Pacifiers are not recommended for newborns at 10 days of age. Newborns aged 10 days should be breastfed as much as possible. At this point, as long as they are fed on demand and nursed once at night before going to bed, the baby will mostly not cry and will not need a soother. Generally speaking, the psychological needs of babies under 6 months of age are still relatively low, so try not to use a soother first. As the baby grows older, the psychological needs become higher, and discretionary use can be considered when it is necessary to use a soother. The long-term use of a soother creates a psychological dependency in infants, so if the soother is suddenly removed or if it is accidentally dropped, the child will cry. In addition, the use of soothers by infants who are too young may affect the development of their teeth and their oral health. Pacifiers that are contaminated with bacteria can also cause gastrointestinal symptoms in infants. If you do need to use a soother to put your baby to sleep after the age of 6 months, it is important to choose a soother of the right type and material, and to pay attention to hygiene and disinfect the soother in time after use to avoid oral infections in the baby.
