Pacifiers are used to soothe babies when they are irritable, crying, uncomfortable and need to be temporarily quieted down. For example, vaccination, routine medical examination, the doctor needs to listen to the time, repeated, hard crying will affect the doctor’s diagnosis, then you can temporarily use the soother. In fact, it is not advisable to use the soother frequently, as it may affect the baby’s milk intake and may make the baby dependent on the soother. In this way, as the baby grows older, the use of a soother can affect the development of the teeth when they erupt, for example, the teeth can be misaligned or jaw deformities can occur after the teeth have erupted, so soothers should not be used if they are not needed in principle, and should be used sparingly if they can be used sparingly.
