Find out first what you are concerned about. Is it purely academic, course load, major selection? or is it social and emotional issues? such as depression, interaction with others? If you are concerned academic issues, do not be. Let your child face the problem, and find a balance.
If you are concerned about emotional and social issues, help your student identify potential contacts , listen to your student, listen to what he is saying and what he is not saying.

"Let your child handle problems on their own unless … Parents know their children better than anyone else and if they hear what I call ‘that voice’ from their children – the voice which is different from ordinary complaining, the voice that really means the child is in trouble, they should call the college. Don’t come running, just call the college. Good places to start would be the Office of the Dean of Students or the Dean of the College, perhaps the Resident Advisor of the child’s dormitory. No matter who is called, all the relevant people will be notified and help will be set into motion. College professionals are very experienced in dealing with these situations. You encourage your children and support them. Express confidence in their ability to deal with what’s going on and wait for them to work things out."
