Patient's question:
Sucking fingernails before taking a nap since mid-2009 to date. Previous treatment history and effectiveness: None. What kind of assistance is desired: Wants to know the reason and how to treat...Doctor's answer:
For a child around 5 years old, mental tension is one factor that leads to nail-biting, and many other factors can also contribute to this behavior. For example, curiosity about nails, boredom with certain activities, feeling pressured, or simply developing an interest in nail-biting again after a few bites due to overgrown nails and discomfort can all contribute to this habit. Compared to other behaviors caused by mental tension, such as thumb-sucking or nose-picking, nail-biting is more common. In fact, almost all children have had the habit of nail-biting, and for many, it persists into adulthood. Approximately one-third of elementary school students and over half of teenagers still retain this habit, although many do it only occasionally. Nail-biting is unlikely to persist indefinitely. Once the child starts attending kindergarten or school, they may suddenly lose interest in nail-biting due to teasing from other children or being distracted by more engaging activities, leading them to break the habit.In terms of treatment, first, keep the child’s hands busy—give them toys to hold before bed. Also, remember to trim their nails promptly to prevent discomfort caused by overgrown nails from reinforcing the behavior. Second, don’t overreact to the child’s nail-biting. For a child around 5 years old, nail-biting is often an unconscious action, meaning they are not even aware of what they are doing until you draw attention to it. Using your methods, such as scolding them or gently removing their hands, can help them realize they are nail-biting. Because it’s unconscious, parental nagging and punishment will not significantly help change this habit. Instead, excessive attention to the behavior may make them bite their nails more frequently. Over time, nagging and punishment can make the child feel overwhelmed, leading them to reject the behavior as a way to cope with internal pressure.
Third, eliminate the factors causing the child’s stress. Moving, parental loss, difficulty adapting to kindergarten, feeling neglected by parents, being scolded by teachers, or being bullied by peers can all cause psychological stress. Parents can patiently talk to their child, encourage them to share their experiences, and provide emotional support. They can also ask how nail-biting makes the child feel. If parents validate their child’s feelings, it may bring them relief.
Fourth, work together with the child to eliminate the habit. Parents can explain the downsides of habits like nail-biting and discuss with the child how to change it, then work together to set a common goal. When the child bites their nails, they can agree on ways to remind them, such as gently tapping their body or making a specific sound, to help them remember.
