This is all new to me.

Next week at this time, I will have helped my 19-year-old son with moving into his room at university. It’s his first year so everything is all new. I'm over worrying myself sick, but I'm trying to be cool. I can't eat, my sleep is disturbed, and I already miss him even though he hasn't left yet. How often should I contact him? I'm not sure. I don’t want to look like I don’t give a damn in what he is doing! How often do you and your son or daughter communicate with you? What is acceptable amount during the initial weeks so that I don't push him away? After that, how many interactions or visits? Since he is in university, my son is more than 3.5 hours away but he has never spent more than a week apart. His course is 4 years and at the moment I feel like I won’t cope for this length of time.
