I think expecting to be in contact with your children every day is way over the top and smacks of trying to keep them tied to your apron strings.
Both my children live 100 miles + from us.I speak to them most weeks and otherwise email if necessary or follow them on Facebook. They are now in their late 40s and do not want their parents constantly checking up on them.
As a child from an army family, we always lived miles from family and rarely had a phone. My parents kept in touch with their parents by monthly letters and when my sisters and I were at boarding school we got weekly letters.
When I grew up, was working and then married, I would ring home once a week.
After my mother died, I started ringing my father more frequently, but he firmly put a stop to that and we went back to the weekly pattern. He didn't want us constantly checking up on him.
