The early use of soothers is generally not recommended for newborns, but can be used in moderation and reasonably. 1. For newborns, especially breastfed children, the child’s breastfeeding habits have not yet been developed, so if you introduce a soother to your child during the neonatal period, it may disturb the child’s normal breastfeeding habits, which will have a certain impact on the child. 2. The introduction of soothers is generally recommended after the first month of life, or after the child’s overall feeding habits have been established, and can be normal milk intake, and then introduce the soother to the child, which is relatively safer, and will not affect the child’s breastfeeding habits. 3. Pacifiers can have a calming effect on the child, but they are not recommended for long-term use, especially not during sleep. Prolonged use of a soother may have an effect on the child’s dental growth and may also lead to an increased risk of choking.
