Why is my toddler ... so aggressive or shy?

 by Vincent Iannelli, MD

These can be normal personality variations. Some children can be very active, aggressive and always need to be in control. If your child has this type of personality, and he is overly aggressive and even violent, then it is important to supervise him around other children and provide him with an outlet for his aggressive tendencies through physical activities. Treatment of this type of behavior problem consists of setting firm limits and giving lots of praise when he isn't being aggressive and over time he will learn to control his impulses and will be less aggressive.

Being shy can also be a normal personality variation. It is best to not push your child. Instead let him slowly adjust to new people and new situations. He will gradually become more secure and confident and become less shy if you let him move at his own pace.
