I don't think parents need to worry. Loving teachers is a normal psychological activity, which accords with psychological theory. This is a special reaction of age. To some extent, loving teachers may be beneficial to students' learning, because it can improve students' preference for related teachers' courses, so as to learn this course better. What parents need to do is to care more about their children and give them proper reminders and guidance. I don't think it is necessary to care too much about others.
