DEAR DOCTOR K: My middle-schooler spends a lot of time studying. But his grades have dropped, and I see him getting more and more frustrated. What could be going on, and what can I do?
DEAR READER: Many children have problems with schoolwork or homework at one time or another. These problems usually do not last long. But if your son is still getting poor grades (C or below) despite working hard, it could be a sign that your son has a learning disability or some other problem that needs help.
