It is generally recommended to use a soother after the baby has reached the age of one month. Pacifiers have a very soothing effect on babies of small months of age, relieving physical discomfort, reducing anxiety, and satisfying the need to suck, among other things. The newborn period is a critical period for establishing the mother-infant connection and promoting the success of breastfeeding, so it is not recommended to use soothers for babies within the first month of life. Also do not use it all the time, it is recommended that you start to wean your baby off the soother at around 6 months of age. This is because as babies grow and their chewing ability increases, some babies will bite through the pacifier leading to the risk of swallowing and accidental sucking, while prolonged use of the soother will affect the cleft teeth and maxillofacial growth. Pacifiers are not a necessity, if you need to use it is recommended to establish a normal breastfeeding pattern, and at the same time in 6 months and above gradually quit the pacifier, you can choose other ways to soothe the baby, do not rely on a long time pacifier.
