What is the best advice you received when sending your first to college?

@fauxmaven did your daughter go to a school close to you? The reason I ask is I’ve heard not to go on Parents weekend more than once, but my son is going to be across the country, so I wonder if it’s better to go sooner rather than later. His birthday is in early November and was planning to go then, especially since we aren’t necessarily having him come home for Thanksgiving.
