Rebelmum "studies reckon that children who watch more tv do worse at school"
So where did you read this garbage and how exactly did the researchers quantify it? Did they have a control group and did both groups have exposure to exactly the same factors (social, emotional, familial, moral, intrinsic) that would enable a direct mapping of the results?
I grew up watching TV. Sometimes, my brothers would watch 3 hours a day!. Sometimes we would watch none!
Guess what?
We also played outside, we were members of our local library so we read a lot, we can all construct sentences using words with more than two syllables, we have independent thoughts and are able to construct as well as deliver analytical arguments and I have a PhD in Chemistry.
There is a big difference between plonking a child in front of a TV all day and ignoring it as oppose to engaging with a child through play, talk, reading and heaven forbid, watching an interesting programme (for the child) like Thomas the tank engine!
I'm just waiting for some fountain of wisdom to claim that children of the working classes suffer more than those with middle class parents because they watch more TV.
