My DD will be a day student come fall. However, she is away for the entire summer, and overseas, for the first time. One month is done, but another three weeks, two days, to go until she returns to the USA. We insisted on extensive contact the first two weeks, but, upon seeing that all was well, we eased up. A short (really short) text daily is what we are getting at this point. Have Skyped three times in five weeks. Basically, I agree with the “no news is good news” theory. It is clearly harder on the parents than the kids! Good luck.
