My son, 18, started university in September. I pop over to see him every 2 weeks with his little sister and we have lunch, go to the cinema, visit a museum, etc. We only stay for the afternoon. My husband thinks this is ridiculous. He says I should leave my son alone and that I am smothering him. Needless to say, he hasn't visited our son at all. I miss my son so much, but I don't think a few hours a fortnight is excessively clingy?
