Newborns can usually start using a soother after three weeks of life, depending on the child’s acceptance. Generally after three weeks of life, when a newborn baby cries more than once due to poor sleep, indigestion and other reasons, a soother can be used appropriately. Appropriate use of a pacifier can calm the newborn and help restore calm quickly, and can also exercise the sucking response of the newborn. It should be noted that if the soother is used for a long time, it will make the newborn dependent, and may affect the development of lips and teeth. When a newborn baby is always crying, it is important to seek medical attention to find out what is causing the crying and to deal with it effectively.
