White noise can mimic how babies feel in their mother's womb, and it is considered a sound therapy that calms and relaxes --- "The Happiest Baby"
White noise is a sleeping artifact, can quickly and easily let the noisy baby fall asleep, the mother does not have to hold while walking while shaking and singing, but I still have a lot of novice parents around do not understand what white noise is, where can you find the right white noise, or the wrong use of white noise, did not achieve the effect of coaxing sleep, today's article once clarified.

The missing fourth stage is an important reason why babies need white noise
Dr. Harvey Kop, the inventor of the famous 5s appeasement method, called the first three months of the baby's birth the "missing fourth stage", and he believed that in many ways, the newborn baby is actually closer to the state of the fetus.
In the first three months of life, newborns are still too fragile, and if they can jump back to the original gestation environment, it is best for them.
What was the original nurturing environment like?
The fetus is curled up
Firmly wrapped in the warm walls of the uterus
Most of the day is spent rocking and swinging back and forth with Mom's movements
Surrounded by a constant "boo" sound (white noise).
Therefore, if you can provide a uterus-like sleeping environment for newborns, you can avoid many sleep problems and make a good start for your baby to learn to fall asleep on their own.
In fact, we can do it naturally with both wrapping (family in their arms) and shaking (shaking as we walk), and traditional experience has always been, although this is not the right way to do so.
But for the part of sound restoration, we always stay in the misunderstanding, not only no white noise, but also try to create the wrong environment - especially quiet, the family atmosphere does not dare to come out, creeping quiet.
What kind of white noise your baby needs
White noise ≠ noise, it refers to the power spectrum density of the wavelength component in a sound is uniform throughout the audible range, and the white noise that the baby needs is the same sound as the fetal period, so as to achieve the "reduction" effect.
So what is the white noise that the fetus hears?
In the early 1970s, doctors put miniature microphones in the wombs of pregnant women and found that the sound was 80 to 90 decibels! Even louder than the working sound of the vacuum cleaner - "The Happiest Baby"
If you still can't understand, try to hit the faucet to the maximum, fill the basin with water, and put your head into the basin to listen, and the whirring sound is similar to the sound environment of the fetus.
Commonly used, can be used as a sleep of white noise are: wind sound, the sound of the waves, bonfire sound, etc., campfire burning sound is what I have used before, more suitable for my children to sleep white noise, basically listen to a minute or two to fall asleep.
It sounds a little noisy to us adults, but the fetus is immersed in this constant, rhythmic white noise 24 hours a day and sleeps quite well.
After the baby was born, it was replaced by a quiet, empty sound environment, but there were sleep problems.
We can also see a strange phenomenon, those who sleep in a noisy environment from a young age, but it is easier to fall asleep faster and sleep calmly than babies who sleep in a quiet environment.
By what means can white noise be obtained
We can provide white noise to the baby in the following ways, each way has its own advantages, and everyone can choose the right one according to their own home situation:
1. Make a "booing sound" with your mouth
This method is also a link in the 5s appeasement method, when the baby is upset, we directly pick up or let the baby lie on the bed with the package on the side, pouting at a distance of 5-10 cm from the baby's ear, making a "boo" sound.
The advantage of this method is that it can respond to the baby immediately, quickly and conveniently, because the mother is very anxious when the baby cries, so the booing can quickly stop the crying.
The only drawback is that it is too much to test the mother's lung capacity, especially when the baby is crying seriously, the frequency and volume of the booing should be greater than or equal to the crying, so that the baby can get rid of the world of his own sound, I have tried this intensity of booing to soothe, after a dozen booing, I will breathe heavily, and the mouth is also dry.
However, if it is a mild cry, combined with the side-lying wrap light shake method, a small booing can quickly activate the baby's calming reflex, and then quiet down to sleep.
2. Use vacuum cleaner and hair dryer
The sound emitted by the vacuum cleaner and the hair dryer can also be used as white noise, but can not be placed in front of the baby, the record is kept at a distance of 2 meters, it can be slightly higher than the baby's crying, after the cry is reduced to calm, you can take it farther, reduce the volume or turn it off, switch to the sleep song, if you really can't move, the baby is noisy and noisy, you can use this trick.
But the disadvantage of this method is that it is not convenient enough, another person needs to help open the machine, and the tacit cooperation of the two people, if the mother is alone at home to coax the child, there is no opening and closing the machine.
3. Use the white noise played by the sleep app
The simplest way is naturally to use the recorded white noise audio, now many software have such a sleep white noise album, not only has a wealth of white noise, but also a variety of gentle sleep songs, open the phone when sleeping and then connect the speaker, the phone is held in the hand, the finger is placed on the side of the volume key, according to the baby's cry intensity to adjust the volume of white noise at any time, improvisation is very convenient.
Here is a small detail, it is best to use the mobile phone to connect a small speaker to play, the effect of the white noise released is better, because after the volume of the mobile phone is adjusted, it will be distorted, listening to it is very harsh, affecting the effect of white noise.
This method is more suitable for daily sleep, open the white noise in advance, but not suitable for crying serious sleep mode, this time, need to combine the first booing method, first with a short rhythm, strong booing to activate the sedative reflex, after stopping crying, open the phone to play white noise to sleep.
Why did I let out the white noise, but the baby still cried
White noise is indeed scientifically based, and mothers who have successfully used white noise will feel very magical, lamenting that it only takes a few seconds to make the crying baby quiet down instantly.
But there are still many mothers who have no effect after using white noise, because there are errors in the details of the operation.
1, did not find the white noise suitable for their baby
There are many types of white noise, wind sound, rain sound, wave sound, heartbeat sound, etc., each child's "taste" is not the same, so the mother needs to try many times, open the white noise when the baby is slightly sleepy, and then observe the baby's reaction, if he can immediately quiet down, like a sudden wandering mind, this white noise is appropriate, if the baby is more irritable, then immediately replace one.
2. The intensity of white noise does not match the baby's crying
When the baby is crying, it is surrounded by its own crying, and it is impossible to hear the words you say "don't cry, don't cry", nor can you hear the white noise that is too low in intensity, such as the sound of the waves, the sound of insects, the sound of the stream, it has no meaning at all.
At this time, open a hair dryer, vacuum cleaner (pay attention to the 2 meter position), or in the baby's ear (5-10 cm position) strong, fast booing, to be greater than or equal to the volume and intensity of the baby's crying repeated use, in order to open the calm reflection switch, if necessary, but also with the wrapping method, side lying method, shaking method, 5S soothing method A complete set of use.
Next, as the baby's cry is adjusted, the white noise intensity is adjusted, the crying is getting smaller and smaller, the white noise is getting smaller and smaller, and the baby can't all be quiet, and we are still there to boo and boo.
Here is a set of white noise combination punches recommended for sleeping, and I have tried it many times: artificial booing + mobile phone playing white noise / sleep song.
Here's how:
When the baby is upset, the booing quiets it down
No more crying, the boos are getting quieter, press the start button to open the white noise album interface in the app in advance, and cut the white noise in
The boos stopped, the baby's eyelids began to fight, and the white noise continued to play
Your baby's eyes slowly close and reduce the volume
Finally fall asleep and turn off the white noise
In the whole process, the mother should pay attention to observe the baby's response to the white noise, from his expression, demeanor can be captured, often observed, can help the baby and the white noise to establish a connection, practice can make skill, when trying the white noise to stop crying and sleep sweet, no longer want to shake with milk.
