In my experience, the main skill that college students need to develop is knowing when to ask for support. I have watched students let something get out of hand rather than ask for help, either because they do not know about the appropriate resources or because they do not want to appear inept. On the other hand, I have also seen students immediately reach out to have someone help them without ever trying to solve the problem first. While we do want students to develop their autonomy, we also want them to successfully function interdependently and rely on others for support.
If you notice your child struggling and it is not an emergency or health-related situation, rather than solve the problem yourself or calling the appropriate campus resources for him/her, I suggest that you ask questions that will help him/her get to a solution or that you name the campus resources available and suggest that he/she reach out to them. That way you are empowering them to own the situation, while also acting as a safety net.
