1. Psychologists believe that babies enter the oral period from birth to 2 years old. Sucking with the mouth helps the baby to transfer tension and enhance safety. In addition to nutrition sucking, babies can also promote the sense of touch near their lips and tongue by sucking, thus achieving satisfactory happiness.

2. The pacifier will encourage the baby to develop the habit of breathing through the nose. Breathing through the nose can prevent external viruses and pathogens from invading the body, but breathing through the mouth can't? At this time, children need something to "shut up", and pacifiers are a good choice. ? Some experts in Europe and America have found that a child will form the habit of silence when using pacifiers, which will naturally prompt them to learn to breathe through their noses.

3. Non-nutritive sucking is a way for infants to relieve their emotions. Without pacifiers, many babies suck their fingers to achieve their goals. Unclean fingers are easy to get sick, or suck your fingers to peel off. ? If you have this habit, it may affect the development of gums. ? In the latest research, a comparative survey of 500 American families with small babies found that pacifiers can reduce the probability of sudden infant death syndrome by 60%? This is because the pacifier will make the baby lie on his back or side, and will not increase the chance of sudden death caused by prone position. At the same time, eating pacifiers will help the baby get used to breathing through the nose, prevent bacteria and dust from entering the mouth, and effectively prevent "illness from entering the mouth"

Experts believe that the habit of sucking pacifier can be avoided within 2 years old, because it can be used to train infants' sucking and swallowing ability, especially for low-weight premature infants, which is helpful to improve their oral and gastrointestinal peristalsis and realize the function of self-appeasement.
