Do not call every day for the first week. No freshman college student wants Mommy and Daddy checking up on them daily. Phone bills can really add up. Be a shoulder to cry on. Sometimes college life can be stressful and frustrating, even for the most studious or sociable kids.
College is more than classes and homework.
Experience with extra-curricular activities is what will set students apart in the workplace. Encourage your child to be active in their field of study. Join clubs and honor societies. Enjoy your freedom. You will miss your child, as any parent would.
