A child who often hits, slaps, and bites other children or destroys toys is not going through a stage. He is behaving in an aggressive way that is upsetting to parents and other children. Aggressive behavior includes:

• Breaking things on purpose
• Pushing, kicking, biting, or hitting other children
• Name calling, swearing, or threatening playmates

The following suggestions may help you to help your child.

• Set firm limits. Make it clear to your child that being mean is not OK. Give clear messages such as “we don’t hit people.” Always supervise your child when he is playing with other children so that you can quickly step in if needed. Never allow aggressive behavior, even in play. Do not roughhouse with or spank an aggressive child. To do so will encourage aggressive behavior.
• Be a good role model. Always show self-control. You can’t teach your child self-control when he sees you lose your temper, threaten, or hit people. It helps if you do not use physical punishment, such as spanking. Spanking may be very confusing to an aggressive child if you have just told him not to hit people. Make sure that everyone who cares for your child agrees to use the same type of discipline.
• Teach healthy ways to express feelings. Every child is different, and what works for one child may not work for another. How your child expresses his feelings will also change as he grows older. Here are some ideas for other activities your child can do when he starts to get upset.
  • Pound play dough, run, play sports, do martial arts, or do some jumping jacks.
  • Talk about feelings.
  • Write, paint, or play music.
• Give consequences. Immediately remove your child from the situation when he starts to act aggressively. Use time out, usually 1 minute for each year of age. End the time out when he has calmed down and is quiet. Do not spank, hit, or verbally abuse your child. These kinds of punishment can teach your child to hit or verbally abuse others. Be consistent.
• Reward non-aggressive behaviors: Some children misbehave to get attention. You can help prevent this if you praise your child when he behaves well. Tell your child how proud you are. Also say something like, “You should be proud of yourself.”
• Keep your child away from violence. The less violence your child sees, the less likely he is to be aggressive with others. Keep your child away from people who act aggressively. Make sure there is no violence in the home and that your child is not a victim of abuse. Do not let your child watch violent TV shows or movies or play violent games. Check the age rating for any game that your child plays, including games that are played on friends devices.

If your child is aggressive for longer than a few weeks, or if you cannot cope with his behavior on your own, see your healthcare provider or a mental health professional. Get emergency care if your child has serious thoughts of suicide or self-harm, violence, or harming others.
