I have a 17 yo daughter. I foolishly gave in to giving her an iPhone when she was 13. My husband died 4 years ago. Because of a rebellious attitude of her older sister, I realized these iPhones were causing some troubles..disrespect, individualism, family division..so I took the phones away when she was 14 1/2 . She is now asking to have “her” phone back, she reasons, “for communication”. I don’t think it’s a good thing. Do you have any advice?
