Baby crying? Is the baby hungry? Is the baby sleeping too little? The app lets the baby fall asleep as soon as possible by playing carefully processed sounds. All sounds are free and more sounds will be added later.

Software can't replace the parents' love, patience and daily companionship. Cherish the baby's distressed time, they will grow up soon~
The sound that makes your baby quiet is the first sound that the baby will experience. Generally speaking, the baby's ear begins to form around 8 weeks of gestation. After about 20 weeks, the baby can not only hear the mother's blood flow and heartbeat, but also hear the outside voice through the abdominal wall. The study found that the first sounds the baby experienced during the fetus were "the sound of amniotic fluid shaking, the heartbeat rhythm of the mother, and the sound of blood flow in the blood vessels." So when they are born, they will feel relaxed once they hear a similar sound.
Mother's heartbeat
Mother's heart beats about 60 times per minute in a quiet state. This rhythm can calm the baby and make him feel more at ease. Therefore, it is recommended that your mother keep the baby close to her heart when breastfeeding or sleeping, so that your heartbeat can give your baby some comfort.
Mother's blood flow
The sound of blood flow in our impression is "squeaky", but this is actually the sound we hear through the muscles, and we can't hear some of the higher frequency sounds. The blood flow heard by the fetus in the mother's stomach is the part of the high-frequency sound, so it sounds a bit like white noise. The so-called white noise refers to noise in which the power spectral density is uniformly distributed throughout the frequency domain.
Sound of amniotic fluid
The fetus has always been surrounded by amniotic fluid in the mother's stomach. The sound of the amniotic fluid he heard should be like the sound we heard when swimming into the water. Even if adults hear the sound of the river flowing, they will feel peace of mind. This is probably related to the sound of amniotic fluid in the mother's belly.
Can simulate these sounds to comfort the baby
Since "mother's heartbeat, blood flow and amniotic sound" can play a role in comforting the baby, then when the baby is crying, the mother may wish to simulate these sounds to help the baby to calm down.
Pat the baby's buttocks and the back to simulate the mother's heartbeat at a frequency of 60 beats per minute.
When the mother is sleeping, the mother usually pats the baby's back or ass. The study found that if the mother can beat at a rhythm of 60 to 70 beats per minute, the baby will fall asleep more easily.
White noise = mother blood flow.
White noise in daily life refers to the sound of machines such as washing machines and vacuum cleaners.
The sound of running water = mother sheep sound.
Turning on the sound of running water from the faucet is very helpful in promoting your baby to fall asleep as soon as possible. But in order to avoid waste, mothers can also try to make a mouthful of water in their mouths, like a mouthwash. It is said that this is very similar to the sound of amniotic fluid heard when the fetus is in the mother's stomach.
