Why does my son sleep till 5 pm when home? I am concerned he can't sleep in his dorm room should I ask counselor?

No counselor. I'd ask your son - he knows how he sleeps at school. Tell him you're concerned about how long he sleeps at home and you'de like to spend more quality time with him and shift into his habits at school - facebook, texting, etc. That interfere with appropriate sleep (8 hours per night is ideal).
