Trimming the tongue tie is usually recommended at around 3 years of age, but can also be done after birth if there is a serious need. A short or long tongue tie can have an impact on the child: a child with a short tongue tie may have difficulty extending the tongue, breastfeeding, or pronouncing words, and the child’s tongue may be extended in a “W” shape, while a child with a long tongue tie may have difficulty pronouncing words and speech disorders. It is recommended to trim the tongue tie when the child is around 3 years old because trimming the tongue tie when the child is too young may cause scarring. Therefore, trimming the tongue tie when the child is 3 years old is not only more effective, but also the child has the ability to cooperate with the surgery, which makes the surgery process smoother. If the tongue tie is found to be too short after the child is born and it affects breastfeeding, you can also choose to trim it immediately, as the pain sensory nerves are still underdeveloped, it can reduce the pain of the child.
