Biting as a Behavior Problem - Topic Overview

It is normal for infants and young children to occasionally bite. But sometimes biting points to a more serious behavioral problem related to hostility and aggression. A child should be evaluated by a doctor if biting:

  • Is frequent and continues despite caregiver efforts to control it.
  • Occurs after 3 years of age.
  • Occurs in a variety of settings.
  • Injures other people.
  • Occurs out of general anger and/or aggression rather than out of frustration or desire for an object.
  • Occurs with other aggressive behaviors, such as hurting animals.
