After the baby is born, new parents will sometimes find that when the baby sleeps, he can't help but grin, and even giggle and laugh out loud, it is simply a little angel, and the mother's heart will melt. Did she dream of something to eat, something fun, or something particularly happy about her dreams? This also made many mothers curious and funny, and they took out their mobile phones to take pictures and record this wonderful moment.
I often listen to the elderly at home say that the baby learns the skill when he sleeps, and if the baby learns, then he will laugh. Some say "the fight is won", "dreaming of delicious food", "the girl who sends the child is teasing the baby" and so on. However, these are the claims of the older generation, and there is no scientific basis for them. So why does the baby laugh when he sleeps?
There are probably the following situations in which the baby sleeps and laughs, but there is one situation in which parents should take the baby to the doctor in time
First, instinctive reactions
Studies have found that the baby's laughter and crying in dreams are an instinctive reaction.
As long as the baby eats enough and sleeps comfortably, the corners of the mouth will rise and show a smiling expression. If they feel hungry, cold, peeing, or uncomfortable, they will cry. These are instinctive reactions, don't worry.
Second, the baby's eye movement sleep, shallow sleep
The sleep cycle is divided into three types: eye movement sleep, shallow sleep, and deep sleep.
When the baby is in the eye movement sleep and shallow sleep stage after falling asleep, because the sleep is not very heavy, the brain waves are very irregular, so there are often eye movements, frowns, smiles and other behaviors. Even because of some small movements, they will wake themselves up. In fact, this shallow sleep is also good for the baby's brain development, which can stimulate the baby's brain development. Moms don't have to worry, it's a natural situation.
Third, the baby dreams
Some mothers will ask ," does a baby dream at such a young age?" ”
In fact, when the baby is still a fetus, he will dream when he stays in the mother's body until 8 months. Some expectant mothers will also see their babies smiling during the obstetric examination.
For example: the baby is too excited and happy to play with his parents during the day, and he sleeps at night and dreams that he is still playing with his parents, and he is in a very happy mood, and he may laugh.
In short, mothers don't need to worry, don't bother, just let the baby continue to sleep.
Fourth, brain development
The baby's brain development after birth is not perfect, because the brainstem and nerve limbic system are in a state of excitement, when the facial muscles are stimulated by the outside world, they will respond, if this movement is just the same as the smiley face, then the parents see the baby laughing; whether it is conscious laughter, or instinctive laughter, it shows that the baby's brain cells are developing rapidly, which is a sign of normal brain development.
Fifth, the baby's distress signal - traumatic brain injury
Moms pay attention to the fact that the baby is asking for help from the mother.
If the baby laughs loudly when sleeping, and is accompanied by limb twitches, unresponsiveness, vomiting, drowsiness, etc., it is likely to be caused by cranial nerves, and traumatic brain injury is common. If you fall out of bed and suffer a head impact, the baby may not be abnormal at the time, but after a while, there may be continuous laughter at night. Once such a situation is found, take the child to the hospital in time.
