Is ok to suck your thumb 11 years old?

While thumb-sucking is a common habit in younger children, it's generally considered less appropriate for older kids and preteens, like 11-year-olds. Prolonged thumb-sucking can lead to dental issues or social concerns, as it may be seen as a sign of immaturity. If thumb-sucking persists, it might be helpful to discuss strategies to reduce the habit with a parent or a healthcare professional.
