<p>If he is able to fit everything, a backpack seems to work really well when I have seen the swabs running up the stairs with their luggage. He may need a larger backpack than he has for school but it is hard to say. I don’t recall that we had to send sheets. I believe they were issued when he got there. Obviously things change over the years, but I would caution you not to send or take anything that is not on the list. I hope that helps 
Best of luck to your family.</p>
