Habits in Children – Are They Cause for Concern?

May 05, 2025

Habits are behaviors that are acquired through repetition, often becoming automatic over time. While some habits are beneficial, others can be concerning, especially when they seem to be linked to anxiety or cause harm. Habits like nail-biting, hair-twirling and humming are common in children, and while these behaviors may seem harmless, they can raise questions.

Common Habits in Children

Some of the more common habits that children may develop include:

  • Nail-biting
  • Humming
  • Clicking a pen
  • Whistling around the house
  • Twirling their hair

While these habits may seem negative, annoying or concerning, they are typically not harmful. In some cases, these behaviors can be temporary and resolve on their own.

When to Be Concerned About Habits

Certain habits may become worrisome, especially when they seem to indicate anxiety or cause potential harm. To determine whether a habit is cause for concern, you can:

  • Observe the behavior: Quietly watch your child without drawing attention to the habit. Take note of how often the behavior occurs, in what situations it happens, and when it is absent.
  • Assess its impact: Consider whether the habit is interfering with your child's daily life or well-being. Is the behavior happening so frequently that it’s becoming disruptive, or is it causing physical harm (such as damaged nails from biting)?
  • Determine discretion: Is your child bothered or stressed by the behavior, but struggling to stop or prevent it from happening?
  • Look for patterns: Some habits may come and go without any clear reason, and they often resolve on their own. Others may be more persistent and require attention.

If a habit appears to be causing harm or significant distress, it’s a good idea to consult with your child’s pediatrician. Many parents often find these habits come and go without any pattern and can resolve on their own without intervention. If intervention is needed, your pediatrician can direct you to the most beneficial treatment path.

Positive Habits to Encourage

While some habits may raise concern, parents can focus on fostering positive habits that support their child’s development and well-being. Some examples include:

  • Looking both ways before crossing the street
  • Putting on a seatbelt when getting in the car
  • Stopping at the sidewalk when playing outside to stay safe
  • Turning in homework folders upon entering the classroom
  • Saying thank you after receiving a gift
  • Greeting a parent after a separation

Encouraging positive habits can help children develop good routines and behaviors. Parents often find that positive habits are exhibited more frequently than negative ones, especially when they take the time to notice and praise their child’s good behaviors.

If you have concerns about negative habits they should be brought to the attention of your child’s physician.
