Dr. Greene’s Answer:
With kids who are disruptive, working on empathy can be very helpful–not telling her what to do, but helping her learn to identify what others are feeling (which can lead to changes in behavior).
It is also good to keep in mind–especially if it runs in the family–that if ADHD shows up at that age, the most common symptoms are the ones you have described. It may be worth an evaluation by her pediatrician.
