Pacifiers can be used in infants and young children, but should not be used more often. Pacifiers have a certain soothing effect, have a certain calming effect, but do not have much special effect on the relief of colic. You can use a soother to calm your baby’s emotions, and if the baby stops crying and inhales less air into the intestines, you can reduce the colic caused by flatulence. At the same time, it is better for the baby to develop the habit of breathing through the nose. However, if you use the soother for too long, more than 10 hours a day, it is likely to form the upper jaw convex situation affecting the aesthetic. Usually use the pacifier for 15 to 20 minutes and stop using it as soon as the crying stops. It is even less recommended that the child fall asleep with the pacifier in his/her mouth.
