Yes, mothers don’t need to worry.
