Dd is 13 (yr8). She spends all day in her bedroom on the phone to her friends. It's not like she's just talking but they kind of just get of with their day whilst on the phone. They have done homework together and revision and she's done quite a bit of art. However, unless you call her for food or some kind of pre-arranged activity she doesn't move from her desk. I would estimate that today she will have spent about 7 hours up there. I don't think that's healthy and have said once 8 30 comes she needs to put the phone away so she can have some away time from it. Obviously she thinks I am entirely unreasonable. Am I?
