How long should a parent wait before freaking out and organizing a search party?

In response to one such question, Duke responded:

“Most parents find that communication with their children drops in frequency as time passes and the students become more familiar with and invested in their college experiences. This is a good sign. If there is a sudden increase in e-mail, text or phone call frequency, it may signal a problem but I always say, it is at this point that parents need to encourage kids to solve their own problems through use of campus resources. This can be hard for parents, but it’s important for the development of independence in the children.”

Lots of people chimed in with their own opinions, including this one: ”LEAVE THEM ALONE, PARENTS!”

When I suggested that students and parents come up with a basic plan of how often to chat, Duke added: A “good plan is to allow the students to call you when they wish. Of course, if you don't hear anything for a week or more, a gentle nudge can be helpful and reassuring.”

Another reader then made us all laugh with this comment: “I agree with Mr. Duke about a ‘gentle nudge’ if the student doesn’t call very often, but it depends on the student. One of mine needed a ‘gentle sledgehammer’ to get him to call more than once a month.”
