"Sound of the womb" has a very simple goal: to be a useful tool to help calm the baby (especially newborn) and make him stop crying and sleep soundly almost as if by magic.
The idea is to use the sound of the mother's womb to make the baby feel more comfortable and relax. Just push the button on the smartphone or tablet screen to the sound start playing. Soon the baby will be calm, relaxed and sleep like an angel. While for adults the sounds seem annoying noises for babies they sound like a music able to transport them back to the safe environment of the uterus.
In addition to the sound of the mother's womb, the application has three other sounds that can be pleasing to the baby: shower sound, hair dryer sound and white noise. One of these sounds will be able to make your baby calm down.
And it works, right?
Yes. It's magic, believe me. The application has already been used by thousands of dads and moms who approved its effectiveness.
But remember that the method has no scientific proof. However, experts say that the sound of the uterus can indeed be used to calm the baby on occasions. One is American Harvey Karp pediatrician as shown in the video "The end of the baby's crying": https://www.youtube.com/watch?v=OPWFXJAZofM.
On the other hand, it should be used only when the baby is doing morning, not when you are hungry or cramps, for example.
