Should a nine year old suck their thumb?

At nine years old, thumb-sucking is generally considered a behavior that should be addressed, as it can lead to dental issues and social stigma. While it's common for younger children to suck their thumbs for comfort, older children may benefit from finding alternative coping mechanisms. Encouraging them to engage in other calming activities or discussing their feelings can help them move away from thumb-sucking. If the behavior persists, consulting a pediatrician or dentist for guidance might be beneficial.
