Joanna Fortune: My 11-year-old is constantly checking her new phone 

"While you can be clear that the same rules that apply to an 11-year-old are not the same for grown-ups, there are ones you can follow, such as the ‘one screen at a time’ rule and not having phones at mealtimes or in your bedroom."

My 11-year-old got a phone for Christmas. Already she’s spending hours messaging her friends and is constantly checking her phone. I took it off her last week for a day because I was concerned about her. She got distraught, saying I was cutting her off from her friends. What should I do?
